ZSSC3027AC1B

Overview

The ZSSC3027AC1B is a sensor signal conditioner integrated circuit designed for high-accuracy amplification and analog-to-digital conversion of differential input signals. It features a flexible, programmable analog front-end with a scalable, charge-balancing two-segment analog-to-digital converter capable of 16-bit resolution. The device includes a fully programmable gain amplifier accepting sensors from 14 to 72 linear factor. Internal auto-compensated temperature sensing and digital compensation for offset, gain, and temperature drift are provided. Calibration coefficients are stored in non-volatile memory, and the digital output supports I2C or SPI interfaces.
