MAX1457 Datasheet (Maxim) - 0.1%-Accurate Signal Conditioner for Piezoresistive Sensor Compensation

MAX1457, 0.1%-Accurate Signal Conditioner for Piezoresistive Sensor Compensation

The MAX1457 is a highly integrated analog-sensor signal processor optimized for piezoresistive sensor calibration and compensation.

It includes a programmable current source for sensor excitation, a 3-bit programmable-gain amplifier (PGA), a 12-bit ADC, five 16-bit DACs, and an uncommitted op amp.

MAX1457 Features

* of the MAX1457 facilitate manufacturing and calibration of multiple sensor modules, thus lowering manufacturing cost. Although optimized for use with piezoresistive sensors, the MAX1457 may also be used with other resistive sensor types (i.e., accelerometers and strain gauges) with the addition of a
