Product details
Overview
OPA2992IPWR from Texas Instruments is a dual-channel, 40V rail-to-rail input/output precision operational amplifier optimized for high-voltage industrial signal conditioning. It delivers ±210µV offset voltage, 10.6MHz gain-bandwidth, 32V/µs slew rate, and 7nV/√Hz noise at 1kHz - enabling accurate current sensing, ADC driving, and motor control feedback loops in systems operating from 2.7V to 40V.
For engineers reviewing the OPA2992IPWR datasheet, OPA2992IPWR pinout, OPA2992IPWR application, or OPA2992IPWR equivalent, this page provides verified electrical specifications, SOIC-8 package details, dual-channel functional context, and validated alternative options for multiplexed data acquisition, high-side/low-side current sensing, and programmable logic controller analog I/O modules.
Technical Context
The OPA2992IPWR implements a complementary input stage enabling rail-to-rail common-mode input range (V– to V+) and robust MUX-friendly operation - allowing differential inputs up to supply rails without phase reversal. Its high open-loop gain (142dB typical) and 115dB CMRR support precision DC-coupled amplification in noisy industrial environments.
Designed for unity-gain stability with 64° phase margin into 20pF loads, the device features low 2.4mA per amplifier quiescent current and operates across –40°C to +125°C. Its ±65mA short-circuit output current and 7mV rail headroom at no load enable direct interface with heavy capacitive or resistive loads in power stage monitoring circuits.
Key Specifications

| OUT1 | Output, channel 1 | Rail-to-rail swing with 48mV headroom at 10kΩ load - drives ADC reference inputs or comparator thresholds directly |
| V– | Negative (lowest) power supply | Reference node for both channels; must be connected to system ground or negative rail - ties thermal pad in SOIC-D variant |
| IN2+ | Noninverting input, channel 2 | Independent high-impedance node (6TΩ || 1pF) - allows simultaneous dual-sensor conditioning without crosstalk |
| IN2– | Inverting input, channel 2 | Matches IN1– specs - enables matched dual-channel instrumentation amplifier topologies |
| OUT2 | Output, channel 2 | Unity-gain stable with 0.65µs 0.1% settling - suitable for real-time feedback paths in servo drives |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2182IDR | Lower offset (±4µV), higher cost, 5.7MHz GBW, same SOIC-8 package | Better DC accuracy but reduced bandwidth limits use in fast ADC drivers or motor control loops | Select when ultra-low offset dominates over speed; verify layout for lower noise floor requirements |
| AD8638ARZ-REEL7 | Higher offset (±350µV), 1.2MHz GBW, 1.5V/µs slew rate, SOIC-8 | Lower performance envelope suits cost-sensitive, low-bandwidth sensor interfaces only | Choose for non-critical analog front-ends where 10.6MHz bandwidth and 32V/µs slew are unnecessary |
