JHM1101 Sensor IC Automotive Sensor Signal Conditioning IC MSOP-10

JHM1101 is a highly stable and reliable signal conditioning integrated circuit designed for differential resistive bridge sensor signals. Measured and correct bridge values are provided at SO pin, which can be configured as an analog voltage output or as a single-wire digital output.

JHM1101 also features a 12-bit DAC, which conveniently outputs analog signals that are linear proportional to the differential input of the sensor. With an external JFET to form a regulated circuit, the JHM1101 can operate directly with supply voltage up to 30V, making it convenient to meet the needs of many automotive, industrial and other applications.
