ADG2128YCPZ-REEL7

Overview

The ADG2128YCPZ-REEL7 is an I²C-compatible CMOS analog crosspoint switch array featuring a configuration of eight columns by twelve rows, providing 96 independent bidirectional signal channels. It operates with dual ±5 V or single +12 V supplies and supports standard, fast, and high-speed (3.4 MHz) I²C interfaces. The device includes double-buffered input logic for simultaneous updates via the LDSW command and offers hardware reset functionality. Packaged in a 32-lead LFCSP (5 mm × 5 mm), it is qualified for automotive applications and operates within a temperature range of −40°C to +125°C.

Feature Summary

• I²C-compatible serial interface supporting standard, fast, and high-speed modes
• Double-buffered input logic enabling simultaneous update of multiple switches
• Hardware reset capability ensuring all switches default to off state on power-up
• Automotive qualification for extended temperature operation

Applications

• AV switching in television systems
• Automotive infotainment routing
• CCTV signal distribution
• Ultrasound imaging equipment
• KVM switching matrices

Procurement Notes

Verify the specific suffix against the manufacturer's current ordering guide to confirm package type and temperature grade. Ensure the I²C bus voltage levels match the VL pin requirements. Confirm that the selected variant meets the required automotive reliability standards if applicable to the design.

Selection Notes

Select this component when a high-density matrix of bidirectional analog switches is required. The Y version is necessary for applications demanding operation up to +125°C. Consider the maximum on-resistance specifications at the intended supply voltage and signal level to ensure signal integrity. Verify that the I²C address pins allow for the required number of devices on a single bus.

Part Context

This part belongs to the ADG2128 family of analog crosspoint switches from Analog Devices. It provides a flexible interconnection matrix controlled via a digital serial interface. The family is designed for applications requiring complex signal routing between multiple inputs and outputs without manual intervention.

Replacement Considerations

Check the official datasheet for listed similar parts. Direct replacements must maintain the 8x12 configuration, I²C control, and compatible operating voltage ranges. Verify pinout compatibility if substituting directly into an existing footprint.
