Product details

Description

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.

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 few external components. VDD ISRC ____________________________Features o High Accuracy (within ±0.1% of sensor’s repeatable errors) o Compensates Offset, Offset TC, FSO, FSO TC, Temperature/Pressure.
