Description

Features

ZSC31050 is a CMOS integrated circuit for highly accurate amp-

lification and sensor-specific correction of bridge sensor and

temperature sensor signals. The device provides digital com-

pensation of sensor offset, sensitivity, temperature drift, and non-

linearity via a 16-bit RISC microcontroller running a polynomial

correction algorithm.

Digital compensation of sensor offset, sensitivity, temperature

drift, and nonlinearity

Accommodates nearly all resistive bridge sensor types (signal

spans from 1mV/V up to 275mV/V)

Digital one-pass calibration: quick and precise

Selectable compensation temperature source: bridge,

thermistor, or internal or external diode

The ZSC31050 accommodates virtually any bridge sensor type

(e.g., piezo-resistive, ceramic thick-film, or steel membrane based).

In addition, it can interface to a separate temperature sensor. The

bi-directional digital interfaces (I²C, SPI, and ZACwire™) can be

used for a simple PC-controlled one-pass calibration procedure to

program a set of calibration coefficients into an on-chip EEPROM.

A specific sensor and a ZSC31050 can be mated digitally: fast,

precise, and without the cost overhead associated with trimming by

external devices or laser. The ZACwire™ interface enables an end-

of-line calibration of the sensor module.

Output options: voltage (0 to 5V), current (4 to 20mA), PWM,

I²C, SPI, ZACwire™ (one-wire interface), alarm

Adjustable output resolution (up to 15 bits) versus sampling

rate (up to 3.9kHz)

Current consumption: 2.5mA (typical)

Selectable bridge excitation: ratiometric voltage, constant

voltage, or constant current

Input channel for separate temperature sensor

Typical applications for the ZSC31050 include industrial, medical,

and consumer products. It is specifically engineered for most

resistive bridge sensors; e.g., sensors for measuring pressure,

force, torque, acceleration, angle, position, and revolution.

Sensor connection and common mode check (sensor aging

detection)

AEC-Q100 qualification (temperature grade 0)
