Replacement verdict
Compatible functional replacement candidate
The AD826AR and AD826AR-REEL7 are the same dual high-speed operational amplifier die in the same 8-lead SOIC package, differing only in packaging format (tube vs. tape-and-reel). They are functionally identical and fully interchangeable; the REEL7 suffix denotes a 750-unit tape-and-reel shipment option rather than any electrical or mechanical variation.

Key electrical and mechanical differences between the two devices
| Parameter | AD826AR | AD826AR-REEL7 | Why it matters |
|---|---|---|---|
| Amplifier Type | Voltage Feedback, High Speed | Voltage Feedback, High Speed | Confirms both parts are the same amplifier core, so functional behavior is identical. |
| Number of Channels | 2 | 2 | Dual-channel configuration must match for drop-in substitution in a circuit. |
| Gain Bandwidth Product | 50 MHz | 50 MHz | Determines the maximum usable frequency and closed-loop bandwidth of the amplifier. |
| Slew Rate | 350 V/µs | 350 V/µs | Affects large-signal transient response and distortion at high frequencies. |
| Input Offset Voltage (max) | 0.5 mV | 0.5 mV | DC accuracy depends on offset voltage; matching values ensure equivalent precision. |
| Supply Voltage Range | ±5 V to ±15 V | ±5 V to ±15 V | Must be compatible with the existing power rails for direct replacement. |
| Package / Mounting | 8-Lead SOIC (Surface Mount) | 8-Lead SOIC (Surface Mount) | Same package and footprint allow physical interchangeability on the PCB. |
| Packaging / Delivery Form | Tube / Individual | Tape & Reel (7-inch reel) | Delivery format differs; reel packaging suits automated assembly while tube suits prototyping. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Ensures both parts meet the same environmental operating requirements. |

Frequently asked questions
What is the difference between AD826AR and AD826AR-REEL7?
Both parts are the same AD826 dual high-speed operational amplifier die in the same 8-lead SOIC (R-8) package. The only difference is packaging format: AD826AR is supplied in standard tube/rail packaging, while AD826AR-REEL7 is supplied on a 7-inch tape-and-reel carrier for automated pick-and-place assembly. Electrical and thermal specifications are identical.
Are AD826AR and AD826AR-REEL7 electrically and functionally interchangeable?
Yes. Since both ordering codes refer to the same AD826AR device in the same 8-lead SOIC package, they share identical specifications, including 50 MHz unity-gain bandwidth, 350 V/µs slew rate, 50 mA output current, and ±5 V to ±15 V dual-supply operation. They differ only in shipping packaging.
Which package do AD826AR and AD826AR-REEL7 use?
Both are offered in the 8-lead SOIC package (Analog Devices R-8 suffix), with a 1.27 mm lead pitch and a body width of approximately 3.9 mm. The PCB land pattern is the same for both ordering codes.
What are the key AC specifications of the AD826?
The AD826 is a dual voltage-feedback op amp with 50 MHz unity-gain bandwidth, 350 V/µs slew rate, and 0.07% differential gain / 0.03° differential phase error, making it suitable for video and high-speed signal processing. These parameters apply equally to AD826AR and AD826AR-REEL7.
What supply voltage range does the AD826 support?
The AD826 operates from dual supplies of ±5 V to ±15 V. Both AD826AR and AD826AR-REEL7 are specified over this range, and the absolute maximum supply is ±18 V.
What is the operating temperature range for AD826AR and AD826AR-REEL7?
Both ordering codes are specified for the industrial temperature range of −40°C to +85°C. The AD826AR grade is not specified for the extended −40°C to +125°C range.
Can AD826AR-REEL7 be used as a drop-in replacement for AD826AR in an existing design?
Yes, from an electrical and footprint standpoint they are the same device. The only consideration is assembly: AD826AR-REEL7 is intended for reel-fed automated placement, while AD826AR in tubes is typically used for manual or low-volume assembly. Verify your pick-and-place equipment accepts 7-inch reels before switching.
What is the moisture sensitivity level (MSL) of these parts?
Both AD826AR and AD826AR-REEL7 are classified MSL 1 (no dry-pack required) per the Analog Devices datasheet, meaning unlimited floor life at ≤30°C/85% RH. Confirm the MSL marking on the delivered reel or tube label against your process requirements.
