OPA388IDR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA388IDR is a single-channel, precision CMOS operational amplifier from Texas Instruments' Zero-Drift series. It features a 10 MHz gain-bandwidth product and a 5 V/µs slew rate. Key electrical parameters include a maximum input offset voltage of 250 nV, input bias current of 30 pA, and input noise current density of 100 fA/√Hz. The device operates on a supply voltage range of 2.5 V to 5.5 V with a quiescent current of 1.9 mA per channel. It offers rail-to-rail input and output capabilities, a common-mode rejection ratio of 138 dB, and an output drive capability of 60 mA. The component is housed in an SOIC-8 surface-mount package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IDR' corresponds to the SOIC-8 tape-and-reel packaging configuration. Confirm that the ordering part number matches the required pinout and thermal characteristics for the target PCB layout. Ensure compliance with RoHS directives as indicated by manufacturer specifications. Validate moisture sensitivity levels prior to assembly processing.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when application requirements demand ultra-low offset voltage stability combined with moderate bandwidth. The SOIC-8 package is suitable for standard surface-mount assembly processes. Consider the 60 mA output drive capability for driving capacitive loads or low-impedance circuits without external buffering.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the OPA388 family of zero-drift amplifiers, which includes dual (OPA2388) and quad (OPA4388) variants. The family shares identical core electrical characteristics and architectural design principles. The 'I' designation indicates industrial temperature range operation, while 'D' specifies the SOIC-8 package type.
