Product details
Overview
AD826ANZ from Analog Devices is a dual, high-speed, low-power voltage-feedback operational amplifier in an 8-lead PDIP package. It delivers 50 MHz unity-gain bandwidth, 350 V/µs slew rate, and 70 ns settling time to 0.01%, with ±5 V or +5 V single-supply operation - ideal for ADC/DAC buffering and video line driving.
For engineers reviewing the AD826ANZ datasheet, AD826ANZ pinout, AD826ANZ application, or AD826ANZ equivalent, key selection criteria include capacitive-load drive capability (unlimited), output current (50 mA min per amp), supply flexibility (+5 V to ±15 V), and dual-channel matching performance in instrumentation and data acquisition systems.
Technical Context
The AD826ANZ employs a degenerated NPN differential pair feeding a folded-cascode gain stage and class AB emitter-follower output buffer, enabling stable operation into heavy resistive and unlimited capacitive loads. Its internal compensation adapts dynamically to load capacitance via bootstrapped CF, preserving phase margin across varying CL.
It achieves precise dynamic matching: gain flatness match ≤0.2 dB at 40 MHz, slew rate match ≤10 V/µs, and crosstalk ≤–80 dB at 5 MHz. DC matching includes input offset voltage match ≤2 mV and CMRR match ≥80 dB over –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 50 MHz @ ±15 V - supports >20 MHz signal paths in video and data acquisition without instability. |
| Slew Rate | 350 V/µs @ ±15 V - enables clean 10 V step response in <70 ns for fast-settling ADC drivers. |
| Settling Time | 70 ns to 0.01% - meets timing budgets for 10 MSPS+ flash ADCs with 12-bit accuracy. |
| Output Current | 50 mA min per amplifier - drives 150 Ω video loads or parallel configurations up to 100 mA. |
| Input Offset Voltage | 2 mV max - ensures <0.5 LSB error in 10-bit systems with ±5 V full-scale range. |
| Supply Range | +5 V single or ±2.5 V to ±18 V dual - operates directly from logic rails or industrial supplies without level-shifting. |
| Capacitive Load Drive | Unlimited - eliminates external isolation resistors in cable driver and filter applications. |
Pinout & Package
AD826ANZ is housed in an 8-lead plastic mini-DIP (PDIP) package per JEDEC MS-001, with 0.300-inch body width and 0.100-inch lead pitch. Pin 1 is marked by a notch or dot; leads are straight and through-hole compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (V+) | Positive Supply | Accepts +5 V (single) or +15 V (dual); requires local 0.1 µF decoupling to ground. |
| 2 (OUT2) | Amplifier 2 Output | Delivers 50 mA into 150 Ω; supports rail-to-rail swing of ±3.6 V @ ±5 V supply. |
| 3 (–IN2) | Inverting Input 2 | Differential input node; input bias current 3.3–6.6 µA; requires balancing resistor for offset minimization. |
| 4 (+IN2) | Noninverting Input 2 | High-impedance input (300 kΩ); common-mode range extends to within 1.2 V of V– @ +5 V supply. |
| 5 (OUT1) | Amplifier 1 Output | Electrically identical to Pin 2; matched slew rate and gain flatness enable parallel or differential use. |
| 6 (–IN1) | Inverting Input 1 | Matches Pin 3; used with feedback network to set closed-loop gain and bandwidth. |
| 7 (+IN1) | Noninverting Input 1 | Matches Pin 4; supports single-ended or differential input configurations. |
| 8 (V–) | Negative Supply | Ground for +5 V operation; accepts –5 V or –15 V in dual-supply mode; must be decoupled. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD827ANZ | Higher quiescent current (12 mA/amp vs. 7.5 mA), 100 MHz GBW, but only specified for ±15 V operation. | Better for wideband RF IF stages; less suitable for +5 V portable systems due to supply inflexibility. | Select AD827ANZ when bandwidth >60 MHz is required and dual ±15 V supply is available. |
| LMH6622MF/NOPB | Lower input bias current (1.2 µA typ), 150 MHz GBW, but limited capacitive load drive (<100 pF recommended). | Preferred for precision photodiode amplification; unsuitable for direct 75 Ω cable driving without isolation. | Choose LMH6622MF/NOPB for low-noise, high-GBW applications where load capacitance is tightly controlled. |
Compared with AD826ANZ, AD827ANZ trades power efficiency for higher speed and reduced supply flexibility, while LMH6622MF/NOPB offers superior small-signal bandwidth at the cost of robust capacitive-load tolerance - making AD826ANZ uniquely balanced for general-purpose high-speed buffering with real-world load conditions.

FAQ
What supply voltages does the AD826ANZ support?
The AD826ANZ operates from a single +5 V supply or dual ±2.5 V to ±18 V supplies. At +5 V, it delivers 25 MHz bandwidth and ±3.5 V output swing into 150 Ω; at ±15 V, it achieves 50 MHz bandwidth and ±13.4 V swing. Quiescent current is 7.5 mA per amplifier across this full range, making AD826ANZ suitable for both battery-powered and industrial systems.
Does the AD826ANZ require external compensation for capacitive loads?
No, the AD826ANZ features internal adaptive compensation that supports unlimited capacitive loads without external components. Its output stage uses a bootstrapped capacitor (CF) that automatically adjusts effective compensation based on load capacitance, maintaining stability from 0 pF to >10 nF - a key advantage over most high-speed op amps that require series isolation resistors.
How does the AD826ANZ perform as an ADC buffer in 12-bit systems?
The AD826ANZ achieves 70 ns settling to 0.01% and 2 mV max input offset voltage, enabling full-scale utilization of 12-bit ADCs like the AD872 without gain/offset calibration. Its matched dual channels allow single-ended-to-differential conversion with <0.2 dB gain flatness match at 40 MHz, preserving ENOB and minimizing harmonic distortion in sampled data systems using AD826ANZ.
What is the maximum output current per amplifier in the AD826ANZ?
The AD826ANZ guarantees a minimum output current of 50 mA per amplifier under ±5 V or ±15 V supplies, and 30 mA under +5 V single supply. This allows direct driving of 75 Ω video lines, 150 Ω back-terminated cables, or parallel configurations delivering up to 100 mA - verified across –40°C to +85°C with no derating required for AD826ANZ.
Is the AD826ANZ RoHS compliant?
Yes, the AD826ANZ is RoHS compliant, as indicated by the "Z" suffix in its ordering code. It meets EU Directive 2011/65/EU requirements for restriction of hazardous substances, including lead-free terminations and compliant molding compounds - confirmed in Analog Devices' official ordering guide and material declarations for AD826ANZ.
