VOUT+ (Pin 1) - This is the positive output of the amplifier. The output is taken as a differential signal from the amplifier.
VOUT- (Pin 2) - This is the negative output of the amplifier, providing the complementary part of the differential signal.
VCM (Pin 3) - The common-mode voltage input. This pin adjusts the common-mode level for the differential amplifier to function correctly with single-ended signals.
IN+ (Pin 4) - The non-inverting input of the amplifier. Signals applied here are amplified with positive gain.
IN- (Pin 5) - The inverting input of the amplifier. Signals applied here are amplified with negative gain.
GND (Pin 6) - Ground connection for the device. Ensures that all other voltages are referenced to the same level.
AVDD (Pin 7) - The positive voltage supply pin. It provides power to the analog circuitry of the device. This is typically between 3V and 5V.
DVDD (Pin 8) - The digital supply voltage pin. This supplies power to the internal digital logic circuits of the amplifier.
NC (Pins 9 and 10) - These pins are not connected to any internal circuitry. They can be left unconnected in a circuit.
VREF (Pin 11) - This pin provides a reference voltage that helps to set the common-mode voltage at the output of the amplifier.
SHDN (Pin 12) - This is the shutdown pin. If logic low, the device enters a low-power state, and if logic high, the amplifier operates normally.
OUT+ (Pin 13) - Positive output of the differential signal from the amplifier.
OUT- (Pin 14) - Negative output of the differential signal from the amplifier.
REF+ (Pin 15) - A positive reference voltage pin used for setting internal signal processing levels.
REF- (Pin 16) - A negative reference voltage pin used for setting internal signal processing levels.
