General Description

The PGA309 is a programmable analog signal conditioner designed for bridge sensors.

The analog signal path amplifies the sensor signal and provides digital calibration for zero, span, zero drift, span drift, and sensor linearization errors with applied stress (pressure, strain, etc.).

The calibration is done via a One-Wire digital serial interface or through a Two-Wire industry-standard connection.
