Product details
Overview
OPA207IDR from Texas Instruments is a precision rail-to-rail output operational amplifier designed for high-accuracy signal conditioning in low-power industrial sensing and data acquisition systems. It delivers ultra-low 150 μV max input offset voltage, ±1 μV/°C max drift, 1 MHz gain bandwidth, 3.6 V/μs slew rate, and operates from ±2.25 V to ±18 V supplies - enabling high-resolution analog front-ends in battery-powered and wide-supply industrial transmitters.
For engineers reviewing the OPA207IDR datasheet, OPA207IDR pinout, OPA207IDR application, or OPA207IDR equivalent, this page provides verified specifications, SOIC-8 package details, real-world use cases in pressure/temperature transmitters and DAQ modules, and two validated alternative op amps with documented functional trade-offs.
Technical Context
The OPA207IDR employs super-beta bipolar input transistors with internal bias current cancellation, achieving ≤2.8 nA max input bias current over –40°C to +125°C - outperforming CMOS/JFET amplifiers at elevated temperatures. Its rail-to-rail output stage swings within 15 mV of either rail under no load, maintaining ≥130 dB open-loop gain and ≥115 dB CMRR across full temperature range.
It integrates slew-boost circuitry to deliver 3.6 V/μs slew rate at only 375 μA max quiescent current per amplifier, and features EMI rejection ratio (EMIRR IN+) >100 dB at 900 MHz - critical for noisy industrial environments. The device is unity-gain stable and immune to phase reversal during common-mode overdrive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | 150 μV (max) - enables <1 LSB error in 16-bit ADC systems with ±10 V input range |
| Offset voltage drift | ±1 μV/°C (max) - ensures <10 μV total drift over 85°C ambient range, critical for uncalibrated sensor interfaces |
| Gain bandwidth | 1 MHz (typ) - supports stable closed-loop operation up to 100 kHz with G = 10, suitable for anti-alias filtering |
| Slew rate | 3.6 V/μs (typ) - allows full-scale 10 V step settling in <3 μs, meeting fast DAQ timing requirements |
| Supply range | ±2.25 V to ±18 V - accommodates legacy ±15 V rails and modern low-voltage ±2.5 V or ±3.3 V systems |
| Quiescent current | 375 μA (max) - permits dual-opamp operation below 1 mA total, extending battery life in portable test equipment |
| CMRR | 115 dB (min) - rejects >560,000:1 common-mode interference, essential for bridge sensor amplification |
Pinout & Package
OPA207IDR is packaged in an 8-pin SOIC (D) package measuring 4.90 mm × 3.91 mm, with standard JEDEC MS-012AC footprint and 1.27 mm pitch. Pin 1 is marked with a dot; pins are numbered counterclockwise from top-left corner when viewed from top with marking band at top-left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No connect (NC) | Internally unconnected - may be left floating or tied to ground for mechanical stability; no electrical function |
| 2 | Inverting input (–IN) | Differential input node; accepts feedback network for inverting configurations; high-impedance (1 GΩ || 1 pF) |
| 3 | Non-inverting input (+IN) | Differential input node; used for non-inverting gain stages and reference buffering; EMI-optimized layout recommended |
| 4 | Negative supply (V–) | Lowest potential rail connection; requires local 0.1 μF ceramic decoupling to minimize PSRR degradation |
| 5 | No connect (NC) | Internally unconnected - no routing or grounding required; avoid PCB trace stubs |
| 6 | Output (OUT) | Rail-to-rail output capable of sourcing/sinking ±40 mA; drives ≥200 pF capacitive loads without instability |
| 7 | Positive supply (V+) | Highest potential rail connection; paired decoupling with V– ensures balanced PSRR performance |
| 8 | No connect (NC) | Internally unconnected - electrically isolated; no thermal or mechanical dependency |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low offset drift | ±1 μV/°C max ensures <15 μV total shift over full –40°C to +125°C operating range, eliminating need for system recalibration |
| Rail-to-rail output swing | 15 mV from rail (no load) enables full dynamic range utilization in single-supply 3.3 V or dual-supply ±5 V systems |
| EMI rejection ratio | >100 dB at 900 MHz (EMIRR IN+) suppresses RF rectification-induced offset shifts in wireless-adjacent industrial enclosures |
| Input bias current cancellation | ≤2.8 nA max over temperature avoids external compensation resistors and preserves THD+N < –114 dB at 1 kHz |
| Unity-gain stability | No external compensation required - simplifies layout for G = 1 buffer, follower, or active filter designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | Lower 1.1 μVpp 0.1–10 Hz noise, higher 45 mA output drive, but 3.6 mA IQ - 10× higher power than OPA207IDR | Better for ultra-low-noise sensor front-ends where power is secondary; unsuitable for battery-operated DAQ | Select OPA211IDR only when sub-μVpp noise dominates design priority over quiescent current |
| OPA188IDR | Zero-drift architecture (0.005 μV/°C), lower 135 nV/√Hz noise, but 1.3 mA IQ and limited 0.65 MHz GBW | Ideal for DC-critical applications like strain gauge bridges requiring zero long-term drift; slower settling limits high-speed DAQ | Choose OPA188IDR for <1 ppm/°C drift-critical calibration equipment; avoid when >100 kHz signal bandwidth needed |
Compared with OPA207IDR, OPA211IDR trades 10× higher supply current for 3× lower noise, while OPA188IDR eliminates drift at the cost of bandwidth and power - making OPA207IDR the optimal balance of precision, speed, and efficiency for general-purpose industrial signal chains.

FAQ
What is the maximum operating temperature range for the OPA207IDR?
The OPA207IDR is specified for continuous operation from –40°C to +125°C ambient temperature, with all key parameters - including offset voltage, drift, CMRR, and open-loop gain - guaranteed across this full industrial range per the SBOS826D datasheet revision.
Does the OPA207IDR require external compensation for unity-gain stability?
No, the OPA207IDR is internally compensated for unity-gain stability. It drives capacitive loads up to 200 pF without oscillation and maintains phase margin >60° in G = 1 configurations - eliminating need for external compensation networks or isolation resistors.
Can the OPA207IDR replace OP-07 or OP-177 in existing designs?
Yes, the OPA207IDR is explicitly positioned as a drop-in replacement for OP-07, OP-77, and OP-177. It matches SOIC-8 pinout, offers superior noise (0.16 μVPP vs 0.25 μVPP), wider output swing, twice the bandwidth, and half the quiescent current - enabling direct substitution with performance uplift.
What is the typical input voltage noise density of the OPA207IDR at 1 kHz?
The OPA207IDR has a typical input voltage noise density of 7.5 nV/√Hz at 1 kHz, consistent across frequency from 10 Hz to 100 kHz - supporting high-fidelity signal conditioning in audio-grade and precision measurement applications without added filtering.
Is the OPA207IDR susceptible to phase reversal during input overvoltage conditions?
No, the OPA207IDR is specifically designed to be free from phase reversal. Its input stage includes protection circuitry that prevents output polarity inversion even when inputs exceed common-mode range by ±10 V - ensuring safe operation in overload-prone industrial sensor interfaces.
