OPA637AM

Instrumentation, Op Amps, Buffer Amps Overview

The OPA637AM is a precision, high-speed operational amplifier manufactured by Texas Instruments under the Burr-Brown brand. It utilizes Difet® technology to achieve low input bias current and high slew rate. Key electrical parameters include an 80 MHz gain-bandwidth product, a 135 V/µs slew rate, and a maximum supply voltage of 36 V. The device operates with a supply current of 7 mA and features an input offset voltage of 130 µV. It is housed in a TO-99-8 metal can package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify manufacturer origin as Texas Instruments despite the Burr-Brown branding. Confirm the specific suffix 'AM' corresponds to the TO-99-8 metal can package variant. Check component status as end-of-life or obsolete through official channels before procurement planning.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both high speed and precision are required simultaneously. The TO-99-8 package offers superior thermal and mechanical stability compared to plastic packages. Ensure circuit design accommodates the 36 V maximum supply rating and 7 mA quiescent current consumption.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA637 family of precision high-speed operational amplifiers. The 'AM' suffix specifically denotes the metal can package version, distinguishing it from ceramic or plastic variants within the same functional family. It represents the legacy Burr-Brown design now integrated into Texas Instruments' portfolio.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible replacements may be limited due to the specific TO-99-8 package and Difet® architecture. Verify if newer Texas Instruments high-speed op-amps meet the 80 MHz GBW and 135 V/µs slew rate requirements while maintaining similar input bias characteristics.
