ZSSC3218 High-End 18-Bit Sensor Signal Conditioner
integrated circuit for high-accuracy amplification and
analog-to-digital conversion of a differential or
pseudo-differential input signal. Designed for highresolution sensor module applications, the
ZSSC3218 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 I2
C™* (≤ 3.4MHz) or SPI (≤ 20MHz).
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 ZSSC3218 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 ZSSC3218
provides accelerated signal processing, increased
resolution, and improved noise immunity in order to
support high-speed control, safety, and real-time
sensing applications with the highest requirements
for energy efficiency.
