Analog Devices Inc. AD810AR-REEL

Overview

AD810AR-REEL from Analog Devices is a current-feedback video operational amplifier optimized for composite and HDTV signal processing. It delivers 80 MHz −3 dB bandwidth (G = +1), 30 MHz 0.1 dB bandwidth (G = +2), 0.02% differential gain, and 0.04° differential phase at ±15 V - enabling broadcast-quality NTSC/PAL video line driving and ADC/DAC buffering in professional cameras and multimedia systems.

For engineers reviewing the AD810AR-REEL datasheet, AD810AR-REEL pinout, AD810AR-REEL application, or AD810AR-REEL equivalent, key selection criteria include disable-mode power-down current (2.1 mA), input voltage noise (2.9 nV/√Hz), output swing into 150 Ω (±2.9 V at ±5 V supplies), and guaranteed break-before-make disable timing (100 ns turn-off).

Technical Context

The AD810AR-REEL implements a high-speed current-feedback architecture where closed-loop bandwidth depends primarily on feedback resistor value-not gain-enabling stable 65–80 MHz bandwidth across G = ±1 to ±10 configurations. Its transimpedance design maintains wide dynamic range with low 2.9 nV/√Hz input voltage noise and 13 pA/√Hz inverting-input current noise.

It features a dedicated active-low DISABLE pin that guarantees break-before-make switching, achieves 64 dB off-state input-to-output isolation at 5 MHz, and reduces quiescent supply current from 8.0 mA to 2.1 mA. Operation is specified across ±5 V to ±15 V dual supplies, with input common-mode range extending to ±13 V at ±15 V rails.

Key Specifications

FAQ

What is the recommended feedback resistor for AD810AR-REEL at G = +2 with ±15 V supplies?

The AD810AR-REEL datasheet specifies a 715 Ω feedback resistor (RF) for G = +2 with ±15 V supplies to achieve 75 MHz −3 dB bandwidth and <0.1 dB gain peaking. This value is validated in Table 5 and Figure 24. Using 1% tolerance metal-film resistors ensures consistent flatness across production units. The AD810AR-REEL's current-feedback architecture makes bandwidth highly dependent on RF value, so deviation directly impacts frequency response.

Does AD810AR-REEL support single-supply operation?

No, the AD810AR-REEL is designed exclusively for dual-supply operation across ±2.5 V to ±18 V. Its input common-mode range extends to ±13 V at ±15 V rails but does not include ground-referenced operation. Single-ended input signals require level-shifting circuitry or biasing networks to stay within the specified ±2.5 V to ±13 V common-mode window. The AD810AR-REEL lacks rail-to-rail input or output capability.

How does the DISABLE pin function on AD810AR-REEL, and what drive strength is required?

The DISABLE pin on AD810AR-REEL is active-low and requires sinking ≥30 µA to guarantee disable (per Table 1). At ±15 V supplies, it draws up to 400 µA when pulled to 0 V. The internal circuit ensures break-before-make switching with 100 ns typical turn-off time and 170 ns turn-on time. A standard CMOS gate or microcontroller GPIO can drive it directly; no external pull-up is needed as the pin is internally biased.

Can AD810AR-REEL drive a 75 Ω back-terminated coaxial cable directly?

Yes, the AD810AR-REEL is explicitly characterized driving 150 Ω loads - equivalent to one 75 Ω cable with 75 Ω back-termination - as stated in the General Description and Table 1. It delivers ±2.9 V output swing into 150 Ω at ±5 V supplies and maintains 0.02% differential gain/0.04° phase under this load. For longer cables or multiple taps, verify stability with proper PCB layout and 0.1 µF supply bypassing per the datasheet's Figure 45 reference design.

What is the thermal performance limit for continuous operation of AD810AR-REEL in SOIC-8 package?

The AD810AR-REEL in SOIC-8 (R-8 package) has a junction-to-ambient thermal resistance (θ_JA) of 150°C/W under natural convection (Table 3). With max 8.0 mA quiescent current at ±15 V (120 mW dissipation), ambient temperature must remain ≤+75°C to keep junction temperature below the 145°C limit for the AD810A grade. Derating curves in Figure 2 confirm ≤1.2 W total power at +85°C ambient - requiring heatsinking or airflow for sustained high-output operation.
