Magnetic Sensor Signal Conditioning Chip/Programmable Instrumentation Amplifier

The NSA5312 is a user programmable instrumentation amplifier. It is mainly used to provide voltage type drive signal for Wheatstone bridge sensors (such as TMR sensors),and amplify, calibrate and compensate the output signal to ensure that the sensor can get high linear output accuracy in a wide temperature range.

Product Features

•  Provide 2.5V / 4.096V voltage excitation

•  Provide 0.9456~1843x programmable gain setting

•  Provide 14-bit sensor sensitivity and offset calibration

•  Provide sensor temperature calibration based on lookup table

•  Programmable output signal bandwidth, with maximum signal bandwidth is about 600kHz

•  Fast response time <1us

•  Proportional output and fixed output are available. The output reference voltage is available in 0.5V/1.65V/2.5V.

•  Provide user programmable interface OWI, and support customer module level post-calibration

Application

•  Current sensor module

•  Pressure sensor module

•  Industrial transmitter
