Analog Devices Inc. AD8013AR-14

Overview

AD8013AR-14 from Analog Devices is a single-supply, low-power, triple current-feedback video amplifier optimized for RGB and component video signal conditioning. It delivers 140 MHz unity-gain bandwidth, 0.02% differential gain error, and 0.06° differential phase error at 3.58 MHz into 150 Ω, enabling broadcast-grade video line driving in LCD displays and professional video equipment.

For engineers reviewing the AD8013AR-14 datasheet, AD8013AR-14 pinout, AD8013AR-14 application, or AD8013AR-14 equivalent, key selection criteria include its per-channel disable function (30 ns turn-off), ±5 V / +5 V supply flexibility, 18 ns settling time (0.1%), and SOIC-14 industrial-temperature packaging for space-constrained video routing designs.

Technical Context

The AD8013AR-14 implements a proprietary current-feedback architecture with 150 Ω inverting input resistance and >800 kΩ open-loop transresistance, enabling stable high-speed operation across gain configurations ≥+1. Its 12 Ω closed-loop output resistance and 95 mA short-circuit current support robust capacitive load drive up to 1000 pF without oscillation.

Each of the three independent amplifiers features dedicated disable pins (DISABLE 1–3) referenced to –VS, with 1.3–1.9 V switching threshold and 70 dB off-isolation at 6 MHz. Gain flatness is maintained to 60 MHz (0.1 dB) under ±5 V supply, while differential gain/phase performance remains specified only for RL = 150 Ω at +5 V and ±5 V conditions.

Key Specifications

Pinout & Package

AD8013AR-14 is housed in a 14-pin plastic SOIC (R-14) package with standard JEDEC MS-012AC footprint (5.0 mm × 4.4 mm body, 1.27 mm pitch). Thermal resistance θ_JA = 120°C/W.

FAQ

What supply voltage ranges does the AD8013AR-14 support?

The AD8013AR-14 operates on a single +4.2 V to +13 V supply or dual ±2.1 V to ±6.5 V supplies. At +5 V single supply, it delivers 125 MHz bandwidth and 0.05% differential gain error; at ±5 V, bandwidth increases to 140 MHz with improved 0.02% differential gain error. The device requires connection to both +VS and –VS pins even in single-supply configurations to maintain internal bias stability.

How does the AD8013AR-14 achieve stable operation with large capacitive loads?

The AD8013AR-14 achieves stable operation with up to 1000 pF capacitive loads through its high open-loop transresistance (>800 kΩ) and low inverting input bias current (<10 µA), which minimize gain errors when using large feedback resistors. Its 95 mA short-circuit current enables rapid slewing on large capacitors, and recommended external series resistors (e.g., 15 Ω for 300 pF loads) suppress ringing without compromising bandwidth.

What is the purpose of the DISABLE pins on the AD8013AR-14?

The DISABLE 1–3 pins on the AD8013AR-14 provide per-channel power-down control: pulling any pin ≥1.6 V above –VS disables the corresponding amplifier, reducing its quiescent current to 0.3–0.4 mA and placing its output in high-impedance state with 70 dB input-to-output isolation at 6 MHz. This enables video multiplexing and power gating without external switches, with 30 ns turn-off and 50 ns turn-on times.

Can the AD8013AR-14 be used in RGB video systems with 75 Ω termination?

Yes, the AD8013AR-14 is explicitly characterized for 150 Ω loads but functions reliably with 75 Ω terminations common in RGB video. At G = +2 and RL = 75 Ω, it maintains 0.1 dB gain flatness to 50 MHz and differential phase error <0.12°, meeting SMPTE 253M requirements. Output swing remains within 1.3 V of rails, accommodating standard 1 V_PP video levels with adequate headroom.

What is the operating temperature range for the AD8013AR-14?

The AD8013AR-14 is rated for industrial temperature operation from –40°C to +85°C, validated across all specifications including differential gain/phase error, bandwidth, and disable timing. This range covers typical environments for professional video equipment, medical imaging displays, and industrial HMIs where ambient temperatures exceed commercial limits.
