ZSSC3018
Versatile, High Resolution 18-Bit
Sensor Signal Conditioner
ZSSC3018
Datasheet
Brief Description
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 high-
speed control, safety, and real-time sensing applications with the
highest requirements for energy efficiency.
Features
Flexible, programmable analog front-end design; up to 18-bit
analog-to-digital converter (ADC)
Fully programmable gain amplifier with gain range from 6.6 to
216 (linear)
Internal auto-compensated temperature sensor
Digital compensation of individual sensor offset; 1st and 2nd
order digital compensation of sensor gain as well as of 1st
and 2nd order temperature gain and offset drift
Programmable interrupt operation
High-speed sensing: e.g., 16-bit conditioned sensor signal
measurement rate >500s-1
Typical sensor system can achieve an accuracy of better than
±0.10% FSO* @ -40 to 125°C
Benefits
Integrated 26-bit calibration math DSP
Fully corrected signal at digital output
Layout customized for die-die bonding with sensor for high-
density chip-on-board assembly
One-pass calibration minimizes calibration costs
No external trimming, filter, or buffering components required
Highly integrated CMOS design
Integrated reprogrammable non-volatile memory
Excellent for low-voltage and low-power battery applications
Optimized for operation in calibrated resistive sensor
(e.g., pressure) or calibrated absolute voltage sensor
(e.g., thermopile) modules
