ZSSC3240CC5B

Overview

The ZSSC3240CC5B is a sensor signal conditioner IC designed for resistive bridge sensors. It features a programmable measurement sequencer that multiplexes between bridge, temperature, and diagnostic measurements. The device provides offset compensation and amplification with a gain factor of up to 540V/V to optimize the ADC input range. It digitizes signals up to 24-bit resolution and uses an internal DSP for linearization and temperature compensation. Output options include digital interfaces, analog voltage (up to 16-bit), or industrial current loops.

Feature Summary

• Integrates a programmable measurement sequencer for multiplexing sensor inputs
• Provides high-gain amplification and 24-bit digitization for precision conditioning
• Includes internal DSP for post-processing, linearization, and temperature compensation

Applications

• Pressure sensor platforms utilizing resistive bridge elements
