What the 350 V/µs slew rate buys you on the bench
The AD826ARZ-REEL7 is a dual voltage-feedback op-amp with a 350 V/µs slew rate — that is the large-signal response, not the small-signal bandwidth. For a 10 V output step, the rise time is about 28 ns, which means the amplifier can reproduce a 10 Vpp sine wave up to roughly 5.6 MHz before slew limiting sets in. The -3 dB bandwidth and gain-bandwidth product both sit at 50 MHz, so the small-signal gain rolls off at 20 dB/decade above that pole. Unity-gain stable — no external compensation needed for a buffer configuration. Each channel delivers 50 mA of output current, enough to drive a 50 Ω load to ±2.5 V or a coaxial cable directly without a separate buffer stage.
Supply rails and temperature — where this part fits on the board
Supply span runs from 5 V to 36 V, so you can run it on ±2.5 V up to ±18 V dual supplies or a single 5 V to 36 V rail. The 6.6 mA quiescent per channel is the idle draw — the total chip current at no load is 13.2 mA typical. Rated for -40°C to 85°C ambient — the industrial temperature grade means it is specified for factory-floor enclosures, outdoor telecom cabinets, and engine-bay-adjacent equipment that does not see under-hood extremes. Input offset voltage is 500 µV typical, input bias current 3.3 µA. These are moderate values — fine for a video line driver or ADC front-end where the signal is several hundred millivolts, but not a precision instrumentation amp.
Package and sourcing — 8-SOIC on tape, active lifecycle
Housed in an 8-SOIC package (3.90 mm body width), surface-mount. The REEL7 suffix means it ships on 7-inch tape-and-reel — 1000 pieces per reel typical for this Analog Devices family. The cut-tape option is also listed for prototype quantities. Lifecycle status is active — no end-of-life notice from Analog Devices. This is a current-production part, not a last-time-buy or NRND situation. Sourced through authorized and independent distribution; pricing and lead time confirmed against your BOM quantity at RFQ. RoHS3 compliant per the manufacturer's declaration — no exemptions on the restricted substances.
