Analog Devices Inc. AD8023AR-REEL

Overview

AD8023AR-REEL from Analog Devices is a triple current-feedback video operational amplifier optimized for RGB and component video line driving. It delivers 70 mA output current per channel, 250 MHz unity-gain bandwidth, and 0.06% differential gain error at 3.58 MHz-enabling high-fidelity analog video signal distribution in LCD displays and broadcast equipment.

For engineers reviewing the AD8023AR-REEL datasheet, AD8023AR-REEL pinout, AD8023AR-REEL application, or AD8023AR-REEL equivalent, key selection criteria include capacitive load drive capability (up to 1000 pF), high-speed disable function (30 ns turn-off), rail-to-rail output swing (within 1 V of rails), and industrial temperature range (–40°C to +85°C).

Technical Context

The AD8023AR-REEL implements a current-feedback architecture with three independent amplifiers, each featuring 75 Ω inverting input resistance and 100 kΩ noninverting input resistance. Its open-loop transresistance is 111 kΩ (typ), supporting stable closed-loop gains ≥1 with feedback resistors from 250 Ω to 2 kΩ.

Each channel integrates a dedicated disable pin enabling high-impedance output state with 12 pF off-capacitance and –70 dB off-isolation at 6 MHz. The device operates on ±2.5 V to ±7.5 V dual supplies or +4.2 V to +15 V single supply, drawing 7.0 mA per amplifier (typ) in active mode and 1.3 mA (typ) in power-down.

Key Specifications

FAQ

What is the maximum capacitive load the AD8023AR-REEL can drive stably?

The AD8023AR-REEL is specified to drive up to 1000 pF capacitively without oscillation when used with appropriate feedback and series resistors. Data Sheet Table II recommends RS = 10 Ω and RF = 3 kΩ for loads ≥500 pF at G ≥ 2. At 300 pF, it achieves 0.1% settling in 35 ns with RS = 16.9 Ω and RF = 750 Ω, confirming robust high-frequency stability in real-world video cabling scenarios. This capability is intrinsic to its current-feedback architecture and high short-circuit current (300 mA).

Does the AD8023AR-REEL support single-supply operation?

Yes, the AD8023AR-REEL operates from a single supply of +4.2 V to +15 V, as confirmed in the Absolute Maximum Ratings and Power Supply sections of the datasheet. When used in single-supply mode, the input common-mode voltage range extends to within 6.0 V of either rail, and output swing reaches within 1.3 V of ground (VOL) and within 1.3 V of VCC (VOH) into 150 Ω. This allows direct interfacing with 5 V or 12 V video systems without level-shifting circuitry.

How does the disable function affect output impedance in the powered-down state?

When any DISABLE pin is asserted, the corresponding amplifier's output enters a high-impedance state with 12 pF off-capacitance (typ) and –70 dB isolation at 6 MHz. The effective output impedance approximates a 1.5 kΩ resistor (sum of feedback and gain resistors) in parallel with that 12 pF capacitance-verified in the Disable Mode Operation section. This prevents loading of downstream circuits during channel blanking or power gating, critical for video multiplexing applications using the AD8023AR-REEL.

What is the differential phase error specification for the AD8023AR-REEL, and under what conditions is it measured?

The AD8023AR-REEL exhibits 0.02° differential phase error at 3.58 MHz, measured with RL = 150 Ω, G = +2, and RFB = 750 Ω, as stated in the AD8023–SPECIFICATIONS table. This value reflects the device's ability to maintain precise timing alignment between luminance and chrominance components in NTSC video systems. The low phase error stems from its current-feedback topology and wide phase margin, ensuring minimal color shift across the broadcast video band.

Is the AD8023AR-REEL pin-compatible with earlier revisions like AD8023AR?

Yes, the AD8023AR-REEL shares identical pinout, electrical specifications, and package (14-lead SOIC R-14) with the AD8023AR. The "-REEL" suffix denotes tape-and-reel packaging for automated assembly; all functional and mechanical characteristics-including disable pin behavior, bandwidth, and output drive-are fully consistent with the base AD8023AR part number. No PCB layout changes are required when migrating from AD8023AR to AD8023AR-REEL.
