Product details
Overview
OPA992SIDBVR from Texas Instruments is a single-channel, 40V rail-to-rail input/output precision operational amplifier optimized for high-voltage industrial signal conditioning. It delivers ±210 µV offset voltage, 10.6 MHz gain-bandwidth, 32 V/µs slew rate, and 7 nV/√Hz input voltage noise at 1 kHz - enabling accurate current sensing, ADC driving, and high-side comparator operation in motor control and power delivery systems.
For engineers reviewing the OPA992SIDBVR datasheet, OPA992SIDBVR pinout, OPA992SIDBVR application, or OPA992SIDBVR equivalent, key selection criteria include its ±20 V (±1.35 V to ±20 V) dual-supply range, MUX-friendly differential input capability up to supply rails, robust 115 dB CMRR, low 2.4 mA quiescent current per amplifier, and operation across –40°C to +125°C.
Technical Context
The OPA992SIDBVR implements a high-voltage complementary bipolar input stage with rail-to-rail output swing, supporting true open-loop comparator use and multiplexer-tolerant inputs. Its architecture enables stable unity-gain operation while maintaining 64° phase margin into 20 pF capacitive loads.
It features integrated EMI rejection circuitry (EMIRR), low 10 pA bias current, and differential input voltage tolerance up to the full supply rail - allowing direct connection to high-impedance sources without external clamping diodes in data-acquisition front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 40 V single-supply or ±1.35 V to ±20 V dual-supply - supports wide industrial bus voltages including 24 V and 36 V systems. |
| Input Offset Voltage | ±0.21 mV typical - enables sub-0.1% error in 12-bit+ current-sense applications with 100 mΩ shunts. |
| Gain-Bandwidth Product | 10.6 MHz - sufficient for closed-loop settling of 16-bit ADC drivers within 0.65 µs (0.1%) at G = +1. |
| Slew Rate | 32 V/µs - ensures distortion-free amplification of fast transients in motor phase current feedback loops. |
| Input Voltage Noise | 7 nV/√Hz @ 1 kHz - critical for preserving SNR in low-level sensor interfaces like strain gauges and thermopiles. |
| Common-Mode Rejection | 115 dB - rejects supply ripple and ground bounce in high-side current sensing with 100:1 common-mode rejection ratio. |
| Quiescent Current | 2.48 mA per amplifier - balances performance and power efficiency in always-on industrial I/O modules. |
Pinout & Package
OPA992SIDBVR is packaged in a 5-pin SOT-23 (DBV) package measuring 2.9 mm × 2.8 mm, rated for operation from –40°C to +125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Output | Rail-to-rail output capable of sourcing/sinking ±65 mA; drives 10 kΩ loads to within 48 mV of rails at 40 V supply. |
| 2 (V–) | Negative Supply | Lowest potential node; must be connected to system ground or negative rail; thermal pad (if present) connects here in WSON variants (not applicable to DBV). |
| 3 (IN+) | Noninverting Input | High-impedance (6 TΩ || 1 pF) node; accepts common-mode signals from V– to V+ - enables direct connection to shunt resistors in high-side sensing. |
| 4 (IN–) | Inverting Input | Differential input tolerant up to supply rails; usable in open-loop comparator mode with hysteresis via external feedback. |
| 5 (V+) | Positive Supply | Highest potential node; supports up to 40 V absolute maximum rating; decoupling capacitor required near pin for stability. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2182DR | Lower offset (±4 µV), lower noise (5.7 nV/√Hz), but limited to 36 V max supply and higher IQ (700 µA). | Better for ultra-low-drift lab equipment; unsuitable for 40 V industrial bus monitoring. | Select OPA2182DR only when supply ≤36 V and sub-µV offset is mandatory - not a drop-in replacement for OPA992SIDBVR. |
| AD8676ARZ | Higher offset (±75 µV), lower bandwidth (10 MHz), same 36 V max supply, but superior PSRR (140 dB). | Preferred in mixed-signal systems with heavy digital noise coupling; lacks rail-to-rail input. | Choose AD8676ARZ when PSRR dominates over CMRR and supply stays ≤36 V - requires layout changes due to non-rail-to-rail input. |
Compared with OPA2182DR and AD8676ARZ, OPA992SIDBVR uniquely combines 40 V operation, rail-to-rail input, and <1 µV/°C total drift - making it the only option for high-side current sensing in 40 V motor drives without external level shifters or supply derating.

FAQ
What is the maximum supply voltage for OPA992SIDBVR?
The OPA992SIDBVR supports an absolute maximum supply voltage of 42 V (V+ to V–), with recommended operation up to 40 V. This allows direct integration into 36 V and 40 V industrial bus systems without external regulators or voltage dividers - a key advantage over 36 V-limited alternatives like OPA2182DR or AD8676ARZ.
Does OPA992SIDBVR support rail-to-rail input and output simultaneously?
Yes, OPA992SIDBVR supports rail-to-rail input (common-mode range from V– to V+) and rail-to-rail output (swing within 7 mV of rails at no load, 48 mV at 10 kΩ) across its full 2.7–40 V supply range. This enables single-supply operation in sensor interfaces where both input signal and output headroom must maximize dynamic range - such as shunt-based current measurement in 24 V systems.
Can OPA992SIDBVR be used as a comparator?
Yes, OPA992SIDBVR is explicitly designed for open-loop comparator use due to its MUX-friendly inputs, rail-to-rail input range, and fast overload recovery (170 ns). Unlike standard op amps, it avoids phase reversal and remains stable when inputs exceed supply rails - making it suitable for overvoltage/undervoltage detection in power supplies without external clamping diodes.
What is the thermal resistance (RθJA) of the OPA992SIDBVR DBV package?
The OPA992SIDBVR in the 5-pin SOT-23 (DBV) package has a junction-to-ambient thermal resistance (RθJA) of 185.4°C/W under standard JEDEC test conditions. This value assumes no PCB copper pour; adding 1-inch² thermal pad on the board reduces effective RθJA by ~30%, enabling continuous operation at full 2.48 mA quiescent current even at +125°C ambient.
Is OPA992SIDBVR qualified for automotive applications?
No, OPA992SIDBVR is specified for industrial temperature range (–40°C to +125°C) and is not AEC-Q100 qualified. While its operating range overlaps with automotive Grade 3, it lacks automotive-specific qualification testing (e.g., HTOL, ESD, EMC). For automotive use, TI recommends the pin-compatible OPA992QDBVR (Q1 grade), which shares identical electrical specs but includes full AEC-Q100 certification and enhanced process controls.
