Product details
Overview
OPA207IDBVR from Texas Instruments is a precision rail-to-rail output operational amplifier in 5-pin SOT-23 package, delivering ultra-low offset voltage (±130 µV max), ±1.1 µV/°C drift, 1 MHz gain bandwidth, 3.6 V/µs slew rate, and 375 µA quiescent current per amplifier - enabling high-accuracy signal conditioning in battery-powered and industrial sensor front-ends.
For engineers reviewing the OPA207IDBVR datasheet, OPA207IDBVR pinout, OPA207IDBVR application, or OPA207IDBVR equivalent, key selection criteria include input offset stability over temperature, low-noise performance (0.16 µVPP, 0.1–10 Hz), rail-to-rail output swing (≤40 mV from rail, no load), and compatibility with ±2.25 V to ±18 V dual supplies or 4.5–36 V single supply.
Technical Context
The OPA207IDBVR employs super-beta bipolar input transistors with internal bias current cancellation, achieving ≤2.8 nA max input bias current across –40°C to +125°C - outperforming CMOS/JFET op amps at elevated temperatures. Its rail-to-rail output stage uses series-limited transistors to maintain >130 dB open-loop gain while swinging within 40 mV of either supply rail under no-load conditions.
A dedicated slew-boost circuit enables 3.6 V/µs slew rate at only 375 µA quiescent current, supporting fast settling (≤5.4 µs to 0.01%) without phase reversal or overload recovery issues. EMI rejection ratio (EMIRR IN+) exceeds 100 dB below 100 MHz, mitigating RF rectification-induced offset shifts in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset voltage | ±130 µV max (TA = –40°C to +125°C); ensures <0.1% error in 12-bit DAQ systems with ±10 V full-scale range |
| Offset drift | ±1.1 µV/°C max (TA = –40°C to +125°C); contributes <0.01% gain error over 100°C ambient shift in transmitter designs |
| Gain bandwidth | 1 MHz typical; supports stable unity-gain operation and 10 kHz closed-loop bandwidth with 10× margin for anti-alias filtering |
| Slew rate | 3.6 V/µs typical; enables ≤5.4 µs settling to 0.01% for 10 V step, critical for fast-sampling analog input modules |
| Quiescent current | 375 µA max per amplifier; allows dual-op-amp operation on <1 mA total supply in portable battery-test equipment |
| Output swing | ≤40 mV from rail (no load, TA = 25°C); delivers true rail-to-rail dynamic range for ±15 V supplies in pressure transmitters |
| Input noise | 0.16 µVPP (0.1–10 Hz); preserves microvolt-level resolution in thermocouple amplification without external filtering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDBVR | Lower noise (3.8 nV/√Hz vs 7.5 nV/√Hz), higher supply current (3.6 mA vs 0.375 mA), 45 MHz GBW | Better suited for high-speed, low-noise applications like audio preamps; less optimal for battery-powered DAQ | Select OPA211IDBVR when bandwidth >10 MHz and noise <5 nV/√Hz are mandatory; choose OPA207IDBVR for sub-1 mA power budgets |
| AD8628ARJZ-R7 | Zero-drift architecture (0.005 µV/°C), higher quiescent current (1.1 mA), 2.5 MHz GBW, same SOT-23-5 package | Superior long-term DC stability for metrology-grade instruments; higher power limits use in energy-harvesting nodes | Choose AD8628ARJZ-R7 for applications requiring <0.1 µV/°C drift over 10-year life; retain OPA207IDBVR where cost and power are primary constraints |
Compared with OPA211IDBVR and AD8628ARJZ-R7, the OPA207IDBVR uniquely balances ultra-low drift (±1.1 µV/°C), rail-to-rail output, and sub-400 µA quiescent current - making it the optimal choice for industrial sensor signal chains where power, precision, and robustness must coexist without trade-offs.

FAQ
What is the maximum operating temperature range for the OPA207IDBVR?
The OPA207IDBVR is specified to operate from –40°C to +125°C ambient temperature. Electrical characteristics including offset voltage (±225 µV max), drift (±1.1 µV/°C), and open-loop gain (≥120 dB) are guaranteed across this full industrial temperature range, ensuring reliable performance in harsh environments such as factory-floor transmitters and automotive under-hood modules.
Does the OPA207IDBVR require external compensation for unity-gain stability?
No, the OPA207IDBVR is internally compensated for unity-gain stability. It drives capacitive loads up to 200 pF without oscillation and settles to 0.01% in 5.4 µs for a 10 V step - eliminating the need for external compensation networks in buffer, gain, or filter configurations. This simplifies layout and improves reliability in analog input modules and DAQ systems.
Can the OPA207IDBVR be used with single-supply operation?
Yes, the OPA207IDBVR supports single-supply operation from 4.5 V to 36 V. Its rail-to-rail output stage delivers full swing from near-GND to within 40 mV of V+, and its input common-mode range extends to (V–) + 1.25 V, enabling direct interfacing with microcontroller ADC references and sensor bridges without level-shifting circuitry in battery-test and portable instrumentation.
How does the OPA207IDBVR's input bias current compare to CMOS op amps at high temperature?
The OPA207IDBVR uses super-beta bipolar transistors with internal bias current cancellation, limiting input bias current to ≤2.8 nA max at +125°C - whereas typical CMOS op amps exceed 100 nA at the same temperature. This stability eliminates thermal drift-induced errors in high-impedance sensor interfaces like piezoresistive pressure bridges and pH electrodes.
Is the OPA207IDBVR pin-compatible with the OP-07 or OP-177?
No - the OPA207IDBVR is in a 5-pin SOT-23 (DBV) package, while the OP-07 and OP-177 are 8-pin SOIC devices. However, the OPA207 family includes SOIC (OPA207IDR) and VSSOP (OPA207IDGKR) variants that provide direct drop-in replacements for OP-07/OP-177 in existing layouts, retaining identical pinouts and footprint compatibility.
