Analog Devices Inc. AD8063ARZ-REEL7

Overview

AD8063ARZ-REEL7 from Analog Devices is a single-channel, rail-to-rail output voltage-feedback operational amplifier with 300 MHz −3 dB bandwidth (G = 1, VS = 3 V), 650 V/µs slew rate, and integrated power-down disable pin. It operates from 2.7 V to 8 V supplies, delivers ±50 mA output current, and achieves 0.01% differential gain / 0.04° differential phase error into 150 Ω - making it suitable for professional video signal conditioning and high-speed ADC driver applications.

For engineers reviewing the AD8063ARZ-REEL7 datasheet, AD8063ARZ-REEL7 pinout, AD8063ARZ-REEL7 application, or AD8063ARZ-REEL7 equivalent, key selection considerations include its 35 ns settling time to 0.1%, 400 µA quiescent current in disabled state, rail-to-rail output swing (0.1 V to 4.86 V on 5 V supply), and SOIC-8 package compatibility with space-constrained portable designs.

Technical Context

The AD8063ARZ-REEL7 uses a true single-supply voltage-feedback architecture with a high-slew-rate input stage capable of sensing signals down to 200 mV below the negative rail. Its rail-to-rail output stage employs a common-emitter topology that maintains low saturation voltage (25 mV + IO × 8 Ω) under load.

It supports unity-gain stability, exhibits 8.5 nV/√Hz input voltage noise at 100 kHz, and delivers 0.1 dB gain flatness to 30 MHz - critical for NTSC/PAL video buffering. The dedicated DISABLE pin enables fast turn-off (300 ns) and turn-on (40 ns) transitions, reducing supply current from 6.8 mA to 400 µA.

FAQ

What is the maximum supply voltage for AD8063ARZ-REEL7?

The absolute maximum supply voltage for AD8063ARZ-REEL7 is 8 V, as specified in the Absolute Maximum Ratings table. Continuous operation above this voltage risks permanent damage. For reliable long-term use, Analog Devices recommends staying within the operational range of 2.7 V to 8 V, with typical evaluation performed at 3 V, 5 V, and ±2.5 V supplies. Exceeding 8 V violates the device's internal power dissipation limits and may trigger latch-up.

Does AD8063ARZ-REEL7 support rail-to-rail input?

AD8063ARZ-REEL7 does not support rail-to-rail input. Its input common-mode voltage range is −0.2 V to +3.2 V with VS = 5 V - meaning it accepts signals 200 mV below ground but only up to 1.8 V below the positive rail. This limitation is explicitly documented in the Input Characteristics section. For true rail-to-rail input capability, consider alternatives like the ADA4807-1, which specifies −0.1 V to +5.1 V input range on 5 V supply.

Can AD8063ARZ-REEL7 drive a 150 Ω video load?

Yes, AD8063ARZ-REEL7 is explicitly characterized for 150 Ω video loads in the Applications and Specifications sections. It delivers 0.01% differential gain error and 0.04° differential phase error into 150 Ω at G = 2, meeting broadcast video standards. Output voltage swing is specified as 0.1 V to 4.75 V (min) under these conditions, and the amplifier sustains 30 MHz 0.1 dB flatness - confirming robust 150 Ω drive capability for RGB, YPbPr, and composite video paths.

What is the DISABLE pin logic level threshold for AD8063ARZ-REEL7?

The DISABLE pin of AD8063ARZ-REEL7 has defined logic thresholds: it asserts disable (high-impedance output, 400 µA I_Q) when voltage is ≤2.8 V, and enables normal operation when voltage is ≥3.2 V - tested at VS = 5 V. These values scale with supply voltage; at VS = 3 V, thresholds are ≤0.8 V (disable) and ≥1.2 V (enable). The transition occurs within 40 ns turn-on and 300 ns turn-off times, enabling precise timing control in synchronized systems.

Is AD8063ARZ-REEL7 unity-gain stable?

Yes, AD8063ARZ-REEL7 is unity-gain stable. The datasheet confirms stability in G = +1 configuration across all supply voltages (2.7 V to 8 V) and load conditions (1 kΩ, 150 Ω, and capacitive loads up to 300 pF with series resistance). Figure 10 shows flat small-signal response at G = +1, and the General Description states "unity-gain stable" explicitly. No external compensation is required for stable operation at G = 1, simplifying design in video buffer and follower applications.
