HJ14520A/B/C is a silicon piezoresistive sensor conditioning circuit integrated using thick film technology, mainly consisting of the MAX1452 analog sensor signal processing circuit, a linear voltage regulator, two temperature compensation feedback resistors (RISRC and RSTC) of 75kΩ, series resistors at the power supply and output (which effectively protect the power supply and output from electrostatic discharge and short-term voltage surges) and reverse polarity protection, among others, further optimizing usage and increasing integration. It can withstand extreme environmental stress and harsh electromagnetic environments.
Product features include:
Suitable for various silicon piezoresistive sensors from 1mV/V to 40mV/V
Supports voltage/current excitation sensors
Equipped with amplification, calibration, temperature compensation functions, and can be digitally programmed
Analog channels and digital channels are completely separated
Low power consumption
Table-based temperature correction
Zero and full-scale calibration with up to 16-bit resolution
Reverse connection protection
Anti-static/surge protection
