AD8146ACPZ-RL

Overview

The AD8146ACPZ-RL is a triple differential driver for wideband video applications. It features a fixed gain of 2 V/V and supports differential or single-ended inputs to differential outputs. Key electrical parameters include a 700 MHz large signal bandwidth, 3000 V/μs slew rate, and 57 mA quiescent current at ±5 V. The device operates on supply voltages ranging from +4.5 V to ±5.5 V and is housed in a 24-lead LFCSP package.

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 'ACPZ-RL' against the manufacturer's ordering guide to confirm the reel packaging and temperature grade. Ensure the design accommodates the exposed paddle thermal requirements by connecting it to a ground plane. Confirm that the application circuit respects the absolute maximum ratings for supply voltage and power dissipation to maintain device reliability.

Selection Notes

Select this component when a fixed gain of 2 is required for driving RGB video signals. It is suitable for designs needing adjustable common-mode levels unlike the sync-on variants. Consider the 24-lead LFCSP footprint for space-constrained PCB layouts. Verify compatibility with the intended UTP cable impedance and receiver input specifications.

Part Context

This part belongs to the AD8146/AD8147/AD8148 family of triple differential drivers manufactured on Analog Devices' second-generation XFCB bipolar process. While the AD8147 and AD8148 offer sync-on-common-mode encoding, the AD8146 provides flexible common-mode voltage adjustment for general-purpose analog signal transmission over differential lines.

Replacement Considerations

The AD8147ACPZ-RL and AD8148ACPZ-RL are pin-compatible members of the same family. Substitution requires accounting for differences in gain (fixed at 4 for AD8148) and the presence of sync-on-common-mode encoding features in those variants which are absent in the AD8146.
