Product details
Overview
OPA207IDBVT from Texas Instruments is a precision rail-to-rail output operational amplifier in a 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. It replaces legacy OP-07/OP-77/OP-177 in high-accuracy analog input modules and pressure transmitters where low noise and wide supply range (±2.25 V to ±18 V) are critical.
For engineers reviewing the OPA207IDBVT datasheet, OPA207IDBVT pinout, OPA207IDBVT application, or OPA207IDBVT equivalent, key selection criteria include verified 0.1–10 Hz noise (0.16 µVPP), rail-to-rail output swing (≤40 mV from rail, no load), CMRR ≥115 dB, PSRR ≤5 µV/V, and confirmed stability in unity-gain configurations without phase reversal.
Technical Context
The OPA207IDBVT 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 - unlike CMOS/JFET op amps whose bias current doubles per 10°C rise. Its rail-to-rail output stage uses series-limiting resistors for consistent short-circuit protection and maintains >120 dB open-loop gain even at full output swing.
A proprietary slew-boost architecture enables 3.6 V/µs slew rate while consuming only 375 µA per amplifier. EMI rejection ratio (EMIRR IN+) exceeds 80 dB at 100 MHz, mitigating RF rectification-induced offset shifts in noisy industrial environments - a feature validated in TI Application Report SLOA199.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset voltage | ±130 µV max (TA = –40°C to 125°C); ensures <0.01% error in 12-bit DAQ systems at 2.5 V reference |
| Drift | ±1.1 µV/°C max; contributes <±0.13 mV total drift over 125°C range - critical for uncalibrated temperature transmitters |
| Gain bandwidth | 1 MHz typical; supports stable closed-loop operation up to 100 kHz with G=10, enabling fast sensor signal conditioning |
| Output swing | ≤40 mV from rail (no load, TA = 25°C); delivers true rail-to-rail dynamic range in single-supply battery test fixtures |
| Quiescent current | 375 µA max per amplifier; enables dual-op-amp designs in portable DAQ with <1 mW total dissipation at ±15 V |
| CMRR | 115 dB min (–40°C to 125°C); rejects common-mode noise from 4–20 mA loop-powered sensors without calibration loss |
| 0.1–10 Hz noise | 0.16 µVPP; meets <1 µVPP requirement for 24-bit sigma-delta ADC front-ends in precision analog input modules |
Pinout & Package
SOT-23 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, gull-wing leads. RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Output | Rail-to-rail voltage source capable of sourcing/sinking ±40 mA; requires no external compensation for unity-gain stability |
| 2 - V– | Negative supply | Connects to lowest system potential; supports operation down to –2.25 V; internal ESD diodes clamp to V– if overdriven |
| 3 - +IN | Non-inverting input | High-impedance node (1 GΩ || 1 pF); primary EMI entry point - EMIRR IN+ >80 dB at 100 MHz validated |
| 4 - –IN | Inverting input | Differential input terminal; matched to +IN for <0.13 nA max offset current; internal 10 kΩ series resistors limit fault current to 10 mA |
| 5 - V+ | Positive supply | Connects to highest system potential; accepts up to +18 V; quiescent current stable across full ±2.25 V to ±18 V range |
Key Features
| Feature | Design Value |
|---|---|
| Input bias current cancellation | Super-beta bipolar inputs + internal cancellation yield ≤2.8 nA max IB across –40°C to +125°C - avoids thermal runaway in high-Z pH sensor buffers |
| Rail-to-rail output stage | Output swings within 40 mV of either rail under no load; maintains >120 dB AOL at 99% of supply range - eliminates level-shifting in single-supply battery testers |
| Slew-boost architecture | 3.6 V/µs slew rate achieved at 375 µA IQ - enables <5.4 µs settling to 0.01% for 10-V step, critical for fast-settling DAQ channels |
| No phase reversal | Internally compensated for unity-gain stability; immune to output polarity inversion during input overdrive - prevents latch-up in pressure transmitter feedback loops |
| EMI rejection | EMIRR IN+ >80 dB at 100 MHz; suppresses GSM/ISM-band RF rectification that causes DC offset drift in industrial control cabinets |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDBVT | Lower noise (3.8 nV/√Hz vs. 7.5 nV/√Hz @1 kHz), higher IQ (3.6 mA), no rail-to-rail output (1.5 V headroom) | Better for low-noise photodiode amps; unsuitable for single-supply 0–5 V sensor interfaces requiring rail-to-rail swing | Choose OPA211IDBVT only when sub-4 nV/√Hz noise outweighs power and output swing constraints. |
| LTC2050CS5#TRMPBF | Zero-drift architecture (0.005 µV/°C drift), higher cost, 1.1 mA IQ, SOIC-5 package only | Required for <0.01 µV/°C drift in metrology-grade calibrators; overqualified for industrial transmitter use cases | Select LTC2050CS5#TRMPBF only for applications demanding sub-10 nV offset drift - not for cost-sensitive industrial DAQ. |
Compared with OPA207IDBVT, OPA211IDBVT trades rail-to-rail output and 10× lower IQ for improved noise floor, while LTC2050CS5#TRMPBF achieves near-zero drift at 3× higher power and cost - making OPA207IDBVT the optimal balance for industrial analog input modules and transmitters.

FAQ
What is the maximum input differential voltage rating for OPA207IDBVT?
The OPA207IDBVT has an absolute maximum differential input voltage of ±1 V. Exceeding this risks permanent damage to the internal ESD protection diodes. This rating is independent of supply voltage and applies across the full –55°C to +150°C storage temperature range per the SBOS826D datasheet Section 6.1.
Does OPA207IDBVT require external compensation capacitors for stability?
No, the OPA207IDBVT is unity-gain stable and does not require external compensation. Its internal compensation ensures phase margin >60° across all gains and load conditions up to 200 pF, as verified in Figure 13–14 of the SBOS826D datasheet. Adding external capacitors may degrade step response.
Can OPA207IDBVT drive capacitive loads directly?
Yes, OPA207IDBVT can drive up to 200 pF capacitive loads without oscillation, as specified in Section 6.5. For loads >200 pF, a series isolation resistor (RISO) of 25–50 Ω is recommended - Figure 13 shows <5% overshoot at 200 pF with RISO = 0 Ω, confirming robust capacitive drive capability.
What is the actual 0.1–10 Hz noise performance of OPA207IDBVT?
The OPA207IDBVT delivers 0.16 µVPP (0.024 µVRMS) integrated noise from 0.1 Hz to 10 Hz, measured at ±15 V supply with RL = 2 kΩ. This value is guaranteed across the –40°C to +125°C operating range and is critical for low-frequency sensor applications like strain gauge bridges.
Is OPA207IDBVT pin-compatible with OP-07 or OP-177?
No, OPA207IDBVT is not pin-compatible with OP-07 or OP-177. It uses a 5-pin SOT-23 (DBV) package with pinout: 1=OUT, 2=V–, 3=+IN, 4=–IN, 5=V+. In contrast, OP-07/OP-177 use 8-pin DIP/SOIC packages with different pin assignments and require external nulling components - PCB redesign is required for replacement.
