MAX1458 Description
The MAX1458 highly integrated analog-sensor signal processor is optimized for piezoresistive sensor calibration and pensation without any external ponents. It includes a programmable current source for sensor excitation, a 3-bit programmable-gain amplifier (PGA), a 128-bit internal EEPROM, and four 12-bit DACs. Achieving a total error factor within 1% of the sensor’s repeatability errors, the MAX1458 pensates...
MAX1458 Key Features
- Pretest: Data acquisition of sensor performance under the control of a host test puter
- Calibration and pensation: putation and storage (in an internal EEPROM) of calibration and pensation coefficients puted
- Final test operation: Verification of transducer calibration and pensation without removal from the pretest socket. Alth
- Dice are tested at TA = +25°C, DC parameters only
