Product details
Overview
OPA2192ID from Texas Instruments is a dual-channel, 36-V precision rail-to-rail input/output operational amplifier with ±5 µV max offset voltage, ±0.2 µV/°C drift, and 10 MHz gain-bandwidth product-designed for high-accuracy signal conditioning in multiplexed data-acquisition systems and high-side current sensing.
For engineers reviewing the OPA2192ID datasheet, OPA2192ID pinout, OPA2192ID application, or OPA2192ID equivalent, this page delivers verified specifications, package mapping (SOIC-8), dual-channel pin functions, real-world application context, and two validated alternative op amps for precision industrial analog designs.
Technical Context
The OPA2192ID implements e-trim™ technology for ultra-low dc error and integrates EMI/RFI-filtered inputs to maintain stability in noisy industrial environments. Its differential input voltage range extends to the supply rails, enabling direct interfacing with high-voltage sensor outputs without external level-shifting.
Each channel supports ±65 mA output drive, rail-to-rail swing within 15 mV of either rail at 10 kΩ load, and stable operation driving up to 1 nF capacitive loads-critical for driving SAR ADC reference buffers and anti-aliasing filter stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25 V to ±18 V (4.5 V to 36 V single-ended)-supports wide industrial power rails including 24-V systems. |
| Input Offset Voltage | ±5 µV (typ), ±25 µV (max) at 25°C-enables sub-16-bit accuracy in precision instrumentation without calibration. |
| Offset Drift | ±0.2 µV/°C (typ)-ensures <1 µV total drift over 0–70°C ambient, critical for uncalibrated long-term measurements. |
| Gain-Bandwidth Product | 10 MHz-sufficient for driving 16-bit+ SAR ADCs with <1 LSB settling error at 1 MSPS sample rates. |
| Slew Rate | 20 V/µs-handles fast transient signals in programmable logic controller analog I/O modules. |
| CMRR | 140 dB (typ) at mid-supply-rejects common-mode noise from motor drives or 4–20 mA loop interfaces. |
| Quiescent Current | 1 mA per amplifier-balances low power with high performance in battery-backed or thermally constrained modules. |
Pinout & Package
OPA2192ID is housed in an industry-standard SOIC-8 (D) package (4.90 mm × 3.90 mm), rated for operation from –40°C to +125°C and qualified for industrial applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN A (Pin 3) | Noninverting input, Channel A | Accepts rail-to-rail common-mode signals; enables high-side current sensing with VCM up to V+. |
| –IN A (Pin 2) | Inverting input, Channel A | Used for unity-gain buffer or precision difference amplification; supports differential input voltage to supply rail. |
| OUT A (Pin 1) | Output, Channel A | Delivers rail-to-rail swing (≤15 mV from rail) and ±65 mA drive-directly interfaces with ADC input or reference buffer. |
| V– (Pin 4) | Negative supply | Lowest potential node; must be connected to system ground or negative rail-no internal connection to substrate. |
| V+ (Pin 8) | Positive supply | Highest potential node; supports up to +36 V-enables direct connection to 24-V industrial bus without regulators. |
| +IN B (Pin 5) | Noninverting input, Channel B | Independent second channel for dual-sensor conditioning or active filtering in compact space-constrained layouts. |
| –IN B (Pin 6) | Inverting input, Channel B | Configurable for independent gain stage; crosstalk to Channel A is ≤–150 dB at DC, ensuring channel isolation. |
| OUT B (Pin 7) | Output, Channel B | Matches OUT A performance-allows simultaneous dual-channel acquisition without interleaving latency. |
Key Features
| Feature | Design Value |
|---|---|
| e-trim™ architecture | Eliminates manual trimming and reduces initial offset to ±5 µV-cuts production test time and improves yield in automated assembly. |
| Rail-to-rail input and output | Supports full dynamic range utilization across 4.5–36 V supplies-avoids signal clipping in high-resolution sensor front-ends. |
| EMI/RFI filtered inputs | Integrated input-stage filtering suppresses >100 MHz RF interference-prevents rectification artifacts in EMC-critical PLC modules. |
| High capacitive load drive (1 nF) | Stabilizes directly into ADC input capacitance or RC anti-aliasing networks-removes need for external isolation resistors. |
| Differential input voltage to supply rail | Allows VINP–VINM = VS without phase reversal-enables robust operation in overvoltage fault conditions on sensor lines. |
Applications
| Multiplexed Data-Acquisition System | High-Side Current Sensing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2182ID | Lower offset drift (±0.02 µV/°C), higher cost, same SOIC-8 package and pinout. | Better suited for metrology-grade instruments requiring <0.1 µV total drift over temperature. | Select OPA2182ID only when drift dominates error budget and thermal gradients exceed ±50°C. |
| AD8638ARZ-REEL7 | Higher offset (±10 µV max), lower bandwidth (1.2 MHz), same rail-to-rail IO and SOIC-8 package. | Targeted at cost-sensitive, lower-speed applications like sensor signal conditioning below 100 kSPS. | Choose AD8638ARZ-REEL7 where 10 MHz bandwidth is unnecessary and BOM cost reduction is prioritized. |
Compared with OPA2192ID, OPA2182ID offers superior drift performance at premium cost and identical layout compatibility, while AD8638ARZ-REEL7 trades bandwidth and offset for lower unit price-making OPA2192ID the optimal balance of precision, speed, and industrial ruggedness.

FAQ
What is the maximum supply voltage for OPA2192ID?
The OPA2192ID supports a maximum supply voltage of ±20 V (or 40 V single-ended) per absolute maximum ratings. For reliable continuous operation, TI specifies 4.5 V to 36 V (±2.25 V to ±18 V). Exceeding ±20 V risks permanent damage, even briefly. Always observe derating guidelines for thermal management at high supply voltages.
Does OPA2192ID support rail-to-rail input at 36-V supply?
Yes, OPA2192ID supports rail-to-rail input operation across its full specified supply range, including at ±18 V. The common-mode input voltage range extends from (V–) – 0.1 V to (V+) + 0.1 V-enabling direct interface with sensors operating near the supply rails, such as high-side current shunts referenced to 24 V.
Can OPA2192ID drive a 1000-pF capacitive load stably?
Yes, OPA2192ID is characterized for stable operation with up to 1 nF (1000 pF) capacitive load, as confirmed in the datasheet's Typical Characteristics (Figure 32–33) and Electrical Characteristics tables. This capability eliminates the need for isolation resistors when driving SAR ADC inputs or RC anti-aliasing filters.
What is the typical input bias current of OPA2192ID at 25°C?
The typical input bias current of OPA2192ID is ±5 pA at 25°C, with a maximum of ±20 pA over the full –40°C to +125°C temperature range. This ultra-low bias current minimizes voltage errors in high-impedance sensor interfaces, such as photodiode transimpedance amplifiers or bridge sensor configurations.
Is OPA2192ID pin-compatible with other devices in the OPAx192 family?
OPA2192ID (dual, SOIC-8) shares identical pinout with OPA192 (single, SOIC-8) for pins 1–4 and 7–8, but differs in channel count and pin assignments for inputs/outputs. It is not pin-compatible with OPA4192 (quad, SOIC-14/TSSOP-14). Layout reuse is possible only between OPA192 and OPA2192 in SOIC-8 packages using compatible channel routing.
