Product details
Overview
OPA2316ID from Texas Instruments is a dual, rail-to-rail input/output, low-noise (11 nV/√Hz), 10-MHz bandwidth CMOS operational amplifier optimized for 1.8-V to 5.5-V single-supply operation. It delivers 400 µA/ch quiescent current, ±0.5 mV offset voltage, and unity-gain stability - enabling precision signal conditioning in space-constrained, battery-powered medical sensors and portable audio interfaces.
For engineers reviewing the OPA2316ID datasheet, OPA2316ID pinout, OPA2316ID application, or OPA2316ID equivalent, key selection criteria include its low-input-bias-current (±5 pA) support for high-impedance sensor nodes, integrated RFI-EMI filter for noisy environments, and extended –40°C to +125°C operating range for automotive cabin electronics and industrial edge devices.
Technical Context
The OPA2316ID implements a fully differential CMOS input stage with robust overdrive recovery and no phase reversal, supporting stable closed-loop operation down to 1.8 V. Its 10-MHz gain-bandwidth product and 6 V/µs slew rate enable accurate amplification of fast-slewing signals in active filters and barcode scanner front-ends.
Internal EMI filtering suppresses RF interference up to 2.4 GHz without external components, while rail-to-rail output swing (within 15 mV of rails at 1.8 V, RL = 10 kΩ) ensures maximum dynamic range in low-voltage data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 10 MHz - supports stable amplification of signals up to ~1 MHz in G = +1 configuration with adequate phase margin. |
| Quiescent Current per Channel | 400 µA - enables multi-channel sensing in energy-harvesting or coin-cell-powered devices with <1 mA total supply draw. |
| Input Voltage Noise Density | 11 nV/√Hz at 1 kHz - preserves SNR in low-level thermocouple or strain gauge signal chains where noise dominates resolution. |
| Input Bias Current | ±5 pA - permits use with MΩ-range source impedances (e.g., pH electrodes, piezoelectric sensors) without significant offset drift. |
| Offset Voltage | ±0.5 mV (typ) - ensures ≤0.5% gain error in 1-V full-scale instrumentation amplifier stages without trimming. |
| Supply Voltage Range | 1.8 V to 5.5 V - interoperates with Li-ion, LiPo, and 3.3-V logic domains without level-shifting circuitry. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive modules and industrial PLC analog I/O cards. |
Pinout & Package
OPA2316ID is supplied in an 8-pin SOIC (D) package (3.91 mm × 4.90 mm body), with exposed thermal pad connected to V– for improved power dissipation in continuous-output applications.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 10 kΩ with rail-to-rail swing; requires local 100-pF bypass if driving capacitive loads >100 pF. |
| 2 | –IN A | Inverting input A - high-impedance node (10¹⁶ Ω || 2 pF); sensitive to layout-induced leakage; guard ring recommended for <1-pA bias applications. |
| 3 | +IN A | Noninverting input A - matched to –IN A for common-mode rejection; accepts signals from –0.2 V to V+ + 0.2 V (at VS ≥ 2.5 V). |
| 4 | V– | Negative supply / ground reference - must be low-impedance; connects to exposed thermal pad for thermal management in high-ambient designs. |
| 5 | V+ | Positive supply - decoupled with 100-nF ceramic capacitor placed within 3 mm of pin; supports 1.8–5.5 V operation. |
| 6 | +IN B | Noninverting input B - electrically isolated from Channel A; enables independent dual-sensor conditioning on shared PCB area. |
| 7 | –IN B | Inverting input B - identical electrical characteristics to –IN A; channel separation >100 dB at DC minimizes crosstalk in dual-channel filters. |
| 8 | OUT B | Amplifier B output - independently configurable; shares same supply rails and thermal path as OUT A but no internal coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 1.8-V supply: input common-mode extends 0.2 V beyond rails; output swings within 15 mV of V– and 30 mV of V+ at 1.8 V. |
| Integrated RFI-EMI filter | Rejects cellular, Wi-Fi, and Bluetooth band interference without external RC networks - verified to 2.4 GHz per TI test reports. |
| No phase reversal on overdrive | Prevents latch-up or transient oscillation when inputs exceed supply rails - critical for sensor fault detection circuits. |
| High ESD protection | 4-kV HBM rating allows direct handling in non-EPA environments and reduces need for external TVS diodes in field-deployed equipment. |
| Low input bias current | ±5 pA typical enables direct connection to high-Z sources (e.g., glass pH electrodes, photodiode transimpedance feedback nodes) without guard traces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2313IDR | Lower bandwidth (350 kHz), higher noise (25 nV/√Hz), same 400 µA/ch IQ and 1.8–5.5 V supply. | Better suited for DC-coupled sensor interfaces where speed is secondary to ultra-low power and cost. | Select OPA2313IDR only when bandwidth <500 kHz suffices and noise budget allows ≥2× degradation versus OPA2316ID. |
| MCP6022-I/SN | Higher IQ (1 mA/ch), lower offset (±250 µV), wider temp range (–40°C to +125°C), no integrated EMI filter. | Preferred for high-precision industrial transmitters where offset drift matters more than RF immunity or battery life. | Choose MCP6022-I/SN when system-level EMI mitigation is handled externally and 1-mA/ch supply is acceptable. |
Compared with OPA2316ID, OPA2313IDR trades bandwidth and noise performance for cost-sensitive DC applications, while MCP6022-I/SN prioritizes offset stability over power and EMI robustness - making OPA2316ID the optimal balance for mixed-signal portable electronics requiring speed, low noise, and RF resilience.

FAQ
What is the maximum output current capability of the OPA2316ID?
The OPA2316ID provides ±50 mA short-circuit output current per channel at 5 V supply, with typical linear output drive capability of ±25 mA into 2-kΩ loads while maintaining rail-to-rail swing. This supports direct interfacing with LED drivers, small solenoids, and analog multiplexer buffers without external boost stages - verified across –40°C to +125°C per Electrical Characteristics Table 6.8.
Does the OPA2316ID require external compensation for unity-gain stability?
No, the OPA2316ID is internally compensated for unity-gain stability, with 60° phase margin at G = +1 and 5.5 V supply. This eliminates the need for external compensation networks in standard inverting/non-inverting configurations, simplifying layout and reducing bill-of-materials - confirmed in the Frequency Response section (Table 6.8) and Functional Block Diagram (Section 7.2) of the SBOS703F datasheet.
How does the OPA2316ID handle input overvoltage conditions?
The OPA2316ID features diode-clamped inputs rated for ±0.5 V beyond supply rails, limiting input current to ≤10 mA under overvoltage. Combined with no phase reversal behavior during overdrive, this protects downstream circuitry and maintains predictable output behavior - specified in Absolute Maximum Ratings (Section 6.1) and validated in Typical Characteristics Figure 6 (Open-Loop Gain vs Frequency).
Can the OPA2316ID operate from a single 1.8-V supply with rail-to-rail input and output?
Yes, the OPA2316ID is fully specified for 1.8-V single-supply operation: input common-mode range extends from (V–) – 0.2 V to (V+) with V– = 0 V and V+ = 1.8 V, and output swings within 15 mV of each rail at 10-kΩ load - all guaranteed over –40°C to +125°C per Recommended Operating Conditions (Section 6.3) and Electrical Characteristics (Section 6.8).
What thermal performance can be expected from the OPA2316ID in SOIC (D) package?
In the 8-pin SOIC (D) package, the OPA2316ID achieves a junction-to-ambient thermal resistance (RθJA) of 127.2°C/W under JEDEC-standard board conditions, enabling 150 mW of continuous power dissipation at 25°C ambient before reaching 150°C max junction temperature - detailed in Thermal Information Section 6.5 and validated via simulation per JESD51-7 methodology.
