OPA695ID

Instrumentation, Op Amps, Buffer Amps Overview

The OPA695ID is a single-channel, ultra-wideband current-feedback operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 1.7 GHz and a high slew rate of 4.3 kV/µs. The device operates on a supply voltage range of 5 V to 12 V with a typical quiescent current of 12.9 mA. Key electrical specifications include an input offset voltage of 300 µV, an output current capability of 120 mA, and a common-mode rejection ratio (CMRR) ranging from 51 dB to 56 dB. It is housed in an 8-pin SOIC package and supports an operating temperature range from -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific manufacturer datasheet revision and ordering suffix to ensure compatibility with design requirements. Confirm that the SOIC-8 package dimensions match the target PCB footprint. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the supply voltage limits are respected within the system design constraints.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring high bandwidth and fast transient response without the stability issues often associated with voltage-feedback amplifiers at high frequencies. The integrated disable feature makes it suitable for battery-powered systems where power conservation during idle states is critical. Consider the thermal performance of the SOIC-8 package under continuous high-output current loads.

Instrumentation, Op Amps, Buffer Amps Part Context

The OPA695ID belongs to the OPA695 family of ultra-wideband current-feedback operational amplifiers from Texas Instruments. This series is engineered for applications demanding high dynamic range and low distortion. The ID suffix specifically denotes the industrial temperature grade and the standard 8-pin small-outline integrated circuit (SOIC) package configuration.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes within the same family include the dual-channel OPA2695 and the triple-channel OPA3695. For single-channel alternatives with similar performance characteristics, consider the OPA691 or OPA694. Verify pinout compatibility and package dimensions before substituting.
