ZSSC3230AI3R ES

Overview

The ZSSC3230AI3R ES is a capacitive sensor signal conditioner integrated circuit manufactured by Renesas Electronics. It operates within a supply voltage range of 1.68 V to 3.6 V and draws a typical operating current of 750 uA. The device supports an I2C interface for digital output communication. It functions as a single-channel signal conditioner designed for capacitive sensing applications. The component is housed in a PQFN-24 package with dimensions of 4x4 mm, suitable for surface mount installation. It features an internal reference type and accepts both analog and digital input signals.

Feature Summary

• Capacitive sensor signal conditioning for single-channel applications
• I2C digital interface for system communication
• Internal reference configuration for simplified design

Applications

• Capacitive touch sensing interfaces
• Proximity detection systems
• Level sensing applications

Procurement Notes

Verify the exact suffix designation when sourcing, as the 'ES' variant may indicate engineering sample or specific revision status distinct from standard production parts. Confirm RoHS compliance details through official documentation prior to integration. Check lifecycle status carefully, as this specific part number may be marked obsolete or have limited availability compared to newer revisions in the ZSSC3230 series. Ensure compatibility with existing PCB footprints and firmware requirements before procurement.

Selection Notes

Select this component for designs requiring a dedicated capacitive signal conditioner with I2C connectivity. Consider the 1.68 V to 3.6 V operating range for low-power embedded systems. Evaluate the PQFN-24 package size against board space constraints. Verify that the single-channel architecture meets the specific sensing requirements of the target application without needing additional multiplexing.

Part Context

This part belongs to the ZSSC3230 series of sensor signal conditioners from Renesas Electronics. The series is designed to bridge capacitive sensors with digital processing units. The AI3R ES designation typically denotes a specific tape and reel packaging configuration and potentially an engineering sample or early revision status within the broader product family.
