Datasheet

Description

Features

The ZSSC3230 is a CMOS integrated circuit for accurate capaci-

tance-to-digital conversion and sensor-specific correction of

capacitive sensor signals. Digital compensation of sensor offset,

sensitivity, and temperature drift is accomplished via an internal

digital signal processor running a correction algorithm with

calibration coefficients stored in a nonvolatile, multiple-time

programmable (NVM) memory. Programming the ZSSC3230 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 ZSSC3230 is configurable

for capacitive sensors with capacitances up to 30pF and will

provide an output resolution that is scalable up to 18-bit. It is

compatible with single-ended capacitive sensors. Measured and

corrected sensor values can be output as I2C (≤ 3.4MHz).

Low current consumption: 1.3µA at 1 sample per second

Maximum target input capacitance: 30pF

Programmable capacitance span and offset

High sampling rate with 2ms at 14-bit resolution

ADC resolution: Adjustable in speed and resolution, 18-bit

maximum

Internal auto-compensated temperature sensor; not stress

sensitive

Programmable measurement sequence, single-shot and

automatic cycling of measurements with end-of-sequence

interrupt output

Oversampling modes using internal averaging

Interrupt features

The ZSSC3230 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.
