Product details
Overview
OPA192ID from Texas Instruments is a single-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. It delivers ±65 mA output current and drives up to 1 nF capacitive loads, making it suitable for high-voltage data-acquisition systems and SAR ADC reference buffering.
For engineers reviewing the OPA192ID datasheet, OPA192ID pinout, OPA192ID application, or OPA192ID equivalent, key selection considerations include its e-trim™-enabled dc precision, differential input voltage range extending to the supply rails, EMI/RFI-filtered inputs, and operation across –40°C to +125°C in industrial environments.
Technical Context
The OPA192ID employs e-trim™ technology for factory-trimmed offset and drift, enabling stable performance without external calibration. Its input stage supports rail-to-rail common-mode range-including beyond the positive rail-and features ultra-low bias current (±5 pA) and high CMRR (140 dB at mid-supply).
Internally, the amplifier integrates robust output protection with thermal shutdown at 140°C and fast overload recovery (200 ns). It maintains 20 V/µs slew rate and 0.00008% THD+N at 1 kHz, supporting high-fidelity signal conditioning in multiplexed sensor front-ends and precision current sensing.
Key Specifications

| Input Offset Voltage | ±5 µV (typ), ±25 µV (max @ 25°C): enables sub-16-bit error budget in 16-bit+ data acquisition |
| Offset Drift | ±0.2 µV/°C (typ): ensures <1 µV total drift over 0–70°C ambient, critical for uncalibrated long-term stability |
| Gain-Bandwidth Product | 10 MHz: allows stable unity-gain configuration with fast settling for 100 kSPS+ SAR ADC drivers |
| Slew Rate | 20 V/µs: supports full-scale step response within 500 ns for 10-V output swings |
| Output Drive | ±65 mA short-circuit current, 1 nF capacitive load drive: eliminates need for external buffer in DAC output stages |
| Common-Mode Rejection | 140 dB (typ, VCM = VS/2): rejects power supply ripple and noise in high-side current sensing |
Pinout & Package
OPA192ID is packaged in an SOIC-8 (D) body measuring 4.90 mm × 3.90 mm, rated for operation from –40°C to +125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | Noninverting input | High-impedance node (10¹³ Ω || 1 pF) accepting rail-to-rail common-mode signals up to (V+) + 0.1 V |
| –IN | Inverting input | Differential input pair node; supports differential input voltage up to full supply rail span |

Applications
| Multiplexed Data-Acquisition System | SAR ADC Reference Buffer |
|---|---|
Use Scenario: 16-bit, 1 MSPS multiplexed DAQ using HV analog switches and precision op amp gain/level-shift stages. IC Role / Device Role / Timing Role: Signal conditioning amplifier after multiplexer; provides gain, antialiasing filter interface, and level translation before ADC. Use Value: Low 5.5 nV/√Hz noise and 140 dB CMRR preserve SNR across channel switching; rail-to-rail input accommodates ±10 V mux outputs. | Use Scenario: Driving REF pin of 16-bit SAR ADC (e.g., ADS8864) with low-noise, low-drift voltage reference buffer. IC Role / Device Role / Timing Role: Precision unity-gain buffer isolating reference source (e.g., REF3140) from dynamic ADC reference current demands. Use Value: ±5 µV offset and ±0.2 µV/°C drift prevent reference voltage error from degrading effective resolution below 16 bits. |
| High-Side Current Sensing | Programmable Logic Controller Analog Input Module |
Use Scenario: Monitoring motor phase current via shunt resistor placed between load and high-voltage bus (e.g., +24 V). IC Role / Device Role / Timing Role: Difference amplifier configured for bidirectional current measurement with common-mode rejection of bus voltage. Use Value: Differential input voltage range to supply rail allows direct sensing at +24 V common-mode; 140 dB CMRR rejects bus ripple. | Use Scenario: Industrial PLC analog input card accepting 0–10 V, ±10 V, and 4–20 mA field signals with cold-junction compensation. IC Role / Device Role / Timing Role: Programmable-gain instrumentation amplifier front-end stage with precision offset trimming and ESD-hardened inputs. Use Value: ±5 pA input bias current prevents voltage error on high-impedance sensor sources; –40°C to +125°C rating ensures reliability in cabinet-mounted controllers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA189ID | Lower 1/f noise (0.1–10 Hz: 0.1 µVPP vs 1.3 µVPP), same 10 MHz GBW, but higher quiescent current (1.3 mA vs 1.0 mA) | Better for ultra-low-frequency sensor amplification (e.g., thermocouples); less optimal for high-speed ADC driving | Select OPA189ID when sub-Hz noise dominates error budget; retain OPA192ID for bandwidth-critical, low-power, or high-CMRR applications. |
| AD8676ARMZ | Higher offset drift (±0.6 µV/°C), lower slew rate (2.5 V/µs), no rail-to-rail input, but superior PSRR (145 dB) | Preferred in low-bandwidth, high-PSRR applications (e.g., precision voltage references); unsuitable for rail-sensing or fast settling | Choose AD8676ARMZ only where supply ripple rejection is paramount and speed/CM range are secondary; OPA192ID remains superior for multiplexed, high-voltage, or fast-settling use cases. |
Compared with OPA189ID and AD8676ARMZ, the OPA192ID uniquely balances ultra-low drift, rail-to-rail input beyond the positive supply, 20 V/µs slew rate, and 1 nF capacitive load drive-making it the optimal choice for high-voltage, high-speed, and high-precision industrial signal chains where multiple performance vectors must be simultaneously satisfied.

FAQ
What is the maximum supply voltage for OPA192ID?
The OPA192ID supports a total supply voltage range of ±2.25 V to ±18 V (or 4.5 V to 36 V single-supply). Absolute maximum ratings specify ±20 V (40 V total), but continuous operation above ±18 V is not recommended. Operation at ±18 V is fully characterized and validated in the datasheet for parameters including offset, bandwidth, and output swing-ensuring reliable performance in 24 V industrial systems.
Does OPA192ID support rail-to-rail input beyond the positive supply rail?
Yes, the OPA192ID features a differential input voltage range that extends to the supply rails-and its common-mode input range includes (V+) + 0.1 V. This allows direct interfacing with high-voltage multiplexer outputs or overvoltage-tolerant sensors without external level-shifting circuitry. The specification is verified across temperature and process corners, and is explicitly documented in Section 6.7 of the SBOS620E datasheet.
Can OPA192ID drive a 1 nF capacitive load stably?
Yes, the OPA192ID is specified to drive ≥1 nF capacitive loads without oscillation or excessive ringing. This capability is confirmed in Typical Characteristics (Figure 32–33) and supported by internal compensation optimized for heavy capacitive loading. It enables direct connection to ADC input capacitors, long PCB traces, or filtering networks-eliminating the need for isolation resistors or external compensation in most designs using the OPA192ID.
What is the thermal shutdown threshold for OPA192ID?
The OPA192ID incorporates thermal protection that activates at a junction temperature of 140°C. Once triggered, the device shuts down output stage operation and automatically recovers when junction temperature falls below the hysteresis threshold (~130°C). This behavior is characterized across package variants (SOIC-8, VSSOP-8, SOT-23-5) and is detailed in the Thermal Protection section of the SBOS620E datasheet.
Is OPA192ID pin-compatible with other devices in the OPAx192 family?
No-OPA192ID (single-channel, SOIC-8) is not pin-compatible with OPA2192 (dual) or OPA4192 (quad), which use different pinouts and package footprints. Within the single-channel variants, OPA192ID (SOIC-8) shares pinout with OPA192IDR (same part number, tape-and-reel), but differs from OPA192DBVR (SOT-23-5) and OPA192DGKR (VSSOP-8), which have distinct pin assignments. Always verify pin mapping against the specific package drawing in the datasheet before layout.
