AD8146ACPZ-R7

Overview

The AD8146ACPZ-R7 is a triple differential driver for wideband video applications, manufactured by Analog Devices Inc. It features a fixed gain of 2 V/V and operates within a supply voltage range of +4.5 V to ±5.5 V. The device provides a large signal bandwidth of 700 MHz at 2 V p-p and a small signal bandwidth of 900 MHz. Key electrical parameters include a slew rate of 3000 V/µs, an output balance error of -50 dB at 50 MHz, and a quiescent current of 58 mA per positive supply rail. It utilizes a 24-lead LFCSP package.

Feature Summary

• Triple high-speed fully differential driver architecture with internal common-mode feedback for balanced outputs
• Adjustable output common-mode voltage control via dedicated VOCM pins for each channel
• Output pull-down feature enabling line isolation and differential multiplexing capabilities
• Supports single-ended to differential conversion or differential-to-differential reception

Applications

• QXGA or 1080p video transmission systems
• KVM networking infrastructure
• Video transmission over unshielded twisted pair (UTP) cables
• Differential signal multiplexing

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the component matches the AD8146 variant with Gain = 2, distinct from AD8147 or AD8148. Ensure the LFCSP-24 package type aligns with board layout requirements. Check for moisture sensitivity levels and storage conditions prior to assembly.

Selection Notes

Select this component for designs requiring three independent differential channels with adjustable common-mode levels. It is suitable for driving Category 5 UTP cables or PCB transmission lines. Consider the 700 MHz large signal bandwidth and 3000 V/µs slew rate for high-resolution video signals. Verify power supply constraints fit the +4.5 V to ±5.5 V operating range.

Part Context

This part belongs to the AD8146/AD8147/AD8148 family of triple differential drivers designed for high-speed analog signal processing. Manufactured on Analog Devices' second-generation XFCB bipolar process, these devices are optimized for wideband video applications. The AD8146 specifically offers adjustable common-mode control, differentiating it from the sync-on-common-mode variants in the series.
