0.1%-Accurate Signal Conditioner
for Piezoresistive Sensor Compensation

Note 1: Circuit of Figure 5 with current source turned off. This value is adjustable through a bias resistor and represents the IC cur-
rent consumption. This excludes the 93C66 EEPROM average current, which is approximately 13A at a refresh rate of 3Hz
(fCLK = 100kHz).
Note 2: Temperature errors for the entire range are compensated together with the sensor errors.
Note 3: The sensor and the MAX1457 must always be at the same temperature during calibration and use.
Note 4: This is the maximum allowable sensor offset at minimum gain (54V/V).
Note 5: This is the sensor’s sensitivity normalized to its drive voltage, assuming a desired full-span output of 4V and a bridge volt-
age of 2.5V. Lower sensitivities can be accommodated by using the auxiliary op amp. Higher sensitivities can be accommo-
dated by operating at lower bridge voltages.
