JHM110X is a high cost performance differential signal sensor conditioning IC chip, which integrated the 14-bit ADC and 12-bit DAC internally. The gain and input offset of the ADC are both configurable to be set for nearly all resistance bridge sensors. It could correct the offset of zero-point, sensitivity and temperature, and also the nonlinearity over temperature or resistance bridge of the sensor signal by the DSP.
The output pin SO provides selectable 0~1V analog voltage, rail-to-rail radiometric analog output, or digital data with optional temperature data or PWM signal.
Working temperature is from -40~+150°C with high reliability for the automotive sensors, and also other sensors which need the high-level stability.
Easy to use and the calibration could be completed by only two data collections. We provide the auto-calibration system to the customer so as to be more efficient.
Millions of JHM1101/1102 chips have been installed in the customers’ products and we’ve got rich experience about the applications of the JHM110X resistance bridge sensor signal conditioning integrated circuit chips.
