HJ417 is a proportional voltage transmission integrated circuit used for processing bridge signals. Its main feature is that the output signal can automatically track changes in power supply voltage proportionally, which is very necessary for control systems that share a common power supply. The device includes a high-precision instrumentation amplifier for processing differential input signals, a proportional output current source for exciting sensors, and an output stage with protection functions. The circuit gain, offset voltage, and output voltage range (maximum 0.2~4.8V) can be adjusted using external resistors. This circuit is ideal for processing differential output signals from silicon pressure sensors or magnetoresistive bridges and is also suitable for resistive temperature sensors. It can be widely used in automation control, industrial automation instruments, as well as front-end instrumentation amplification and transmission circuits for microcontrollers or A/D converter circuits.
Product features include:
Output signal voltage varies proportionally with power supply voltage;
Single power supply operation +5V±5%;
Low offset voltage and low offset voltage temperature drift coefficient;
Coefficient and offset voltage are adjustable;
Open collector output drives IOUT=10 mA;
Low noise;
Especially suitable for silicon pressure sensors and magnetoresistive bridge sensors.
