ZSC31050FAG1-T

Overview

The ZSC31050FAG1-T is an advanced differential sensor signal conditioner manufactured by Renesas Electronics. It accommodates nearly all bridge sensors via a programmable gain amplifier and ADC, handling signals from 1mV/V to 275mV/V. The device provides digital compensation for offset, sensitivity, temperature drift, and non-linearity using an internal microcontroller. It supports multiple output options including voltage (0V to 5V), current (4mA to 20mA), PWM, I2C, SPI, and ZACwire. Supply voltage ranges from 2.7V to 5.5V, with operation temperatures up to +150°C in an SSOP-16 package.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for moisture sensitivity level requirements during storage and handling. Ensure the specific suffix matches design specifications as variations may exist within the product family.

Selection Notes

Select this model when high-temperature operation up to 150°C is required alongside standard supply voltages. Consider the availability of multiple interface protocols if system integration demands flexibility between analog and digital outputs. Verify that the SSOP-16 package fits the PCB layout constraints.

Part Context

This component belongs to the ZSC31050 series of sensor signal conditioners designed for bridge sensor applications. It serves as a specialized interface IC within Renesas' portfolio, focusing on accurate signal processing for piezoresistive and steel-membrane-based sensors in demanding environments.

Replacement Considerations

The ZSC31050DAG1-T is a related variant within the same series but typically supports lower maximum operating temperatures. Verify thermal requirements and interface compatibility before substitution.
