FFF CompatibilityThe OPA699ID is housed in the identical SOIC-8 package and matches the OPA689U pinout configuration point-for-point.Both devices share the standard SOIC-8 package outline, dimensions, and SMD mounting style.The OPA699 is stable for gains >= +4, matching the stability profile of the OPA689, but offers faster limiting recovery and better limiting accuracy.The AD8037ARZ shares the exact same pinout for inputs, supplies, output, and clamp/limit voltages (VH and VL) in an 8-SOIC package.Both parts use standard 8-pin SOIC surface mount packages with identical physical dimensions.Functions identically as a high-speed clamping/limiting amplifier with comparable frequency, voltage, and slew rate performance.
AI Summary

OPA689U by Texas Instruments: High Speed Operational Amplifiers Wideband, High Gain Voltage Limiting Amplifier 8-SOIC.

The OPA699ID is the official next-generation upgrade from Texas Instruments for the OPA689U, offering identical gain-stability characteristics, a drop-in physical footprint, and superior clamp timing and accuracy.

  • Direct next-generation upgrade from the same manufacturer designed specifically to replace the OPA689
  • Same exact SOIC-8 package and matching pinout configurations for seamless drop-in replacement
  • Faster overdrive recovery time from limiting (1 ns vs 15 ns)

The AD8037ARZ is an excellent second-source alternative from Analog Devices that serves as a pin-to-pin compatible drop-in replacement, offering extremely low distortion and very similar electrical characteristics.

  • Drop-in pin-compatible alternative from a reputable second source (Analog Devices)
  • Stable for gains >= 2, which fully covers the G >= 4 requirement of the OPA689
  • Comparable high slew rate of 1500 V/µs and -3dB bandwidth of 270 MHz
  • Slightly lower output current capability (70 mA vs 105 mA)
  • Slightly higher supply current consumption (18.5 mA vs 15.5 mA)

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
