OPA140AIDGKR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA140AIDGKR is a single-channel precision operational amplifier manufactured by Texas Instruments, housed in an 8-pin VSSOP package. It features an 11 MHz gain-bandwidth product and a 20 V/µs slew rate. The device operates on supply voltages ranging from 4.5 V to 36 V with a typical quiescent current of 1.8 mA per channel. Key electrical specifications include a maximum input offset voltage of 30 µV, input bias current of 500 fA, and a common-mode rejection ratio of 140 dB. The input voltage noise density is 5.1 nV/√Hz, and it supports rail-to-rail output swing.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'KR' indicates reel packaging when confirming order details against official datasheets. Ensure the A-grade variant matches the required offset voltage specifications for your application. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low noise and high precision in a compact surface-mount package. Compare against standard SOIC versions if thermal dissipation or pin compatibility differs. Consider the rail-to-rail output feature when designing circuits that require full-scale signal swing near the supply rails.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA140 family of JFET-input operational amplifiers designed for high-performance analog signal conditioning. The DGK package variant provides a small form factor suitable for space-constrained designs while maintaining the electrical characteristics of the broader series.
