Brief 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

Sensor connection and common mode check (sensor aging

detection)

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.

AEC-Q100 qualification (temperature grade 0)

Physical Characteristics
