PGA308 - Auto-Zero Sensor Amplifier

Description

The PGA308 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, a digital One-Wire, UART-compatible interface.
