Product details
Overview
AD8023ARZ-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 broadcast-grade analog video signal conditioning in LCD displays and professional video equipment.
For engineers reviewing the AD8023ARZ-REEL datasheet, AD8023ARZ-REEL pinout, AD8023ARZ-REEL application, or AD8023ARZ-REEL equivalent, key selection criteria include capacitive load drive capability (up to 1000 pF), high-speed disable timing (30 ns turn-off), rail-to-rail output swing (within 1 V of rails), and triple-channel matching performance for synchronized video paths.
Technical Context
The AD8023ARZ-REEL implements a current-feedback architecture with 75 Ω inverting input impedance and 100 kΩ noninverting input resistance, enabling stable wideband operation across closed-loop gains ≥1. Its transimpedance open-loop gain exceeds 111 kΩ, supporting flat 0.1 dB gain response up to 7 MHz at G = +3.
Each of the three amplifiers features independent high-speed disable control with 1.6 V threshold referenced to –VS, 12 pF off-state output capacitance, and –70 dB off-isolation at 6 MHz - allowing dynamic channel muting in video multiplexing without signal coupling or settling penalties.

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6738MA/NOPB | Higher 375 MHz bandwidth but only 45 mA output current; no integrated disable function | Lacks per-channel shutdown - unsuitable for video multiplexing or power-gated designs | Choose when maximum small-signal bandwidth is critical and disable functionality is unnecessary |
| THS3203D | Lower 190 MHz bandwidth; 110 mA output current; requires external disable logic | Higher output current but larger 16-pin SOIC package and no native disable pins | Prefer when driving heavier loads (>200 mA) and board space allows larger footprint |
Compared with LMH6738MA/NOPB and THS3203D, the AD8023ARZ-REEL uniquely combines 250 MHz bandwidth, 70 mA drive, and integrated 30 ns disable in a compact SOIC-14 - making it optimal for space-constrained, multi-channel video routing where dynamic channel control is required.

FAQ
What is the maximum capacitive load the AD8023ARZ-REEL can drive stably?
The AD8023ARZ-REEL is characterized to drive up to 1000 pF capacitive load without oscillation when used with appropriate feedback and series resistors. Data Sheet Table II specifies RS = 10 Ω and RF = 3 kΩ for CL ≥ 500 pF at G = +2. This capability eliminates external isolation components in video trace compensation, and the AD8023ARZ-REEL maintains 35 ns 0.1% settling even at 300 pF.
Does the AD8023ARZ-REEL support single-supply operation?
Yes, the AD8023ARZ-REEL operates from a single supply of +4.2 V to +15 V, with input common-mode range extending to ±6.0 V and output swing within 1.0 V of either rail. When powered from +5 V, the device delivers full video signal swing (e.g., 0.3–2.0 V for CVBS) with 0.06% differential gain error - confirmed in Figure 7 and Specifications Table.
How does the disable function affect power consumption of the AD8023ARZ-REEL?
When any DISABLE pin is asserted, the corresponding amplifier reduces quiescent current from 10.0 mA (max) to 1.3–4.0 mA, as specified in the Power Supply section. With all three channels disabled, total supply current drops below 12 mA - enabling dynamic power scaling in video systems during blanking intervals or standby modes without compromising channel isolation.
What is the differential phase error specification for the AD8023ARZ-REEL at PAL frequency?
The AD8023ARZ-REEL achieves 0.02° differential phase error at 4.43 MHz (PAL chroma subcarrier), matching its 0.02° spec at 3.58 MHz (NTSC). This value is measured under RL = 150 Ω, G = +2, RFB = 750 Ω conditions and ensures accurate hue reproduction across both major analog TV standards - critical for multistandard broadcast equipment.
Can the AD8023ARZ-REEL be used in inverting configuration?
Yes, the AD8023ARZ-REEL supports stable inverting configurations with gains ≥1. Table I lists –1 and –10 closed-loop gains with verified bandwidths (150 MHz and 60 MHz respectively at ±7.5 V). The current-feedback architecture ensures consistent slew rate and settling performance regardless of inverting/noninverting topology - confirmed in Figures 20, 26, and 30.
