ZSSC3027AC7B

Overview

The ZSSC3027AC7B is a sensor signal conditioner integrated circuit manufactured by Renesas Electronics Corporation. It belongs to the ZSSC3027 family and is designed for high-accuracy amplification, digitization, and sensor-specific correction of sensor signals. The device features a flexible, programmable analog front-end with a scalable charge-balancing two-segment analog-to-digital converter capable of up to 16-bit resolution. It includes a fully programmable gain amplifier accepting sensors from 14 to 72 linear factor. The IC provides digital compensation for individual sensor offset, gain, and temperature drift via an internal digital signal processor. Calibration coefficients are stored in non-volatile memory, and the digital output supports I2C or SPI interfaces.
