PGA400-Q1 Datasheet (Texas Instruments) - Pressure-Sensor Signal Conditioner

PGA400-Q1, Pressure-Sensor Signal Conditioner

The PGA400-Q1 is an interface device for piezoresistive, strain gauge, and capacitive-sense elements.

The device incorporates the analog front end (AFE) that directly connects to the sense element and has voltage regulators and an oscillator.

The device also includes a sigma-delta analog-to-digital
