AD8146ACPZ-R2

Overview

The AD8146ACPZ-R2 is a triple differential driver for wideband video applications. It features a 700 MHz -3 dB large signal bandwidth and a 900 MHz small signal bandwidth. The device provides a fixed gain of 2 V/V with a slew rate of 3000 V/µs. It operates on a supply voltage range of +4.5 V to ±5.5 V, drawing 58 mA of quiescent current. The component is housed in a 24-lead LFCSP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Triple high-speed fully differential driver architecture
• Internal common-mode feedback network for output balance
• Adjustable output common-mode voltage control
• Output pull-down feature for line isolation

Applications

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

Procurement Notes

Verify the specific suffix R2 against official documentation to confirm reel packaging specifications. Ensure compatibility with the 24-lead LFCSP_WQ footprint. Confirm that the fixed gain of 2 matches the design requirements, distinguishing it from other variants in the series. Validate thermal management needs for the exposed paddle connection.

Selection Notes

Select this component when a fixed gain of 2 is required for triple-channel differential driving. Compare performance against the AD8147 and AD8148 if different gain levels or sync encoding features are needed. Consider the adjustable common-mode voltage capability for flexible signal transmission setups requiring precise level shifting.

Part Context

This part belongs to the AD8146/AD8147/AD8148 family of triple differential drivers manufactured by Analog Devices. These devices are designed for high-resolution component video signals and utilize the second-generation XFCB bipolar process. They are intended for use with receivers like the AD8145 and crosspoint switches such as the AD8117.
