Product details
Overview
OPA2316SIRUGR from Texas Instruments is a dual-channel, rail-to-rail input/output (RRIO), low-power CMOS operational amplifier with shutdown control, designed for precision signal conditioning in space-constrained, battery-powered systems. It delivers 10-MHz unity-gain bandwidth, 400 µA per channel quiescent current, ±0.5 mV offset voltage, and 11 nV/√Hz input voltage noise at 1 kHz - enabling high-fidelity amplification in portable medical sensors and barcode scanner front-ends.
For engineers reviewing the OPA2316SIRUGR datasheet, OPA2316SIRUGR pinout, OPA2316SIRUGR application, or OPA2316SIRUGR equivalent, this page provides verified package mapping (10-pin X2QFN, 1.5 mm × 2.0 mm), confirmed dual-channel shutdown timing (tON = 13 µs full, tOFF = 5 µs), rail-to-rail output swing within 15 mV of rails at 1.8 V, and validated thermal metrics (RθJA = 158 °C/W) - all critical for low-voltage, thermally sensitive embedded designs.
Technical Context
The OPA2316SIRUGR integrates two independent, unity-gain stable op-amps with internal RFI-EMI filtering and no phase reversal under overdrive. Its CMOS input stage enables ±5 pA input bias current and supports MΩ-level source impedances, while the shutdown function disables both amplifiers simultaneously to reduce total supply current to ≤1 µA.
It operates across 1.8 V to 5.5 V total supply range (±0.9 V to ±2.75 V), maintains ≥70 dB CMRR over –40°C to +125°C, and achieves 6 V/µs slew rate with 1 µs 0.1% settling time (2-V step, 100-pF load), making it suitable for fast, low-distortion analog signal paths in automotive and industrial sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 10 MHz - supports stable closed-loop gain ≥1 with sufficient phase margin for anti-aliasing filters and active sensor interfaces. |
| Quiescent Current / Channel | 400 µA - enables >100-hour operation on coin-cell batteries in always-on sensor nodes without compromising bandwidth. |
| Input Offset Voltage | ±0.5 mV (typ) - ensures <0.1% error in 0.5-V full-scale medical sensor outputs without trimming. |
| Input Voltage Noise Density | 11 nV/√Hz at 1 kHz - preserves SNR in low-level piezoelectric or thermopile signal chains. |
| Rail-to-Rail Output Swing | Within 15 mV of rails at 1.8 V - maximizes dynamic range in single-supply, low-voltage data acquisition. |
| Shutdown Quiescent Current | ≤1 µA (per device) - reduces system standby power by >99.7% versus active mode. |
| Common-Mode Rejection Ratio | ≥70 dB (–40°C to +125°C) - rejects EMI-coupled common-mode interference in noisy automotive environments. |
Pinout & Package
OPA2316SIRUGR is housed in a 10-pin X2QFN (RUG) package measuring 1.50 mm × 2.00 mm with an exposed thermal pad on the underside, requiring connection to V– for optimal thermal performance and ESD robustness.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load; rail-to-rail swing supports full 1.8-V supply utilization. |
| 2 | –IN A | Inverting input for Amplifier A - high-impedance CMOS node; accepts signals up to V– – 0.2 V and V+ + 0.2 V. |
| 3 | +IN A | Noninverting input for Amplifier A - matched to –IN A for low input offset; used in buffer or noninverting gain configurations. |
| 4 | V– | Negative supply or ground reference - connects to PCB ground plane and thermal pad; defines lower rail for single/dual supply operation. |
| 5 | SHDN A | Channel A shutdown control - logic low disables A amplifier; high impedance when unasserted (≤3.5 pA bias). |
| 6 | SHDN B | Channel B shutdown control - independent enable/disable of second amplifier; allows partial power-down. |
| 7 | +IN B | Noninverting input for Amplifier B - electrically identical to +IN A; enables dual-sensor or differential pair processing. |
| 8 | –IN B | Inverting input for Amplifier B - matched to +IN B; supports fully differential or dual-single-ended topologies. |
| 9 | OUT B | Amplifier B output - isolated from OUT A; enables simultaneous processing of two analog channels. |
| 10 | V+ | Positive supply - accepts 1.8 V to 5.5 V; internal regulation ensures stable biasing across voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Operates with input common-mode range extending 0.2 V beyond rails and output swing within 15 mV of rails at 1.8 V - eliminates level-shifting in ultra-low-voltage systems. |
| Integrated RFI-EMI filter | Rejects high-frequency interference from wireless modules or switching regulators without external RC networks - reduces board area and design risk. |
| No phase reversal on overdrive | Prevents latch-up or erroneous output transitions when inputs exceed supply rails - improves reliability in transient-prone automotive and industrial environments. |
| 4-kV HBM ESD protection | Withstands electrostatic discharge events during handling and assembly without damage - lowers field failure rates in high-volume manufacturing. |
| Low input bias current (±5 pA) | Minimizes voltage error across high-impedance sensor elements (e.g., pH electrodes, photodiodes) - avoids signal degradation without guard traces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-power, RRIO operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2313IDGKR | Lower bandwidth (350 kHz), higher offset (±1.25 mV), no shutdown, same 10-pin VSSOP package. | Suitable for DC-coupled sensor buffers where speed is secondary to ultra-low cost and simplicity. | Select when bandwidth <1 MHz suffices and shutdown functionality is unnecessary. |
| TLV9062IDSGR | Higher bandwidth (10 MHz), lower noise (16 nV/√Hz), no integrated RFI filter, 8-pin WSON package. | Better for high-speed active filters but lacks EMI hardening; requires external filtering in noisy environments. | Choose when maximum slew rate (6.5 V/µs) and open-loop gain (140 dB) are prioritized over EMI immunity. |
Compared with OPA2316SIRUGR, OPA2313IDGKR trades bandwidth and shutdown for cost reduction, while TLV9062IDSGR offers matching speed but requires external RFI mitigation - making OPA2316SIRUGR optimal for compact, EMI-resilient, battery-operated dual-channel sensing.

FAQ
What is the operating temperature range of the OPA2316SIRUGR?
The OPA2316SIRUGR is specified for continuous operation from –40°C to +125°C, with absolute maximum ratings extending to –55°C to +150°C. This extended industrial temperature range ensures reliable performance in automotive cabin modules, outdoor industrial sensors, and medical wearables exposed to wide ambient variations - all while maintaining ±0.5 mV offset voltage and ≥70 dB CMRR across the full span.
Does the OPA2316SIRUGR support single-supply operation?
Yes, the OPA2316SIRUGR supports true single-supply operation from 1.8 V to 5.5 V. Its rail-to-rail input extends 0.2 V beyond the supply rails, and its rail-to-rail output swings within 15 mV of V– and V+ at 1.8 V - enabling direct interfacing with 1.8-V ADCs and microcontrollers without level-shifting circuitry. The V– pin serves as ground reference in single-supply configurations.
How does the shutdown feature work on the OPA2316SIRUGR?
The OPA2316SIRUGR features two independent shutdown pins (SHDN A and SHDN B). Driving either pin low disables its respective amplifier channel; driving both low places the entire device in full shutdown, reducing total quiescent current to ≤1 µA. Enable time is 13 µs (full shutdown) and 10 µs (partial), with disable time of 5 µs - allowing rapid power cycling in duty-cycled sensor systems without compromising signal integrity.
What package type is used for the OPA2316SIRUGR?
The OPA2316SIRUGR uses the RUG package: a 10-pin X2QFN measuring 1.50 mm × 2.00 mm with an exposed thermal pad on the underside. This ultra-compact, leadless package requires soldering the thermal pad to V– for optimal thermal dissipation (RθJA = 158 °C/W) and enhanced ESD robustness - ideal for space-constrained portable and wearable electronics.
Is the OPA2316SIRUGR unity-gain stable?
Yes, the OPA2316SIRUGR is unity-gain stable with ≥60° phase margin at G = +1. This allows direct use in voltage follower, noninverting amplifier, and active filter configurations without external compensation. Its stability is maintained across the full 1.8 V–5.5 V supply range and –40°C to +125°C temperature range - simplifying design validation for precision analog circuits.
