ADG2108YCPZ-HS-RL7

Overview

The ADG2108YCPZ-HS-RL7 is an I2C-compatible CMOS analog crosspoint switch featuring an 8 × 10 unbuffered array with 80 bidirectional channels. It supports standard, fast, and high-speed (3.4 MHz) I2C interfaces for addressing and configuration. The device operates on dual ±5 V or single +12 V supplies, offering a maximum on-resistance of 35 Ω and low quiescent current under 20 µA. It provides up to 300 MHz bandwidth, simultaneous switch updates via the LDSW command, and a power-on reset function. Packaged in a 32-lead LFCSP_WQ (5 mm × 5 mm), it functions within an automotive temperature range of −40°C to +125°C.

Feature Summary

• I2C-compatible serial interface supporting standard, fast, and high-speed modes
• Bidirectional 8 × 10 analog switch array with individual channel addressing
• Simultaneous update capability for multiple switches using the LDSW command
• Power-on reset ensures all switches initialize to the off state

Applications

• AV switching in TV systems
• Automotive infotainment
• CCTV surveillance
• Test equipment and instrumentation

Procurement Notes

Verify the -HS suffix indicates high-speed I2C support. Confirm the Y variant meets the extended temperature requirement. Check package orientation and pin 1 marking against the LFCSP_WQ outline dimensions. Ensure ESD precautions are applied during handling due to sensitivity.

Selection Notes

Select this model when high-speed I2C communication at 3.4 MHz is required. The Y version is necessary for applications operating above 85°C. Verify that the 35 Ω maximum on-resistance fits the signal integrity requirements. Ensure the 32-lead LFCSP_WQ footprint matches the PCB layout constraints.

Part Context

This component belongs to the ADG2108 family of analog crosspoint switches. The -HS suffix denotes support for the high-speed I2C interface option. The Y suffix specifies the automotive temperature grade. It shares the same core architecture as the B version but offers enhanced thermal performance and faster serial communication capabilities.

Replacement Considerations

The ADG2108B is a compatible alternative if high-speed I2C is not required. Both share identical pinouts and electrical characteristics except for the serial interface speed and temperature range. Verify that the replacement part number matches the specific supply voltage and packaging requirements.
