AD8147ACPZ-R2

Overview

The AD8147ACPZ-R2 is a high-speed triple differential driver designed for wideband video applications. It converts differential or single-ended inputs to differential outputs with a fixed gain of 2 V/V. The device features a 600 MHz large signal bandwidth and a 3000 V/μs slew rate. It operates on supply voltages ranging from +5 V to ±5 V, drawing approximately 61.5 mA at ±5 V. Key features include internal common-mode feedback, sync-on-common-mode encoding, and an output pull-down feature for line isolation.

Feature Summary

• Integrates three fully differential drivers with fixed gain of 2 V/V
• Encodes vertical and horizontal sync signals onto output common-mode voltages
• Includes output pull-down capability for series diode-based line isolation
• Utilizes internal common-mode feedback for balanced amplitude and phase

Applications

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

Procurement Notes

Verify the specific suffix 'R2' against manufacturer documentation to confirm reel packaging specifications. Ensure the component matches the LFCSP-24 package outline dimensions. Confirm that the operating temperature range meets system requirements of -40°C to +85°C. Cross-reference the datasheet revision to validate electrical parameters.

Selection Notes

Select this component when a fixed gain of 2 V/V is required for triple-channel differential driving. It is suitable for applications requiring sync-on-common-mode encoding without external circuitry. Consider the AD8146 if adjustable output common-mode voltage is needed instead of encoded sync signals. Evaluate power consumption constraints relative to the specified quiescent current.

Part Context

This part belongs to the AD8146/AD8147/AD8148 family of triple differential drivers manufactured by Analog Devices. While the AD8146 offers adjustable common-mode voltage and the AD8148 provides a fixed gain of 4, the AD8147 specifically integrates sync-on-common-mode encoding. All variants share similar high-speed performance characteristics and package types.

Replacement Considerations

The AD8146ACPZ serves as a functional substitute where adjustable common-mode voltage is preferred over sync encoding. The AD8148ACPZ is an alternative when a higher fixed gain of 4 V/V is required. Verify pin compatibility and thermal resistance specifications before substitution.
