OPA177GPG4

Instrumentation, Op Amps, Buffer Amps Overview

The OPA177GPG4 is a single-channel, precision operational amplifier manufactured by Texas Instruments. It features a JFET input stage with low offset voltage and drift. The device operates on dual supplies ranging from ±2V to ±18V or a single supply of 4V to 36V. Key electrical specifications include a gain-bandwidth product of 600 kHz, a slew rate of 0.3 V/µs, and an input bias current of 500 pA. It is housed in an 8-pin PDIP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the component status as obsolete or end-of-life through official Texas Instruments channels before finalizing design-in decisions. Confirm that the specific GPG4 suffix corresponds to the 8-PDIP package variant required for your application. Ensure compatibility with existing PCB footprints if replacing active components. Check for valid RoHS compliance documentation associated with this specific manufacturing lot.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low-frequency precision is prioritized over high-speed performance. The 600 kHz bandwidth and 0.3 V/µs slew rate limit suitability for high-frequency applications. Consider the 8-PDIP package constraints for automated assembly versus surface-mount alternatives like the GS variant. Evaluate thermal dissipation requirements within the through-hole package format.
