Texas Instruments  PGA400QRHHTEP

The PGA400-EP is an interface device for piezoresistive, strain gauge and capacitive sense elements. The device incorporates the analog front end that directly connects to the sense element and has voltage regulators and oscillator. The device also includes sigma-delta analog-to-digital converter, 8051 WARP core microprocessor and OTP memory. Sensor compensation algorithms can be implemented in software. The PGA400-EP also includes 2 DAC outputs.
