Product details
Overview
OPA2316SIDGSR from Texas Instruments is a dual-channel, rail-to-rail input/output, low-noise 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 operates across –40°C to +125°C - enabling precision signal conditioning in space-constrained, battery-powered medical sensors and portable instrumentation.
For engineers reviewing the OPA2316SIDGSR datasheet, OPA2316SIDGSR pinout, OPA2316SIDGSR application, or OPA2316SIDGSR equivalent, this page provides verified package mapping (MSOP-10), validated dual-channel shutdown timing (tON = 13 µs, tOFF = 5 µs), confirmed rail-to-rail output swing (≤30 mV from rails at 5.5 V), and real-world EMI filtering performance backed by TI's integrated RFI-EMI rejection filter.
Technical Context
The OPA2316SIDGSR implements a fully differential input stage with p-channel and n-channel input transistors, enabling true rail-to-rail common-mode input range down to (V–) – 0.2 V and up to (V+) + 0.2 V at 5.5 V supply. Its internal compensation ensures unity-gain stability with no external components required.
Each channel features independent shutdown control (SHDN_A/SHDN_B), with full-device quiescent current dropping to ≤1 µA when both channels are disabled. The device maintains 60° phase margin and 6 V/µs slew rate under G = +1 conditions, supporting fast-settling (1.66 µs to 0.01%) closed-loop configurations for active filters and audio line drivers.

Pinout & Package
OPA2316SIDGSR is housed in a 10-pin MSOP (DGS) package measuring 3.0 mm × 3.0 mm × 1.0 mm, with exposed thermal pad connected to V– for enhanced thermal dissipation (RθJB = 110.7°C/W). Pin 1 is marked via dot; pin numbering follows standard MSOP convention (counterclockwise from top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 10 kΩ with rail-to-rail swing and 6 V/µs slew rate. |
| 2 | –IN A | Inverting input for Channel A - accepts signals within (V–) – 0.2 V to (V+) + 0.2 V at 5.5 V supply. |
| 3 | +IN A | Noninverting input for Channel A - high-impedance (1016 Ω || pF) node for sensor or reference connections. |
| 4 | V– | Negative supply or ground - also connects to exposed thermal pad; must be low-impedance for stability and thermal performance. |
| 5 | SHDN A | Channel A shutdown control - logic high (≥ V+ – 0.5 V) enables; logic low (≤ V– + 0.2 V) disables with 5 µs disable time. |
| 6 | SHDN B | Channel B shutdown control - independent of SHDN A; allows asymmetric power management in dual-signal paths. |
| 7 | +IN B | Noninverting input for Channel B - electrically identical to +IN A; supports differential or independent signal routing. |
| 8 | –IN B | Inverting input for Channel B - matched bias current (±5 pA typ) and offset voltage to Channel A for ratio-metric accuracy. |
| 9 | OUT B | Amplifier B output - fully independent channel with same AC/DC specs as OUT A; enables dual-path signal processing. |
| 10 | V+ | Positive supply - accepts 1.8 V to 5.5 V; internal regulation ensures consistent 400-µA IQ across full voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated RFI-EMI Filter | Rejects >30 dB of RF interference above 100 MHz - eliminates need for external ferrite beads in noisy environments (e.g., motor drives, wireless modules). |
| No Phase Reversal in Overdrive | Prevents output latch-up when inputs exceed supply rails - simplifies design of overvoltage-tolerant front-ends without clamping diodes. |
| High ESD Protection | ±4-kV HBM - withstands handling and board assembly without additional protection circuitry. |
| Low Input Bias Current | ±5 pA (typ) - enables use with MΩ-level source impedances (e.g., pH electrodes, photodiode transimpedance stages). |
| Robust Power-On Behavior | 200-µs power-on time with monotonic output - avoids glitches during brown-out recovery in battery-powered systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-power, rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2313IDGSR | Lower bandwidth (1 MHz), higher noise (25 nV/√Hz), no shutdown pins, same MSOP-8 package. | Suitable only for DC/low-frequency sensor buffering where speed and noise are non-critical. | Select when cost sensitivity outweighs bandwidth/noise requirements and shutdown is unnecessary. |
| TLV9062IDGSR | Higher bandwidth (10 MHz), lower noise (10.8 nV/√Hz), 500-µA/ch IQ, no integrated RFI filter, SOIC-8/MSOP-8 packages only. | Lacks dedicated shutdown control and EMI filtering - requires external layout mitigation in noisy environments. | Choose when maximum speed/noise performance is prioritized and PCB layout can accommodate external filtering. |
Compared with OPA2316SIDGSR, OPA2313IDGSR trades bandwidth and noise for lower cost and simpler control, while TLV9062IDGSR offers marginal noise improvement but sacrifices integrated EMI rejection and dual-channel shutdown - making OPA2316SIDGSR optimal for compact, battery-powered, noise-sensitive dual-signal systems requiring guaranteed robustness.

FAQ
What is the maximum supply voltage for OPA2316SIDGSR?
The OPA2316SIDGSR supports a total supply voltage range of 1.8 V to 5.5 V. This includes single-supply operation (e.g., V+ = 5.5 V, V– = 0 V) and split-supply configurations (e.g., V+ = +2.75 V, V– = –2.75 V). Absolute maximum ratings specify 7 V across V+ and V–, but operation beyond 5.5 V is not characterized or guaranteed. All electrical specifications in the datasheet are validated within the 1.8 V–5.5 V range.
Does OPA2316SIDGSR support true rail-to-rail input and output?
Yes, OPA2316SIDGSR provides true rail-to-rail input and output operation. Its input common-mode range extends from (V–) – 0.2 V to (V+) + 0.2 V at 5.5 V supply, and its output swings within 30 mV of each rail under 10-kΩ load. This capability is maintained across the full –40°C to +125°C temperature range and enables direct interfacing with ADCs and DACs operating at the same supply rails - eliminating level-shifting circuitry in OPA2316SIDGSR-based designs.
How does the shutdown feature work on OPA2316SIDGSR?
OPA2316SIDGSR has two independent shutdown pins: SHDN_A (Pin 5) and SHDN_B (Pin 6). Driving either pin low (≤ V– + 0.2 V) disables its respective amplifier channel, reducing that channel's quiescent current to ≤1 µA. When both pins are low, total device IQ drops to ≤1 µA. Enable time is 13 µs (full shutdown) and 10 µs (partial shutdown); disable time is 5 µs. This allows granular power control in dual-signal-path systems without affecting the active channel's performance.
Is OPA2316SIDGSR unity-gain stable?
Yes, OPA2316SIDGSR is internally compensated for unity-gain stability. It achieves 60° phase margin and remains stable with closed-loop gains ≥ +1, including voltage followers and inverting configurations with G = –1. No external compensation components are required. This is confirmed across all supply voltages (1.8 V–5.5 V), temperatures (–40°C to +125°C), and load conditions (up to 100 pF capacitive load), making OPA2316SIDGSR suitable for general-purpose gain blocks without stability analysis overhead.
What packaging and thermal characteristics apply to OPA2316SIDGSR?
OPA2316SIDGSR uses a 10-pin MSOP (DGS) package with 3.0 mm × 3.0 mm body size and an exposed thermal pad connected to V–. Its junction-to-board thermal resistance (RθJB) is 110.7°C/W, and ψJB is 109.1°C/W - indicating strong thermal coupling to the PCB. The exposed pad must be soldered to a thermal copper pour tied to V– for optimal performance. Maximum junction temperature is 150°C; derating is required above 125°C ambient per the thermal metrics table in the datasheet.
