OPA379AIDCKT

Instrumentation, Op Amps, Buffer Amps Overview

The OPA379AIDCKT is a single-channel operational amplifier from the Texas Instruments OPA379 family, housed in an SC-70-5 surface-mount package. It operates on a supply voltage range of 1.8 V to 5.5 V with a typical quiescent current of 2.9 µA per channel. Key electrical specifications include a gain-bandwidth product of 90 kHz, a slew rate of 30 mV/µs, and an input offset voltage of 1.5 mV. The device features rail-to-rail input and output capabilities, a common-mode rejection ratio of 100 dB, and an input voltage noise density of 80 nV/√Hz. It supports an operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix CKT indicates cut-tape packaging when ordering. Confirm the A-grade designation matches required offset voltage tolerances. Ensure the SC-70-5 footprint aligns with PCB layout constraints. Check moisture sensitivity levels for reflow soldering profiles. Validate that the 1.5 mV max Vos meets system accuracy requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low static current is critical alongside moderate precision needs. The OPA379 offers lower bandwidth than the OPA378 but significantly reduced power usage. Consider the SC-70-5 package size for space-constrained designs. Compare against the OPA369 if zero-crossover distortion is not a primary concern.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA37x series of ultra-low-power, rail-to-rail input/output operational amplifiers. It complements higher-speed variants like the OPA377 and OPA378 by prioritizing energy efficiency over bandwidth. The device is designed for applications where power conservation is more important than high-frequency response.
