Analog Devices Inc. AD8013ARZ-14-RL

Overview

AD8013ARZ-14-RL 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 (±5 V), 0.02% differential gain error, 0.06° differential phase error at 3.58 MHz, and 18 ns settling time (0.1%) into 150 Ω - enabling broadcast-grade video line driving in LCD displays and professional video equipment.

For engineers reviewing the AD8013ARZ-14-RL datasheet, AD8013ARZ-14-RL pinout, AD8013ARZ-14-RL application, or AD8013ARZ-14-RL equivalent, key selection criteria include its triple-channel disable function (30 ns turn-off), ±5 V / +5 V supply flexibility, capacitive load drive up to 1000 pF, and matching performance (0.1 dB gain flatness match at 20 MHz) critical for multi-channel timing alignment.

Technical Context

The AD8013ARZ-14-RL implements a proprietary current-feedback architecture with 150 Ω inverting input resistance and >800 kΩ open-loop transresistance, enabling stable closed-loop operation across gains ≥1 using discrete feedback resistors. Its high output short-circuit current (95 mA) and rail-to-rail output swing (within 1.3 V of rails into 150 Ω) support fast slewing (1000 V/µs) and large-signal integrity.

Each channel features independent high-speed disable logic referenced to –VS, with 1.3–1.9 V switching threshold, 30 ns turn-off, and >70 dB off-isolation at 6 MHz. The device maintains <0.1 dB gain flatness to 60 MHz (G = +2, RL = 150 Ω) and achieves <0.05% differential gain error under NTSC/PAL conditions - confirming suitability for analog video signal chains requiring broadcast compliance.

FAQ

What supply voltage ranges does the AD8013ARZ-14-RL support?

The AD8013ARZ-14-RL operates from a single +4.2 V to +13 V supply or dual ±2.1 V to ±6.5 V supplies. At ±5 V, typical quiescent current is 3.4–4.0 mA per amplifier. The device maintains specified video performance (0.02% differential gain, 140 MHz bandwidth) across this full range, enabling flexible system-level power architecture design without performance trade-offs.

How does the AD8013ARZ-14-RL achieve broadcast-compliant differential gain and phase?

The AD8013ARZ-14-RL achieves 0.02% differential gain error and 0.06° differential phase error at 3.58 MHz (NTSC) through proprietary current-feedback topology optimization, matched internal transistor pairs, and low-input-bias-current design (2–10 µA). These characteristics are measured under standard conditions (RL = 150 Ω, G = +2, ±5 V supply) and meet SMPTE RP 168 requirements for professional video signal chains.

Can the AD8013ARZ-14-RL drive 75 Ω video lines directly?

Yes - the AD8013ARZ-14-RL is explicitly characterized for 150 Ω back-terminated loads (standard for component video), and its 30 mA output current per channel supports direct drive of 75 Ω lines when configured in gain-of-2 mode with appropriate feedback network (e.g., RF = 845 Ω, RG = 845 Ω per Figure 31). Output swing remains within 1.3 V of rails, preserving 1 Vpp video headroom.

What is the maximum capacitive load the AD8013ARZ-14-RL can drive stably?

The AD8013ARZ-14-RL is specified to drive up to 1000 pF capacitively without oscillation when used with appropriate feedback resistor values (e.g., RF = 6 kΩ for G = +2, RS = 15 Ω per Table II). This capability eliminates external isolation resistors in long-trace or cable-drive applications, and is validated by pulse response testing (Figure 29 shows clean 300 pF step response with no overshoot).

How does the per-channel disable function work in the AD8013ARZ-14-RL?

Each DISABLE pin (1, 2, 3) controls one amplifier independently. Pulling the pin to >1.3 V above –VS places that channel in high-impedance shutdown with 30 ns turn-off time, 70 dB input-to-output isolation at 6 MHz, and quiescent current reduced to 0.3–0.4 mA. Floating the pin leaves the amplifier enabled. This enables precise timing control in 3:1 video multiplexers and dynamic power management in multi-source systems.
