ZSC31050FIG1-R

Overview

The ZSC31050FIG1-R is an advanced differential sensor signal conditioner manufactured by Renesas Electronics. It accommodates bridge sensors with signals from 1mV/V to 275mV/V and supports supply voltages between 2.7V and 5.5V. The device features digital compensation for offset, sensitivity, temperature drift, and non-linearity via a 16-bit RISC microcontroller. It offers multiple output options including voltage (0V to 5V), current (4mA to 20mA), PWM, I2C, SPI, and ZACwire. The component operates within a temperature range of -40°C to +125°C and is housed in an SSOP-16 package.

Procurement Notes

Verify the specific suffix FIG1-R against official Renesas documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with system requirements for I2C, SPI, or ZACwire interfaces. Confirm that the SSOP-16 form factor fits the target PCB layout. Check for any obsolescence notices or lifecycle status changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when precise digital calibration of resistive bridge sensors is required without external complex circuitry. It is suitable for applications needing flexible output formats such as 4-20mA or PWM alongside digital communication. Consider the operating temperature range and supply voltage limits to ensure they match the environmental conditions. Evaluate the need for specific diagnostic features if safety-critical performance is mandated.
