TLV2781IDR

Instrumentation, Op Amps, Buffer Amps Overview

The TLV2781IDR is a single-channel operational amplifier from Texas Instruments, designed for low-voltage applications. It operates within a supply voltage range of 1.8 V to 3.6 V and supports dual supplies from ±0.9 V to ±1.8 V. The device features rail-to-rail input and output capabilities, ensuring maximum dynamic range. Key electrical specifications include an 8 MHz gain-bandwidth product, a slew rate of 5 V/µs, and a quiescent current of 650 µA. It offers a typical input offset voltage of 3 mV and an input bias current of 15 pA. The component is housed in an 8-SOIC package and functions reliably across an industrial temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IDR' confirms the 8-SOIC surface-mount package and industrial temperature grade (-40°C to +125°C). Confirm RoHS compliance status through the manufacturer's official documentation. Ensure the ordering part number matches the required pinout and thermal characteristics for the target PCB layout.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel op-amp with rail-to-rail I/O is required under a 3.6 V maximum supply. The 8 MHz bandwidth suits moderate-speed signal processing tasks. Consider the 8-SOIC package constraints for board space. Compare against other TLV278x variants if multiple channels or different packaging options are needed.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the TLV278x family of low-power, high-speed operational amplifiers. The family includes single (TLV2781), dual (TLV2782), and quad (TLV2785) channel configurations. All variants share similar electrical characteristics, including the 650 µA quiescent current and rail-to-rail performance, differing primarily in channel count and physical package type.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Compatible substitutes within the same family include TLV2781CDR (commercial grade) and TLV2781IDRT (tape and reel packaging). Verify that alternative packages maintain the same pinout compatibility for direct replacement without schematic changes.
