ZSSC3018 Versatile, High Resolution 18-Bit Sensor Signal Conditioner Datasheet

2020-05-13
The ZSSC3018 is a sensor signal conditioner (SSC) integrated

circuit for high-accuracy amplification and analog-to-digital

conversion of differential or pseudo-differential input signals.

Designed for high-resolution sensor module applications, the

ZSSC3018 can perform offset, span, and 1st and 2nd order

temperature compensation of the measured signal. Developed for

correction of resistive bridge or absolute voltage sensors, it can

also provide a corrected temperature output measured with an

internal sensor.

The measured and corrected sensor values are provided at the

digital output pins, which can be configured as I2C (≤ 3.4MHz) or

SPI (≤ 10MHz). Digital compensation of signal offset, sensitivity,

temperature, and non-linearity is accomplished via a 26-bit

internal digital signal processor (DSP) running a correction

algorithm. Calibration coefficients are stored on-chip in a highly

reliable, non-volatile, multiple-time programmable (MTP) memory.

Programming the ZSSC3018 is simple via the serial interface. The

interface is used for the PC-controlled calibration procedure,

which programs the set of calibration coefficients in memory. The

ZSSC3018 provides accelerated signal processing, increased

resolution, and improved noise immunity in order to support highspeed control, safety, and real-time sensing applications with the

highest requirements for energy efficiency.
