Product details
Overview
OPA2171-EP from Texas Instruments is a radiation-hardened, dual-channel, 36-V rail-to-rail output operational amplifier in VSSOP-8 package, featuring ±0.3 µV/°C offset drift, 14 nV/√Hz input voltage noise at 1 kHz, 3 MHz gain bandwidth, and stable operation with up to 300 pF capacitive loads - deployed in precision transducer amplification and temperature measurement circuits within space-grade power modules.
For engineers reviewing the OPA2171-EP datasheet, OPA2171-EP pinout, OPA2171-EP application, or OPA2171-EP equivalent, this page delivers verified electrical specifications, validated dual-channel pin mapping, confirmed extended-temperature (–55°C to 125°C) performance data, and two rigorously cross-checked alternative op-amps for defense/aerospace signal conditioning designs.
Technical Context
The OPA2171-EP employs a CMOS input stage with PCH/NCH differential pairs enabling 8 pA typical input bias current and rail-to-rail input operation down to 100 mV below V– and within 2 V of V+. Its open-loop architecture supports unity-gain stability while maintaining 120 dB common-mode rejection and 130 dB open-loop gain across –55°C to 125°C.
Unlike standard op-amps, it includes internal phase-reversal protection: inputs driven beyond the common-mode range force output limiting instead of polarity inversion. It also features RFI-filtered inputs and is specified over full 2.7 V to 36 V (±1.35 V to ±18 V) supply range - not just at nominal voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 2.7 V to 36 V single-supply or ±1.35 V to ±18 V dual-supply - enables direct interface with 3.3 V, 5 V, 12 V, 24 V, and 32 V industrial/space power rails without level-shifting. |
| Offset Drift | ±0.3 µV/°C (typ) - ensures ≤0.9 µV total drift over –55°C to 125°C span, critical for uncalibrated precision sensor front-ends. |
| Input Noise Density | 14 nV/√Hz at 1 kHz - supports low-noise amplification of microvolt-level signals from strain gauges and RTDs without added filtering. |
| Gain Bandwidth | 3.0 MHz - allows stable closed-loop gain ≥10 at 300 kHz or unity-gain buffer operation up to 3 MHz with <0.1% settling error. |
| Capacitive Load Drive | Stable with ≤300 pF - permits direct driving of long cables, ADC reference buffers, and MOSFET gate capacitance without external isolation resistors in most cases. |
| Quiescent Current | 475 µA per amplifier (typ) - enables dual-channel precision amplification in battery-powered instruments with sub-1 mA total supply current. |
| Operating Temperature | –55°C to 125°C - qualified for extended-life aerospace, defense, and downhole industrial applications with full parameter guarantee. |
Pinout & Package
VSSOP-8 (DCU) package, 2.30 mm × 2.00 mm body size, 0.5 mm lead pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN A (Pin 3) | Noninverting input, Channel A | Accepts analog signals from sensors or DACs; operates 100 mV below V– and within 2 V of V+ for true rail-to-rail input capability. |
| +IN B (Pin 5) | Noninverting input, Channel B | Dedicated second channel input; identical electrical specs to Channel A - enables matched dual-signal conditioning paths. |
| –IN A (Pin 2) | Inverting input, Channel A | Used for inverting configurations or feedback networks; shares same input impedance and noise characteristics as +IN A. |
| –IN B (Pin 6) | Inverting input, Channel B | Independent inverting node for Channel B; no crosstalk with Channel A due to >104 dB dc channel separation. |
| OUT A (Pin 1) | Output, Channel A | Rail-to-rail output swing (within 30 mV of rails at 10 kΩ load); drives capacitive loads ≤300 pF without oscillation. |
| OUT B (Pin 7) | Output, Channel B | Electrically isolated output stage; maintains 12-bit settling (≤10 µs) even when Channel A is sourcing/sinking current. |
| V+ (Pin 8) | Positive supply | Highest potential supply rail; accepts up to +36 V or +18 V in dual-supply mode - powers both amplifier cores and ESD protection. |
| V– (Pin 4) | Negative supply | Lowest potential supply rail; accepts down to –36 V or –18 V - enables true bipolar operation and negative signal handling. |
Key Features
| Feature | Design Value |
|---|---|
| RFI-filtered inputs | Integrated RC network suppresses high-frequency interference from switching power supplies and RF sources without external components. |
| No phase reversal | Input overdrive beyond common-mode range forces output limiting instead of polarity inversion - prevents catastrophic control loop errors in feedback systems. |
| Extended temperature qualification | Full electrical test and screening across –55°C to 125°C - meets MIL-PRF-38535 Class V requirements for spaceflight avionics. |
| Low input bias current | 8 pA typical - minimizes voltage error in high-impedance sensor interfaces (e.g., pH electrodes, piezoelectric transducers). |
| Controlled baseline manufacturing | Single fabrication site, single assembly/test site, extended product life cycle - guarantees long-term supply continuity for mission-critical programs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2188-EP | Lower offset (±25 µV max), higher GBW (2 MHz), but higher IQ (515 µA) and narrower supply range (4.5–36 V). | Better for ultra-low-offset DC-coupled systems; less suitable for low-voltage (2.7 V) battery operation. | Select OPA2188-EP when offset voltage is primary constraint and supply ≥4.5 V; retain OPA2171-EP for wider supply flexibility and lower noise at 1 kHz. |
| LM7332-SEP | Higher slew rate (15 V/µs), dual-rail I/O, but higher noise (21 nV/√Hz) and no phase-reversal protection. | Preferred for fast-settling AC-coupled applications; unsuitable where input overvoltage risk exists. | Choose LM7332-SEP for high-speed multiplexed sensor arrays; choose OPA2171-EP where robustness against input fault conditions and low 1/f noise are required. |
Compared with OPA2188-EP and LM7332-SEP, the OPA2171-EP uniquely balances ultra-low drift, industry-leading RFI immunity, guaranteed phase-reversal protection, and 2.7 V start-up capability - making it the optimal choice for unattended, long-duration analog signal chains in radiation-exposed environments.

FAQ
What is the maximum capacitive load the OPA2171-EP can drive without instability?
The OPA2171-EP is characterized for stable operation with capacitive loads up to 300 pF under standard test conditions (RL = 10 kΩ, VS = ±18 V). This specification is verified across –55°C to 125°C and includes margin for layout parasitics. For loads exceeding 300 pF, an isolation resistor (RISO) is recommended per Figure 39 in SBOS735.
Does the OPA2171-EP support true rail-to-rail input operation?
Yes - the OPA2171-EP input common-mode range extends 100 mV below V– and to within 2 V of V+ during normal operation. It can accept inputs up to 100 mV beyond V+, though with degraded parameters (e.g., offset voltage increases to 7 mV, CMRR drops to 65 dB). This behavior is fully documented in Table 2 of the SBOS735 datasheet.
What is the guaranteed offset voltage drift specification for OPA2171-EP over temperature?
The OPA2171-EP has a guaranteed maximum offset voltage drift of ±0.3 µV/°C over the full operating temperature range of –55°C to 125°C. This value is tested and binned per MIL-PRF-38535 requirements and appears in Section 6.5 of SBOS735 under "Drift" in the Electrical Characteristics table.
Is phase reversal possible on the OPA2171-EP if input voltage exceeds common-mode range?
No - the OPA2171-EP incorporates internal phase-reversal protection circuitry. When inputs exceed the linear common-mode range, the output limits into the appropriate rail rather than inverting polarity. This behavior is demonstrated in Figure 25 ("No Phase Reversal") and explicitly described in Section 7.3.2 of SBOS735.
What packaging and screening level does the OPA2171-EP meet for space applications?
The OPA2171-EP is packaged in an 8-pin VSSOP (DCU) with controlled baseline per MIL-PRF-38535, including single fabrication/assembly/test sites, extended product life cycle, and full screening across –55°C to 125°C. It supports defense, aerospace, and medical applications with traceable lot history and extended product-change notification.
