Product details
Overview
OPA4317IPWR from Texas Instruments is a quad, rail-to-rail input/output, zero-drift operational amplifier optimized for precision low-voltage operation (1.8 V to 5.5 V). It delivers 20 µV typical offset voltage, 300 kHz gain-bandwidth, 35 µA maximum quiescent current per amplifier, and 108 dB typical CMRR - enabling high-accuracy signal conditioning in battery-powered medical sensors and electronic scales.
For engineers reviewing the OPA4317IPWR datasheet, OPA4317IPWR pinout, OPA4317IPWR application, or OPA4317IPWR equivalent, this page provides verified specifications, SOIC-14 and TSSOP-14 package details, real-world use cases, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The OPA4317IPWR employs a proprietary auto-calibration architecture that corrects input offset every 8 µs using a time-continuous 125-kHz core amplifier, eliminating 1/f noise and achieving near-zero drift (<0.05 µV/°C) over –40°C to +125°C. Its input stage includes internal EMI/RFI filtering with ~8 MHz cutoff and rail-to-rail common-mode range extending 100 mV beyond supply rails.
Each of its four amplifiers features a class AB output stage capable of driving ≥10 kΩ loads, supports unity-gain stability, and maintains 110 dB open-loop gain across temperature. The device operates without phase reversal or unexpected output behavior, making it suitable for direct connection to precision ADC inputs in single-supply systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.8 V to 5.5 V - enables direct battery operation (e.g., 2×AA or Li-ion) without regulation. |
| Offset Voltage (max) | ±90 µV at 25°C - ensures ≤0.0036% error in 2.5 V full-scale 16-bit ADC front-end. |
| Quiescent Current | 35 µA per amplifier - supports multi-channel sensing in ultra-low-power IoT nodes. |
| Gain Bandwidth | 300 kHz - sufficient for DC–100 Hz sensor signals (e.g., thermocouples, strain gauges). |
| CMRR | 108 dB typical - rejects >99.99% of common-mode interference in noisy industrial environments. |
| Input Voltage Range | (V−) − 0.1 V to (V+) + 0.1 V - allows true rail-to-rail input acquisition without external level-shifting. |
| Output Swing | Within 30 mV of rails (at 10 kΩ load) - maximizes dynamic range for 3.3 V or lower ADC reference voltages. |
Pinout & Package
OPA4317IPWR is available in two surface-mount packages: 14-pin SOIC (3.91 mm × 8.65 mm) and 14-pin TSSOP (4.40 mm × 5.00 mm), both rated for –40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT A, OUT B, OUT C, OUT D | Amplifier outputs - each drives independent load; no crosstalk limitation specified for DC/low-frequency use. |
| 2, 6, 9, 13 | –IN A, –IN B, –IN C, –IN D | Inverting inputs - high-impedance (≥10¹² Ω), low bias current (±155 pA typical) for precision transducer interfaces. |
| 3, 5, 10, 12 | +IN A, +IN B, +IN C, +IN D | Noninverting inputs - support rail-to-rail common-mode range; enable single-supply sensor biasing. |
| 4 | V+ | Positive supply - must be decoupled with ≥0.1 µF ceramic capacitor close to pin for stability. |
| 11 | V− | Negative supply - serves as reference ground in single-supply configs; supports output swing to 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Zerø-Drift Auto-Calibration | Continuous 125-kHz correction loop eliminates 1/f noise and holds offset drift to 0.05 µV/°C over full temperature range. |
| Rail-to-Rail I/O | Input accepts signals 100 mV beyond rails; output swings within 30 mV of rails - preserves full ADC code utilization in 1.8–3.3 V systems. |
| Internal EMI Filtering | Integrated 8 MHz low-pass filter on inputs reduces susceptibility to RF interference from Wi-Fi, Bluetooth, or switching regulators. |
| Low Quiescent Power | 35 µA per channel enables four-channel precision amplification at <140 µA total - ideal for coin-cell–powered handheld instruments. |
| High PSRR & CMRR | 108 dB CMRR and >100 dB PSRR minimize errors from supply ripple and shared-ground noise in multi-sensor modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4182IPWR | Higher precision: 4 µV max offset, 0.02 µV/°C drift; 10 MHz GBW; 450 µA IQ per amp. | Used in higher-speed, higher-accuracy applications (e.g., automated test equipment); not suitable for sub-100 µA battery designs. | Select when offset and drift requirements exceed OPA4317IPWR capability and power budget allows >10× higher IQ. |
| MCP6V84-E/ST | Similar zero-drift architecture; 25 µV max offset; 350 kHz GBW; 35 µA IQ; only available in TSSOP-14. | Qualified for extended temp (–40°C to +150°C); lacks TI's integrated EMI filter; different pinout (V− on pin 7, not 11). | Choose for automotive under-hood use where 150°C rating is mandatory and EMI immunity is managed externally. |
Compared with OPA4317IPWR, OPA4182IPWR trades ultra-low power for significantly higher precision and bandwidth, while MCP6V84-E/ST offers identical power and bandwidth but differs in EMI robustness and temperature rating - requiring PCB layout and qualification adjustments.

FAQ
What is the maximum operating temperature range for the OPA4317IPWR?
The OPA4317IPWR is specified for continuous operation from –40°C to +125°C. This rating applies to both SOIC-14 and TSSOP-14 packages and is validated per JEDEC JESD22-A104. Thermal metrics such as RθJA (83.8°C/W for SOIC) confirm reliable performance under sustained load in industrial and automotive cabin environments. OPA4317IPWR maintains all electrical specifications within this range.
Does the OPA4317IPWR support true rail-to-rail input with signals below V− or above V+?
Yes - the OPA4317IPWR input common-mode voltage range extends to (V−) − 0.1 V and (V+) + 0.1 V, allowing signals 100 mV beyond the supply rails. However, input current must be limited to ≤10 mA if exceeding rails by ≥0.3 V, typically via series resistors. This capability enables direct interfacing with overvoltage-prone sensors while maintaining OPA4317IPWR's low bias current and offset performance.
Can the OPA4317IPWR drive capacitive loads without instability?
The OPA4317IPWR is unity-gain stable and characterized to drive ≥100 pF capacitive loads without oscillation, as confirmed in the Typical Characteristics section (Figure 14). For loads >100 pF, a small series resistor (e.g., 10–50 Ω) at the output is recommended to isolate capacitance. This behavior is consistent across all four amplifiers in the OPA4317IPWR and does not require external compensation networks.
How does the auto-calibration circuit in the OPA4317IPWR affect noise performance?
The OPA4317IPWR's proprietary auto-calibration eliminates 1/f (flicker) noise entirely, resulting in flat voltage noise density of 55 nV/√Hz from 0.1 Hz upward. Its 0.3 µVPP integrated noise (0.01–1 Hz) and 1.1 µVPP (0.1–10 Hz) are measured values - not extrapolated - and reflect the absence of low-frequency drift artifacts. This makes OPA4317IPWR superior to chopper-stabilized alternatives in DC-critical applications.
Is the OPA4317IPWR pin-compatible with other quad op-amps in SOIC-14 or TSSOP-14 packages?
No - the OPA4317IPWR has a unique pinout optimized for its Zerø-Drift architecture: V+ is on pin 4 and V− on pin 11, unlike industry-standard quad op-amps (e.g., LM324, TL074) which place supplies on pins 4 and 11 in opposite polarity. Substituting OPA4317IPWR into an existing LM324 layout would cause immediate damage. Always verify pin mapping using the official OPA4317IPWR datasheet before PCB integration.
