PGA308 Single-Supply Auto-Zero Sensor Amplifier
Texas Instruments PGA308 Single-Supply Auto-Zero Sensor Amplifier is a programmable analog sensor signal conditioner. The analog signal path amplifies the sensor signal and provides digital calibration for offset and gain. Calibration is done via the 1W pin. This is a digital One-Wire, UART-compatible interface. For three-terminal sensor modules, 1W may be connected to VOUT; then the assembly can be programmed through the VOUT pin. Gain and offset calibration parameters are stored on-board in seven banks of one-time programmable (OTP) memory. The power-on reset (POR) OTP bank may be programmed a total of four times.
