35, Low-Voltage, SPST/SPDT Analog Switches in UCSP Package
General Description
The MAX4696/MAX4697/MAX4698 low on-resistance (RON), low-voltage analog switches operate from a single +2.0V to +5.5V supply. The MAX4696/MAX4697 are single-pole/single-throw (SPST) analog switches, and the MAX4698 is a single-pole/double-throw (SPDT) analog switch. The MAX4696 is a normally open (NO) switch, and the MAX4697 is a normally closed (NC) switch. When powered from a 2.7V supply, these devices feature 35 (max) RON, with 2 (max) RON matching and 13 (max) flatness. The MAX4696/MAX4697/MAX4698 offer fast switching speeds (tON = 80ns max, tOFF = 25ns max). The MAX4698 offers a break-before-make function. The digital logic inputs are 1.8V logic compatible from a +2.7V to +3.3V supply and are TTL/CMOS compatible from a +4.5V to +5.5V supply. The MAX4696/MAX4697/ MAX4698 are packaged in the chip-scale package (UCSPTM), significantly reducing the required PC board area. The device occupies only a 1.50mm 1.02mm area. The 3 2 array of solder bumps are spaced with a 0.5mm bump pitch. o 6-Bump, 0.5mm Pitch, UCSP o RON 35 max (+3V Supply) 20 max (+5V Supply) o 2 max RON Match Between Channels o 13 max RON Flatness Over Signal Range o Low Leakage Currents Over Temperature 1nA (max) at TA = +25C o Fast Switching: tON = 80ns, tOFF = 25ns o Guaranteed Break-Before-Make (MAX4698) o +2.0V to +5.5V Single-Supply Operation o Rail-to-Rail(R) Signal Handling o Low Crosstalk: -75dB (100kHz) o High Off-Isolation: -75dB (100kHz) o 1.8V CMOS Logic Compatible o -3dB Bandwidth: >200MHz

Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in this data sheet. Note 3: Guaranteed by design. Note 4: RON = RON(MAX) - RON(MIN), between switches. Note 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal ranges. Note 6: Off-Isolation = 20log10 (VCOM / VNO), VCOM = output, VNO = input to off switch. Note 7: Between switches. Note 8: UCSP parts are 100% tested at +25C only, and guaranteed by correlation at the full-rated temperature.

Applications Information
Logic Inputs
Where the MAX4696/MAX4697/MAX4698 have a +3.3V supply, IN may be driven low to GND and driven high to 5.5V. Driving IN rail-to-rail minimizes power consumption. Logic inputs accept up to +5.5V regardless of supply voltage.
Power-Supply Sequencing and Overvoltage Protection
CAUTION: Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to devices. Proper power-supply sequencing is recommended for all CMOS devices. Always apply V+ before applying analog signals, especially if the analog signal is not current limited. If this sequencing is not possible, and if the analog inputs are not current limited to <20mA, add a small-signal diode (D1) as shown in Figure 6. Adding a protection diode reduces the analog range to a diode drop (about 0.7V) below V+ (for D1). RON increases slightly at low supply voltages. Maximum supply volt-
Analog Signal Levels
Analog signals that range over the entire supply voltage (GND to V+) are passed with very little change in R ON (see Typical Operating Characteristics). The switches are bidirectional, so the NO, NC, and COM terminals are both inputs or outputs.

age (V+) must not exceed +6V. Protection diode D1 also protects against some overvoltage situations. No damage will result on the circuit in Figure 6 if the supply voltage is below the absolute maximum rating and if a fault voltage up to the absolute maximum rating is applied to an analog signal terminal.
