Product details
Overview
OPA2316SIDGS from Texas Instruments is a dual, rail-to-rail input/output, 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/ch 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 medical sensors and portable instrumentation.
For engineers reviewing the OPA2316SIDGS datasheet, OPA2316SIDGS pinout, OPA2316SIDGS application, or OPA2316SIDGS equivalent, this page provides verified package mapping (10-pin MSOP), validated dual-channel shutdown control timing (tON = 13 µs, tOFF = 5 µs), rail-to-rail output swing down to 15 mV from rails at 1.8 V, and confirmed ESD robustness (±4-kV HBM).
Technical Context
The OPA2316SIDGS integrates two independent amplifiers with internal RFI-EMI filtering, no phase reversal under overdrive, and unity-gain stability across its full 1.8–5.5-V supply range. Its CMOS input stage enables ultra-low input bias current (±5 pA) and high input impedance (1016 Ω differential), supporting high-impedance sensor interfaces up to MΩ source impedances.
Each channel features independent shutdown control (SHDN_A/SHDN_B), allowing selective power gating. Full shutdown draws only 0.01 µA per device, while partial shutdown (one channel active) maintains 345 µA total quiescent current - preserving system-level power efficiency without compromising signal path readiness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 10 MHz - supports stable closed-loop operation up to 10-MHz signal frequencies with G = +1 configuration. |
| Quiescent Current per Channel | 400 µA - enables dual-channel operation on coin-cell or Li-ion battery for >1-year runtime in always-on sensor nodes. |
| Input Voltage Noise Density | 11 nV/√Hz at 1 kHz - preserves SNR in low-level transducer signals (e.g., thermopile, strain gauge) without added gain-stage noise. |
| Input Bias Current | ±5 pA - permits use with >10-MΩ source impedances without significant DC error or settling time degradation. |
| Offset Voltage | ±0.5 mV (typ) - ensures ≤0.1% gain error in 5-V full-scale instrumentation amplifier front-ends. |
| Rail-to-Rail Output Swing | 15 mV from rails at 1.8 V - maximizes dynamic range in low-voltage ADC driver applications with 12-bit+ resolution. |
| Shutdown Current (Full) | 0.01 µA - reduces standby power to negligible levels in intermittent-sampling systems (e.g., wearable biosensors). |
Pinout & Package
OPA2316SIDGS is housed in a 10-pin MSOP (DGS) package measuring 3.00 mm × 3.00 mm with 0.5-mm pitch. The exposed thermal pad on the underside must be connected to V– for optimal thermal performance and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next-stage input; rail-to-rail swing supports full 1.8-V supply utilization. |
| 2 | –IN A | Inverting input of Amplifier A - used in inverting configurations or feedback networks; matched to +IN A for common-mode rejection. |
| 3 | +IN A | Noninverting input of Amplifier A - accepts high-impedance sensor signals; ±5-pA bias current minimizes loading error. |
| 4 | V– | Negative supply / ground reference - connects to system ground in single-supply designs; thermal pad tied here for heat dissipation. |
| 5 | SHDN A | Shutdown control for Amplifier A - logic low disables output (high-Z), logic high enables; tOFF = 5 µs ensures fast power-down. |
| 6 | SHDN B | Shutdown control for Amplifier B - independent of SHDN A; enables asymmetric power management in multi-channel systems. |
| 7 | +IN B | Noninverting input of Amplifier B - electrically isolated from Amplifier A; supports dual-sensor acquisition with <10-µV crosstalk. |
| 8 | –IN B | Inverting input of Amplifier B - matches pin 2 characteristics; allows identical feedback network design for both channels. |
| 9 | OUT B | Amplifier B output - identical AC/DC specs to OUT A; supports simultaneous dual-channel signal processing without inter-channel delay skew. |
| 10 | V+ | Positive supply - accepts 1.8–5.5-V input; internal regulation ensures stable biasing across voltage range without external components. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full 1.8-V supply utilization in single-ended ADC drivers and battery-monitoring circuits without level-shifting. |
| Internal RFI-EMI filter | Rejects >30-dB conducted RF interference at 900 MHz and 2.4 GHz - eliminates need for external ferrite beads in noisy industrial environments. |
| No phase reversal on overdrive | Prevents latch-up and transient spikes during input overload - critical for fault-tolerant automotive sensor interfaces (e.g., wheel speed). |
| 4-kV HBM ESD protection | Withstands handling and board assembly without additional protection diodes - reduces BOM count in handheld medical devices. |
| Extended temperature range | –40°C to +125°C operation supports deployment in under-hood automotive ECUs and industrial motor controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2313IDGKR | Lower bandwidth (350 kHz), higher noise (25 nV/√Hz), no shutdown pins, SOIC-8 package. | Suitable for DC-coupled sensor buffering where speed and power are secondary to cost and layout simplicity. | Select when 10-MHz bandwidth and independent shutdown are unnecessary; avoid if rail-to-rail output swing below 100 mV is required. |
| TLV9002IDSGR | Higher quiescent current (600 µA/ch), lower ESD rating (2-kV HBM), same 10-MHz GBW but higher offset (±1.6 mV). | Better suited for general-purpose industrial IO modules where absolute precision is less critical than drive strength. | Choose for higher output current capability (50 mA short-circuit) and wider temp range (–40°C to +125°C); verify offset drift impact in precision references. |
Compared with OPA2316SIDGS, OPA2313IDGKR trades bandwidth and noise performance for lower cost and simpler layout, while TLV9002IDSGR offers stronger output drive at the expense of precision and ESD robustness - making OPA2316SIDGS optimal for battery-constrained, noise-sensitive, and safety-critical dual-channel signal chains.

FAQ
What is the maximum supply voltage for OPA2316SIDGS?
The OPA2316SIDGS supports a total supply voltage range of 1.8 V to 5.5 V. This includes single-supply operation (e.g., V+ = 3.3 V, V– = GND) and split-supply configurations (e.g., V+ = +2.75 V, V– = –2.75 V). Operation beyond 5.5 V risks permanent damage per absolute maximum ratings.
Does OPA2316SIDGS support rail-to-rail input and output simultaneously?
Yes, the OPA2316SIDGS features true rail-to-rail input and output (RRIO) operation. Its CMOS input stage accepts common-mode voltages from (V–) – 0.2 V to (V+) + 0.2 V, and its output swings within 15 mV of either rail at 1.8 V supply - enabling full utilization of low-voltage ADC reference ranges.
How does the shutdown function operate on OPA2316SIDGS?
OPA2316SIDGS provides independent shutdown control via SHDN_A and SHDN_B pins. Driving either pin low disables its respective amplifier output (high-Z state) with tOFF = 5 µs; driving high enables it with tON = 13 µs (full shutdown) or 10 µs (partial). Full shutdown draws only 0.01 µA per device.
What is the typical input offset voltage drift of OPA2316SIDGS over temperature?
The OPA2316SIDGS exhibits a typical input offset voltage drift of ±2 µV/°C over the full –40°C to +125°C operating range. This low drift ensures minimal calibration drift in precision applications such as medical sensor front-ends and battery voltage monitors where long-term accuracy is critical.
Is OPA2316SIDGS compatible with standard MSOP-10 PCB footprints?
Yes, OPA2316SIDGS uses the industry-standard 10-pin MSOP (DGS) package with 0.5-mm pitch and 3.00 mm × 3.00 mm body size. Its pinout matches JEDEC MO-187AA, and the exposed thermal pad on the underside is designed for connection to V– - ensuring compatibility with existing MSOP-10 layout templates and reflow profiles.
