POWER SUPPLIES
Three external power supplies are required to operate the EB-TK2150: VPP (referenced to PGND), VNN (referenced to PGND) and V5 (referenced to AGND). The V5 ground (AGND) must be kept separate from the VPP and VNN ground (PGND). PGND and AGND are joined at a common point on the EB-TK2150 with a ferrite bead (L1). There are two versions of the EB-TK2150. The "-1" or "LV" (low voltage) version operates from +/-29V to +/-45V, with +/-40V being the nominal supply voltage. The "-2" or "HV" (high voltage) version operates from +/- 39V to +/-60V with +/-54V being the nominal supply voltage. Operation outside these set minimum and maximum supply voltages will cause the TC2001 to shut off the output stages of the amplifiers. The removal of the under-voltage or over-voltage condition returns the TK2150 to normal operation. Please see the Over- and Under- Voltage Protection section of the TK2150 Data Sheet for a more detailed discussion of the rail supply range. The V5 supply voltage is 5V and should be well regulated. Please see the TK2150 Data Sheet for minimum and maximum values. The VPP and VNN power supply connection is made with a standard .156" Molex header (J5). The V5 connection is made with a standard .100" Molex header (J1). Please refer to the Board Connection Diagram for the header locations on the EB-TK2150 and the attached Bill-Of-Materials for the header part numbers. The TP2150 has an internal hysteretic buck converter, which, in conjunction with a few components supply the VN10 voltage required by the TP2150 MOSFET Driver. These external components include a PChannel FET, 100uF inductor, ultra-fast recovery rectifier diode, and a few passive resistors and capacitors. The diode may be replaced with a Shottky diode rated at least 200mA, 50nS and appropriately voltage rated.

Technical Information
OUTPUT
The output connections for each channel of the EB-TK2150 are made with standard .156" Molex headers (J101, J201). The output of the TK2150 is single-ended; therefore each output has a signal output and a ground output. Please refer to the Board Connection Diagram for the header locations and speaker connection polarity on the EB-TK2150.
BRIDGED OUTPUT
The EB-TK2150 can be run into bridged six or eight ohm loads. To operate in bridged mode, input equal magnitude but out of phase signals to IN1 and IN2. The output will then be derived from the "+" outputs located at J101 and J201. It should be noted that operating in bridged mode can theoretically increase the available output power by four times. But this extra output power also results in increased power dissipation for the output fets. If continuous output tests are required, additional heat-sinking may be required. Alternatively, the supply voltage of amplifier can be reduced to a level that produces 2.5-3 times the single ended power. A safe maximum operating supply voltage for the -1 board (with 6 ohm bridged load) would be +/-36V and for the -2 board (with 6 ohm bridged load) would be +/-50V. The TK2150 can be used for 4 ohm bridged operation (or below), but in most cases this will require using a lower supply voltage, due to increased power dissipation. For the FQP19N10 fets used on the -1 board, +/-28V is a safe voltage for operation assuming 4 ohm bridged load. For the FQP2572 fets used on the -2 board, +/40V is a safe voltage level for 4 ohm bridged load. These recommended supply voltages are below the levels of the "stock" -1 and -2 boards. To operate at these voltage levels the over/under voltage and feedback resistors will need to be changed. Please refer to the TK2150 data sheet for additional information on selection of external components or contact Tripath directly.
INPUT
The input connection for each channel of the EB-TK2150 is made using a dual RCA connector (female). The dual RCA connector is labeled AUDIO INPUT (J2). The red RCA is the input to CH1 and the white RCA is the input to CH2. These inputs share a common ground referenced to AGND. Please refer to the Board Connection Diagram for the connector locations on the EB-TK2150.
JUMPER SETTINGS
There is a 2-pin header for the MUTE (J4) control of the TK2150. With the jumper in place the part is unmuted. When the jumper is removed the mute pin is pulled high (5V) and the amplifier is muted. Please refer to the Board Connection Diagram for the connector locations on the EB-TK2150. To minimize turn on/off pops, place the amplifier in mute while bringing up/turning off the power supplies. INDICATOR LED'S The EB-TK2150 has a red LED (D1) labeled HMUTE. The HMUTE LED will glow red and both outputs are muted when a fault occurs or the MUTE jumper is removed. The most likely causes for a fault are overcurrent, over-voltage or under-voltage. Please refer to the TK2150 Data Sheet for a complete description of HMUTE. Please refer to the Board Connection Diagram for the LED location on the EB-TK2150.
OUTPUT OFFSET NULL
There are two potentiometers, R104 (Channel 1) and R204 (Channel 2) that are used to manually trim the output offsets to 0Vdc. Please refer to the Board Connection Diagram for the potentiometer locations on the EB-TK2150. The evaluation board is shipped with any offsets nulled within +/-10mV.

GAIN SETTING
The gain of the EB-TK2150-1 is set to 13.3V/V. The gain of the EB-TK2150-2 is set to 19.95V/V. The gain of the TK2150 is the product of the TC2001 (control stage) gain and the TP2150 (power stage) gain. The control stage gain is set to .664V/V. The TP2150 (power stage) gain is determined from the maximum allowable feedback level for the modulator. Once the designer chooses the maximum supply voltages the feedback level can be optimized and the power stage gain is set. From this point any minor gain adjustments can be made at the control stage. Before changing the gain of the EB-TK2150, please refer to the Amplifier Gain section of the EB-TK2150 Data Sheet.

PERFORMING MEASUREMENTS ON THE EB-TK2150
The TK2150 operates by generating a high frequency switching signal based on the audio input. This signal is sent through a low-pass filter that recovers an amplified version of the audio input. The frequency of the switching pattern is spread spectrum in nature and typically varies between 100kHz and 1MHz, which is well above the 20Hz - 20kHz audio band. The pattern itself does not alter or distort the audio input signal, but it does introduce some inaudible components. The measurements of certain performance parameters, particularly noise related specifications such as THD+N, are significantly affected by the design of the low-pass filter used on the output as well as the bandwidth setting of the measurement instrument used. Unless the filter has a very sharp roll-off just beyond the audio band or the bandwidth of the measurement instrument is limited, some of the inaudible noise components introduced by the TK2150 amplifier switching pattern will degrade the measurement by including out of band (audio) energy. One feature of the TK2150 is that it does not require large multi-pole filters to achieve excellent performance in listening tests, usually a more critical factor than performance measurements. Though using a multi-pole filter may remove high-frequency noise and improve THD+N type measurements (when

they are made with wide-bandwidth measuring equipment), these same filters degrade frequency response. The EB-TK2150 has a simple two-pole output filter with excellent performance in listening tests. (See Application Note 4 for additional information on bench testing)
