EB-TK2050-6 Class-T Digital Audio Amplifier Evaluation Board 6 Channel TK2050 Reference Board
Technical Information Revision 1.4 - February 2002
General Description
The EB-TK2050-6 (a six channel TK2050 Evaluation Board) is a 50 Watt per channel (continuous average, 0.1% THD+N) audio amplifier that utilizes three TK2050 Amplifier Chipsets. The TK2050 is a two channel, 50 Watt per channel audio amplifier IC that uses Tripath's proprietary Digital Power Processing technology. For additional information on the TK2050 Amplifier Chipset, please refer to the TK2050 Data Sheet.

Operating Instructions Power Supply Connection
This board requires a single power supply rail (and ground) to operate. The minimum working voltage on this rail is 7V, and the maximum is 36V. For maximum power operation, the power supply should have at least a 10 Amp rating. The TK2050 chipset also requires a 5 Volt supply for the power processor logic, but this 5V supply is generated on-board by the linear voltage regulator at U10. Note: this regulator is limited to 35V input. For operation of the EB-TK2050-6 at it's absolute maximum rating of 36V, the on-board 5V supply must be disabled (at J53) and the an external +5V supply (1A) must be used. Rail voltage is connected at J28 (+) and J30 (GND).
Input Connection
The audio inputs (J21, J22, J23, J24, J25, J26) use industry standard RCA Connectors. The Mute switch (SW1) should be enabled when inserting and removing RCA cables.
Output Connection
The outputs of the board are provided through connectors J1-J12. The output connectors are standard banana 0.188" receptacles. The 6 Channel EB-TK2050-6 outputs are in phase with each other. It should be noted that the TK2050 is an inverting amplifier.
Switches and Jumpers
Switch SW1 is a toggle switch that mutes all 6 channels. Jumper J36, J42, and J48 are labeled MUTE but are used only when SW1 is not loaded. Do not use these jumper positions, or damage to the board may occur Jumper J53 enables (on) and disables (off) the on-board 5V regulator.
Indicators
There are two LEDs that indicate power supply conditions. D1 indicates 5V condition and D2 indicates Vcc condition. A green light indicates operational voltage on each supply. If there is an undervoltage condition, the FAULT LEDs will glow red. Each channel pair has two LEDs that indicate the mute status and the temperature of the power die. The HMUTE LED is red when muted, and is unlit in normal operation. The TH_WAR LED is lit when its corresponding power die (mounted on the underside of the board) reaches a temperature of 130 degrees C. The TH_WAR LED is unlit in normal operation.

Usage Notes
We recommend bringing up the amplifier as follows: 1. Connect loads to the individual channels. Note that unloaded channels are allowed, as the Tripath application circuit is tolerant of very high impedances. Also note the polarity markings on the outputs.
2. Mute the amplifiers by sliding SW1 to the right (toward the outputs).
3. Connect the input sources to RCA connectors J21-J26. Note that channel pairs "cross over" to the corresponding outputs - that is, Input 1 is to the left of Input 2, but Output 1 is to the right of Output 2. This is noted on the board silkscreen. 4. If you are using an external 5V supply, connect it to J27 (+5) and J29 (GND), and remove J53. If you are using the on-board 5V supply, simply leave J53 in place. 5. Connect the main power supply to J28 (Vcc) and J30 (GND). 6. Bring up the power supply (supplies). If an external 5V supply is used, bring it up before the main supply. Both power supply indicator LEDs should be illuminated and green. If either of the supply LEDs are unlit or the FAULT LEDs are lit, recheck your supplies and connections. 7. Unmute the amplifiers by sliding SW1 to the left (toward the inputs). The HMUTE LEDs should turn off. 8. The amplifiers are now ready for use.

Heat Sink Considerations
The heatsinks supplied on the EB-TK2050-6 allow for operation of the individual amplifiers at roughly 15W continuous output per channel, assuming 25 degrees C ambient conditions and zero airflow. Once at a stable operating temperature, the amplifiers can be run at maximum output long enough for test purposes. This heatsink rating will thus permit the standard 1/3 power testing for amplifier certification. Note that the supplied heatsinks are not sufficient to drive the amplifiers at their full rated output on a continuous basis at 25 degrees C and with zero airflow. Appropriate heatsink size and configuration is implementation specific, taking into account anticipated power levels, ambient air temperatures, and free airflow velocities/volumes. Each amplifier pair is equipped with a thermal warning LED (denoted TH_WAR on the silkscreen) that will light when the power die temperature reaches 130 degrees C. When die temperature reaches 150 degrees C, the amplifier will shut down to prevent any damage to the die.

Performing Measurements on the EB-TK2050-6
The TK2050 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, can be 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 output filter has a very sharp roll-off just beyond the audio band or the bandwidth of the measurement instrument is low-pass filtered, some of the inaudible noise components introduced by the TK2050 switching pattern will degrade the measurement. One feature of the TK2050 is that it does not require large multi-pole filters to achieve excellent performance in listening tests, which are often 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-TK2050-6 Evaluation Board has a simple two-pole output filter with excellent performance in listening tests. See Tripath Application Note 4 for more information on bench testing.
