Analog Devices Inc. AD8003ACPZ-R2

Overview

AD8003ACPZ-R2 from Analog Devices is a triple, ultrahigh-speed current-feedback operational amplifier optimized for demanding video and high-frequency signal conditioning. It delivers 1.5 GHz small-signal bandwidth (G = +1, ±5 V), 4300 V/µs slew rate, and 0.1% settling in 12 ns - enabling QXGA-resolution RGB video driver applications with 0.05% differential gain error and 0.01° differential phase error at RL = 150 Ω.

For engineers reviewing the AD8003ACPZ-R2 datasheet, AD8003ACPZ-R2 pinout, AD8003ACPZ-R2 application, or AD8003ACPZ-R2 equivalent, this page provides verified technical context, validated pin functions, real-world video and instrumentation use cases, and two confirmed alternative parts with documented functional trade-offs.

Technical Context

The AD8003ACPZ-R2 implements a current-feedback architecture using Analog Devices' proprietary XFCB process, enabling wideband operation without sacrificing dc precision. Its transimpedance gain stage drives three independent amplifiers, each with dedicated power-down control, noninverting/inverting inputs, feedback terminals, and rail-to-rail output capability into 150 Ω loads.

Each amplifier supports ±5 V or single +5 V supply operation, with independent power-down pins reducing quiescent current per channel from 9.5 mA to 1.6 mA. The 24-lead LFCSP_WQ package integrates an exposed paddle for thermal management and features ADI's low-distortion pinout - physically separating +IN from −VS to suppress second-harmonic generation and routing feedback directly between FEEDBACK and −IN pins to minimize parasitics.

Key Specifications

Pinout & Package

FAQ

What is the maximum small-signal bandwidth of the AD8003ACPZ-R2 under ±5 V supply conditions?

The AD8003ACPZ-R2 achieves a maximum small-signal bandwidth of 1650 MHz at G = +1 with ±5 V supplies, as specified in Table 1 of the Rev. C datasheet. This bandwidth is measured with 0.2 V p-p output swing and 432 Ω feedback resistor. At G = +2, bandwidth drops to 730 MHz - a characteristic inherent to current-feedback topology where bandwidth scales inversely with closed-loop gain.

Does the AD8003ACPZ-R2 support single +5 V supply operation?

Yes, the AD8003ACPZ-R2 operates with a single +5 V supply, delivering 1050 MHz bandwidth at G = +1 and 590 MHz at G = +2 (Table 2). Input common-mode voltage range is 1.3 V to 3.7 V, and output swing reaches ±1.62 V into 150 Ω. Power-down functionality remains fully operational, reducing quiescent current per channel to 0.9 mA typical.

How does the AD8003ACPZ-R2's low-distortion pinout improve video performance?

The AD8003ACPZ-R2's low-distortion pinout physically separates +IN pins from −VS pins and adds dedicated FEEDBACK terminals - reducing second-harmonic distortion by minimizing coupling between high-impedance input nodes and noisy supply rails. This layout directly enables the 0.05% differential gain and 0.01° differential phase error required for NTSC video compliance.

What is the purpose of the exposed paddle on the AD8003ACPZ-R2 LFCSP package?

The exposed paddle on the AD8003ACPZ-R2 lowers thermal resistance to θJA = 70°C/W - approximately 40% better than standard SOIC packages. When soldered to a PCB ground plane with thermal vias, it dissipates heat from the 100 mA output stage efficiently, ensuring reliable operation at +85°C ambient and preventing parametric shift due to junction temperature rise.

Can the AD8003ACPZ-R2 drive 75 Ω video loads directly?

Yes - the AD8003ACPZ-R2 is explicitly characterized driving 150 Ω loads (equivalent to two 75 Ω terminations in parallel), delivering 0.05% differential gain error and 0.01° differential phase error per NTSC standards. For direct 75 Ω source termination, use series 75 Ω resistors at each output (as shown in Figure 40) to match cable impedance and prevent reflections.
