OPA317IDR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA317IDR is a single-channel, low-offset, rail-to-rail input and output operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 300 kHz and a slew rate of 150 mV/us. The device operates with an input offset voltage of 90 uV and an input bias current of 275 pA. It supports a supply voltage range from 1.8 V to 5.5 V, drawing a typical operating power supply current of 21 uA. Each channel can source or sink up to 5 mA of output current. The component offers a common-mode rejection ratio of 108 dB and an input voltage noise density of 55 nV/sqrt Hz. It is housed in an SC-70-5 surface-mount package and functions within a temperature range of -40 C to +125 C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IDR' corresponds to the SC-70-5 tape-and-reel packaging configuration. Confirm that the single-channel variant matches the design requirements, as other family members may offer dual or quad configurations. Ensure the operating environment stays within the specified -40 C to +125 C thermal limits. Cross-reference the datasheet revision date to ensure compatibility with current design standards.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel amplifier with rail-to-rail I/O is required alongside minimal power consumption. The 300 kHz bandwidth suits low-frequency signal conditioning tasks. Compare against dual or quad variants if multiple channels are needed to reduce board space. Verify that the 5 mA output drive capability meets load requirements without external buffering.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPAx317 family of zero-drift, low-offset operational amplifiers. The family includes single (OPA317), dual (OPA2317), and quad (OPA4317) channel versions. These devices share similar electrical characteristics but differ in channel count and package options. The OPA317 specifically provides a compact solution for space-constrained designs requiring precision amplification.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible substitutes within the same family include the OPA317IDCKT (SC-70-5 reel). Other channel counts like OPA2317 or OPA4317 require schematic redesign. Non-TI equivalents must be evaluated for matching rail-to-rail performance and low offset specifications.
