OPA170AIDR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA170AIDR is a single-channel precision operational amplifier manufactured by Texas Instruments. It features rail-to-rail input and output capabilities, supporting supply voltages from 2.7 V to 36 V. Key electrical specifications include a gain-bandwidth product of 1.2 MHz, a slew rate of 400 mV/us, and an input offset voltage of 250 uV. The device operates with a quiescent current of 110 uA and provides an output current of 17 mA per channel. It exhibits low input bias current (8 pA) and high common-mode rejection ratio (120 dB). The component is housed in an 8-SOIC 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 'DR' corresponds to the tape-and-reel packaging format when ordering. Confirm that the A-grade specification meets the required offset voltage and drift tolerances for the application. Ensure the SOIC-8 footprint matches the PCB design guidelines provided in the official datasheet. Check for RoHS compliance status if environmental regulations apply to the manufacturing region.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel amplifier with rail-to-rail I/O is required alongside micro-power efficiency. Compare against dual or quad variants like OPA2170 or OPA4170 if multiple channels are needed, noting they share identical electrical characteristics. Consider the 8-SOIC package constraints versus smaller alternatives like SOT-5X3 if board space is limited. Validate that the 1.2 MHz bandwidth suffices for the target signal frequencies.

Instrumentation, Op Amps, Buffer Amps Part Context

The OPA170AIDR belongs to the OPAx170 family of low-power operational amplifiers from Texas Instruments. This family includes single, dual, and quad versions designed for flexibility in multi-channel designs. The devices are characterized for operation over an extended industrial temperature range and support wide single-supply voltages. They are engineered to prevent phase reversal when input signals exceed the supply rails.
