Product details
Overview
OPA207ID from Texas Instruments is a precision rail-to-rail output operational amplifier designed for low-noise, high-accuracy signal conditioning in industrial sensing and data acquisition systems. It delivers 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-fidelity analog front-ends in battery-powered and wide-supply industrial transmitters.
For engineers reviewing the OPA207ID datasheet, OPA207ID pinout, OPA207ID application, or OPA207ID equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options for precision op amp selection in analog input modules, pressure/temperature transmitters, and battery test equipment.
Technical Context
The OPA207ID uses super-beta bipolar input transistors with internal bias current cancellation, achieving ≤2.8 nA max input bias current across –40°C to +125°C - unlike CMOS/JFET amplifiers whose bias current doubles per 10°C rise. Its rail-to-rail output stage swings within 15 mV of either rail under no load, maintaining ≥130 dB open-loop gain at full swing.
A novel slew-boost architecture enables 3.6 V/μs slew rate while consuming only 375 μA max quiescent current per amplifier. The device is unity-gain stable, immune to phase reversal, and features EMI rejection ratio (EMIRR IN+) >100 dB at 900 MHz - critical for noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 150 μV (max) - ensures ≤0.001% error in 15 V full-scale measurement systems without trimming |
| Offset Drift | ±1 μV/°C (max) - guarantees <15 μV total drift over 15°C ambient change in transmitter calibration |
| Gain Bandwidth | 1 MHz (typical) - supports stable closed-loop operation up to 100 kHz with G = 10 configuration |
| Slew Rate | 3.6 V/μs (typical) - enables ≤5.4 μs settling to 0.01% for 10 V step, critical for fast DAQ sampling |
| Supply Range | ±2.25 V to ±18 V - accommodates dual-supply industrial sensors and single-supply 4–20 mA loop interfaces |
| Quiescent Current | 375 μA (max) - allows two-channel precision amplification in battery-operated field instruments with <1 mW total dissipation |
| CMRR / PSRR | 115 dB / 5 μV/V (min/max) - rejects >10⁶:1 common-mode noise and supply ripple in noisy plant-floor environments |
Pinout & Package
OPA207ID is packaged in an 8-pin SOIC (D) body measuring 4.90 mm × 3.91 mm, optimized for automated assembly and thermal performance in industrial PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8 | No internal connection | Must be left floating or tied to ground; no electrical function - avoids unintended parasitic paths |
| 2 | Inverting input (–IN) | Differential input node for feedback networks; supports precision inverting configurations with matched resistor ratios |
| 3 | Non-inverting input (+IN) | High-impedance input node (1 GΩ || 1 pF) for sensor interfacing; low bias current minimizes voltage drop across high-Z sources |
| 4 | Negative supply (V–) | Reference for dual-supply operation; must be decoupled with 0.1 μF ceramic capacitor near pin |
| 6 | Output (OUT) | Rail-to-rail capable output driving 2 kΩ loads to within 125 mV of rails - enables direct interface to ADC references or DAC buffers |
| 7 | Positive supply (V+) | Primary power rail; supports wide range (±2.25 V to ±18 V); requires local 0.1 μF bypassing |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low offset drift | ±1 μV/°C max ensures <20 μV total offset shift over full industrial temperature range (–40°C to +125°C), eliminating recalibration in field-deployed transmitters |
| Rail-to-rail output | Swings to within 15 mV of either supply rail under no load - maximizes dynamic range for 16-bit+ ADCs without level-shifting circuitry |
| EMI rejection | EMIRR IN+ >100 dB at 900 MHz prevents RF rectification-induced offset shifts in wireless-adjacent industrial enclosures |
| Unity-gain stability | No external compensation required - simplifies layout and eliminates risk of oscillation in gain-of-1 sensor buffers and active filters |
| Phase reversal immunity | Guaranteed no output polarity inversion during input overdrive - prevents catastrophic control loop errors in closed-loop pressure/flow systems |

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 | Higher precision (1 µV offset, 0.015 µV/°C drift), but higher IQ (3.6 mA) and narrower supply range (±2.25 V to ±18 V same; single-supply min 4.5 V) | Better for metrology-grade lab equipment; less suitable for battery-powered or low-power industrial nodes | Select OPA211IDR only when sub-µV offset and <0.02 µV/°C drift are mandatory and power budget allows >9× higher quiescent current |
| AD8628ARZ | Zero-drift architecture (0.005 µV/°C), but lower GBW (2.5 MHz), higher noise (12 nV/√Hz), and limited rail-to-rail output swing (≥100 mV from rail) | Ideal for ultra-stable DC-coupled integrators; not recommended for fast-settling DAQ or wide-swing sensor buffers | Choose AD8628ARZ for zero-drift DC applications where speed and output swing are secondary; avoid for transmitter output stages requiring full rail utilization |
Compared with OPA207ID, OPA211IDR trades 9× higher power for 150× lower drift, while AD8628ARZ achieves near-zero drift at the cost of reduced output swing and higher broadband noise - making OPA207ID the optimal balance of low drift, rail-to-rail capability, and micropower operation for industrial transmitters and portable DAQ.

FAQ
What is the maximum input offset voltage specification for OPA207ID over temperature?
The OPA207ID has a maximum input offset voltage of ±150 μV over the industrial temperature range of –40°C to +85°C, and ±200 μV over the extended range of –40°C to +125°C. This specification is guaranteed by TI's production testing and applies to the SOIC (D) package variant. These values ensure predictable DC error budgets in transmitter calibration and DAQ system design without requiring post-manufacture trimming.
Does OPA207ID require external compensation for unity-gain stability?
No, the OPA207ID is internally compensated for unity-gain stability across its full operating range. It does not require external capacitors or resistors to maintain stability in G = 1 configurations such as voltage followers or non-inverting buffers. This eliminates layout sensitivity and reduces bill-of-materials cost - a key advantage over older precision op amps like OP-07 that demand careful compensation network design.
Can OPA207ID drive capacitive loads without oscillation?
Yes, the OPA207ID can safely drive up to 200 pF capacitive loads in unity-gain configuration without external isolation resistance. For loads exceeding 200 pF, a series resistor (RISO) of 25 Ω to 50 Ω between the output and the load restores stability and controls overshoot, as verified in TI's Figure 13 and Figure 14. This capability simplifies interface to ADC input capacitors and long PCB traces in industrial DAQ designs.
What is the recommended power supply decoupling for OPA207ID?
Texas Instruments recommends placing a 0.1 μF ceramic capacitor between each supply pin (V+ and V–) and ground, located as close as possible to the OPA207ID package. For noisy environments or mixed-signal PCBs, adding a 10 μF tantalum or aluminum electrolytic capacitor in parallel improves low-frequency supply rejection. These values are validated in TI's layout guidelines and ensure stable operation across the full ±2.25 V to ±18 V supply range.
How does OPA207ID compare to OP-177 in terms of key performance metrics?
The OPA207ID replaces OP-177 with measurable improvements: it offers twice the gain bandwidth (1 MHz vs. 0.6 MHz), ten times the slew rate (3.6 V/μs vs. 0.3 V/μs), half the quiescent current (375 μA vs. 750 μA), and lower 0.1–10 Hz noise (0.16 μVPP vs. 0.25 μVPP). Unlike OP-177, OPA207ID also features rail-to-rail output and guaranteed phase-reversal immunity - making it more robust in modern industrial signal chains.
