Overview
Description
The ZSC31010 is a CMOS integrated circuit, which enables easy and precise calibration of resistive bridge sensors via EEPROM. When mated to a resistive bridge sensor, it will digitally calibrate offset and gain with the option to calibrate offset and gain coefficients and linearity over temperature. A second-order compensation can be enabled for temperature coefficients of gain or offset or bridge linearity. ZSC31010 communicates via IDT's ZACwire™ serial interface to the host computer and is easily mass calibrated in a Windows™ environment. Once calibrated, the output SIG™ pin can provide selectable 0 to 1 V absolute analog output; rail-to-rail ratiometric analog output; or digital serial output of bridge data with optional temperature data.
Features
- Digital compensation of sensor offset, sensitivity, temperature drift and non-linearity
- Accommodates differential sensor signal spans from 3 mV/V to 105 mV/V
- ZACwire™ one-wire interface (OWI)
- Internal temperature compensation and detection via bandgap PTAT (proportional to absolute temperature)
- Optional sequential output of both temperature and bridge readings on ZACwire™ digital output
- Output options: ratiometric analog voltage, absolute analog voltage, digital one-wire-interface
- Supply voltage 2.7V to 5.5 V, with external JFET 5.5V to 30 V
- Current consumption, depending on adjusted sample rate, 0.25 mA to 1 mA
- Wide operational range -50°C to +150°C
- Fast response time 1 ms
- High voltage protection up to 30V with external JFET
- Buffered and chopper-stabilized output DAC

ZSC31015 4-20mA Output Example
Hello there, I plan to use the ZSC31015 IC in my electronic design. While doing this work, I found a very nice document that was published. I am sharing the link of the document with you: www.renesas.com/.../zsc31010-zsc31015-application-note-analog-4-20ma-current-loop ...

Although VDD does not change, the output of the ZSC31015 integrated circuit slowly drifts upwards. What could be the reason for this upward drift?
Hello,Hello,We have produced a pressure transmitter with a 4-20ma output using the ZSC31015 series Resistive Sensor Signal Conditioner. We used the ZSC31010 / ZSC31015 Application Note - Analog 4-to-20mA Current Loop Output Applications document during production. However, after calibrating, the pressure slowly drifts upwards after initially ...

A brief introduction and overview of IDT's (acquire by Renesas) sensor signal conditioner evaluation kits. Evaluation kits generally consist of three parts: a communication interface board, a device board, and a sensor simulator board - all connected together. A sophisticated software GUI accompanies the kit, enabling an engineer to learn how to use the part rapidly, do quick prototyping, and practice calibrations.
