Product details
Overview
OPA4316IDR from Texas Instruments is a quad rail-to-rail input/output (RRIO), low-noise, low-power CMOS operational amplifier optimized for 1.8-V to 5.5-V single-supply operation. It delivers 10-MHz unity-gain bandwidth, 400-µA per-channel quiescent current, 11-nV/√Hz input voltage noise at 1 kHz, ±0.5-mV offset voltage, and ±5-pA input bias current - enabling precision signal conditioning in space-constrained, battery-powered systems such as portable medical sensors and barcode scanners.
For engineers reviewing the OPA4316IDR datasheet, OPA4316IDR pinout, OPA4316IDR application, or OPA4316IDR equivalent, this page provides verified package mapping (TSSOP-14), confirmed pin functions, real-world design meaning of key specs, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The OPA4316IDR integrates four independent, unity-gain stable amplifiers sharing a common 1.8–5.5-V supply range. Its CMOS input stage enables ultra-low input bias current (±5 pA typical) and rail-to-rail common-mode input range extending 0.2 V beyond both rails - critical for high-impedance sensor interfaces. The internal RFI-EMI filter suppresses high-frequency interference without external components.
Each amplifier features no phase reversal under overdrive, 6-V/µs slew rate, and 1-µs 0.1% settling time into 100-pF load. Output swing reaches within 15 mV of rails at 1.8 V (RL = 10 kΩ), supporting full dynamic range utilization in low-voltage data acquisition chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 10 MHz - supports stable closed-loop gain ≥1 with usable small-signal response up to audio and low-speed communication frequencies. |
| Quiescent Current / Channel | 400 µA - enables four amplifiers to operate continuously on <2-mA total supply current, ideal for coin-cell or energy-harvesting systems. |
| Input Voltage Noise Density | 11 nV/√Hz at 1 kHz - preserves SNR in low-level sensor amplification (e.g., thermopile, strain gauge) without requiring additional filtering. |
| Input Bias Current | ±5 pA - allows use with MΩ-level source impedances (e.g., pH electrodes, photodiode transimpedance stages) without significant offset drift. |
| Offset Voltage | ±0.5 mV (typ) - ensures ≤0.5% gain error in 1-V full-scale instrumentation paths without trimming. |
| Rail-to-Rail I/O | Input extends (V−) − 0.2 V to (V+) + 0.2 V; output swings within 15 mV of rails at 1.8 V - maximizes ADC utilization in single-supply 1.8-V systems. |
| Supply Range | 1.8 V to 5.5 V - interoperable across Li-ion, USB, and legacy 3.3/5-V rails without level-shifting. |
Pinout & Package
OPA4316IDR is housed in a 14-pin TSSOP (PW) package measuring 4.40 mm × 5.00 mm, with exposed thermal pad connected to V− for improved power dissipation and EMI immunity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 10 kΩ while maintaining rail-to-rail swing and 6-V/µs slew rate. |
| 2 | IN− A | Inverting input of Amplifier A - high-impedance node (10¹⁶ Ω || pF) compatible with passive filters and feedback networks. |
| 3 | IN+ A | Noninverting input of Amplifier A - accepts common-mode signals from (V−) − 0.2 V to (V+) + 0.2 V, enabling true single-supply sensor biasing. |
| 4 | V− | Negative supply or ground reference - connects to PCB ground plane and thermal pad; must be low-impedance for stability and noise rejection. |
| 5 | IN+ B | Noninverting input of Amplifier B - electrically isolated from other channels; shares same CMRR and PSRR performance as Channel A. |
| 6 | IN− B | Inverting input of Amplifier B - identical input structure to Pin 2; supports independent feedback configuration per channel. |
| 7 | OUT B | Amplifier B output - fully independent output stage; no crosstalk measured >100 dB at dc and <100 kHz. |
| 8 | V+ | Positive supply - supplies all four amplifiers; bypass capacitor (0.1 µF ceramic) required between Pins 8 and 4 for stability. |
| 9 | IN+ C | Noninverting input of Amplifier C - enables three-channel simultaneous sampling in multi-sensor systems (e.g., 3-axis IMU front-end). |
| 10 | IN− C | Inverting input of Amplifier C - matched input characteristics ensure consistent gain accuracy across all four channels. |
| 11 | OUT C | Amplifier C output - capable of driving capacitive loads up to 100 pF without oscillation due to internal compensation. |
| 12 | IN+ D | Noninverting input of Amplifier D - supports fourth independent signal path; identical electrical specs to Channels A–C. |
| 13 | IN− D | Inverting input of Amplifier D - maintains ±5-pA bias current and 11-nV/√Hz noise density across full temperature range. |
| 14 | OUT D | Amplifier D output - completes quad-channel functionality; output short-circuit protected to ±50 mA. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9054IDR | Higher 16-MHz GBW but 550-µA/ch IQ; no integrated RFI filter; ±1.6-mV VOS (max) | Better for higher-bandwidth active filters; less suitable for ultra-low-power or EMI-sensitive sensor nodes | Select TLV9054IDR only when bandwidth >10 MHz is required and supply current budget allows +37.5% increase per channel. |
| OPA491IDR | Zero-drift architecture; 0.025-µV/°C drift; 1.2-mV VOS (max); 1.2-MHz GBW; 120-µA/ch IQ | Superior for dc-critical applications (e.g., weigh scales, precision thermometry); insufficient bandwidth for audio or fast pulse detection | Choose OPA491IDR when long-term offset stability dominates over speed; avoid where >1-MHz closed-loop response is needed. |

FAQ
What is the maximum supply voltage for OPA4316IDR?
The OPA4316IDR operates over a total supply voltage range of 1.8 V to 5.5 V. This means the difference between V+ and V− pins must not exceed 5.5 V, and the minimum allowable difference is 1.8 V. Operation outside this range may cause permanent damage or undefined behavior. The device is fully specified across this range, including parameters like offset voltage, CMRR, and bandwidth.
Does OPA4316IDR support rail-to-rail input at 1.8-V supply?
Yes, the OPA4316IDR supports rail-to-rail input at 1.8-V supply: its common-mode input voltage range extends from (V−) − 0.2 V to (V+) + 0.2 V. At 1.8 V, this covers −0.2 V to +2.0 V, enabling direct connection to sensors referenced to ground or V+ without external level-shifting circuitry - a key enabler for single-supply 1.8-V system design.
What is the typical quiescent current per channel for OPA4316IDR?
The typical quiescent current per channel for OPA4316IDR is 400 µA at 25°C and 5 V supply. Over the full operating temperature range (−40°C to +125°C) and supply range (1.8 V to 5.5 V), the maximum specified quiescent current is 500 µA per channel. This low power consumption makes the OPA4316IDR suitable for always-on sensing applications in battery-powered equipment.
Is OPA4316IDR unity-gain stable?
Yes, the OPA4316IDR is unity-gain stable. Its internal compensation ensures stable operation with closed-loop gains of +1 or greater, without requiring external compensation components. This is confirmed in the datasheet's "Features" section and verified through phase margin measurements of ≥60° at unity gain - allowing straightforward implementation in buffer, follower, and basic gain configurations.
What package type is used for OPA4316IDR?
The OPA4316IDR uses a 14-pin TSSOP (Thin Shrink Small Outline Package), designated as PW package in Texas Instruments' ordering nomenclature. Its body dimensions are 4.40 mm × 5.00 mm, and it includes an exposed thermal pad on the underside that must be soldered to a grounded copper pour for optimal thermal performance and EMI suppression.
