3 Description
The PGA400-Q1 device 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
converter (ADC), 8051 WARP core microprocessor,
and OTP memory. Sensor compensation algorithms
can be implemented in software. The PGA400-Q1
device also includes two digital-to-analog converter
(DAC) outputs.
