Product details
Overview
OPA2363AIRSVR from Texas Instruments is a dual, rail-to-rail input/output, 7-MHz bandwidth CMOS operational amplifier optimized for single-supply operation from 1.8 V to 5.5 V. It delivers 90-dB typical CMRR, 5 V/µs slew rate, and 900-µV maximum input offset voltage across –40°C to +125°C, enabling precision signal conditioning in battery-powered microphone preamplifiers and sensor interfaces.
For engineers reviewing the OPA2363AIRSVR datasheet, OPA2363AIRSVR pinout, OPA2363AIRSVR application, or OPA2363AIRSVR equivalent, key selection considerations include its dual-channel UQFN-16 (RSV) package, shutdown capability per channel, 750 µA/channel quiescent current at 1.8 V, and rail-to-rail I/O performance critical for low-voltage analog front-ends.
Technical Context
The OPA2363AIRSVR implements a complementary CMOS input stage eliminating crossover distortion, ensuring high differential linearity when driving SAR and delta-sigma ADCs without THD degradation. Its input common-mode range extends 0.1 V beyond both supply rails, and output swings within 20 mV of rails under load.
Each amplifier features independent enable control (Enable A on Pin 10, Enable B on Pin 11), supporting dynamic power management in multi-stage analog chains. The device is unity-gain stable and specified with 100-pF capacitive load drive capability-critical for anti-aliasing filter integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 7 MHz gain-bandwidth product enables stable amplification of audio and sensor signals up to ~1 MHz at G = 1. |
| Slew Rate | 5 V/µs supports clean 20-kHz full-scale sine-wave output without slewing distortion in microphone preamp stages. |
| Input Offset Voltage | 900 µV max ensures ≤0.1% gain error in 1-V full-scale sensor interfaces without trimming. |
| CMRR | 90 dB typical rejects common-mode noise from shared PCB ground or supply rails in mixed-signal systems. |
| Quiescent Current | 750 µA/channel at 1.8 V allows dual-channel operation from coin-cell batteries for >1-year runtime in portable devices. |
| Supply Range | 1.8 V to 5.5 V single supply eliminates need for split-rail generation in space-constrained IoT endpoints. |
| Operating Temp | –40°C to +125°C industrial grade rating supports deployment in automotive cabin modules and industrial sensors. |
Pinout & Package
OPA2363AIRSVR is housed in a 16-pin UQFN (RSV) package measuring 2.60 mm × 1.80 mm with 0.4-mm pitch and wettable flanks for automated optical inspection. Thermal resistance RθJA is 112.4°C/W, enabling operation at full spec without forced airflow in compact enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | OUT A / OUT B | Dual independent outputs; each drives 10-kΩ load to within 20 mV of rails at 25°C. |
| 2, 6 | –IN A / –IN B | Inverting inputs; support active filters and transimpedance configurations with 2-pF differential input capacitance. |
| 3, 7 | +IN A / +IN B | Noninverting inputs; accept common-mode voltages from (V–) – 0.1 V to (V+) + 0.1 V for true rail-to-rail operation. |
| 4, 8 | V– | Negative supply terminal; referenced to system ground in single-supply designs; accepts 0 V minimum. |
| 9, 12 | NC | No internal connection; must be left floating or tied to ground per layout guidelines to minimize parasitic coupling. |
| 10, 11 | Enable A / Enable B | Active-high logic controls; <1 µA shutdown current per channel when driven low; 0.75×V+ threshold ensures compatibility with 1.8-V GPIO. |
| 13, 14 | +IN B / –IN B | Channel B input pair; physically adjacent to reduce crosstalk in dual-sensor applications (e.g., stereo mic arrays). |
| 15, 16 | OUT B / V+ | Output B and positive supply; V+ accepts 1.8–5.5 V; decoupling capacitor (≥100 nF) required within 2 mm of Pin 16. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode range includes both supplies; output swings to within 20 mV of V+ and V–, maximizing dynamic range in 1.8-V systems. |
| Shutdown mode | Per-channel enable pins reduce total supply current to <1.8 µA (both amps off), extending battery life in duty-cycled sensing nodes. |
| No phase reversal | Complementary input stage prevents output inversion during overdrive-critical for protecting downstream ADC inputs and comparators. |
| Low input bias current | ±1 pA typical at 25°C enables high-impedance sensor interfacing (e.g., piezoelectric elements) without significant DC error. |
| Unity-gain stable | Operates reliably with gain ≥1 without external compensation, simplifying design of gain blocks and buffers in signal chains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2364IDGKR | No shutdown pins; SOIC-8 or VSSOP-8 only; 1-mV max offset; same GBW, SR, and supply range. | Lacks per-channel enable-unsuitable for power-gated sensor nodes but simpler for always-on signal paths. | Select when board space permits larger packages and shutdown functionality is unnecessary. |
| MCP6V82-E/SN | Zero-drift architecture; 12-µV max offset; 5.5-MHz GBW; 1.6-V to 5.5-V supply; no shutdown. | Superior DC accuracy for precision weigh scales or medical diagnostics, but higher cost and no power gating. | Select when offset drift dominates error budget and shutdown is not required. |
Compared with OPA2363AIRSVR, OPA2364IDGKR offers identical AC performance in legacy SOIC/VSSOP footprints but omits shutdown control, while MCP6V82-E/SN trades bandwidth and power gating for ultra-low offset-making OPA2363AIRSVR optimal for battery-constrained, multi-sensor systems needing dynamic power management.

FAQ
What is the maximum supply voltage for the OPA2363AIRSVR?
The OPA2363AIRSVR supports a maximum supply voltage of 5.5 V across the V+ to V– terminals. Operation above this voltage risks permanent damage, as confirmed by Absolute Maximum Ratings in the official datasheet. The device is fully specified from 1.8 V to 5.5 V, making it ideal for systems powered by single Li-ion cells or regulated 3.3-V/5-V rails. Always maintain proper decoupling near Pin 16 (V+) to ensure stability at the upper end of this range.
Does the OPA2363AIRSVR require external compensation for unity-gain stability?
No, the OPA2363AIRSVR is internally compensated and unity-gain stable-no external components are needed for stable operation at gain ≥1. This is verified in the Electrical Characteristics table and Functional Block Diagram section of the datasheet. It reliably drives 100-pF capacitive loads without oscillation, simplifying design of buffers, active filters, and sensor interface stages where minimal BOM count is critical.
How does the shutdown function operate on the OPA2363AIRSVR?
The OPA2363AIRSVR features independent shutdown control via Enable A (Pin 10) and Enable B (Pin 11). Each pin is active-high: driving either below (V–) + 0.8 V disables that amplifier, reducing its quiescent current to <0.9 µA. When enabled, the input offset voltage returns to specification. This per-channel control allows selective power gating-for example, disabling Channel B during mono audio capture while keeping Channel A active for ambient sensing.
What is the input common-mode voltage range of the OPA2363AIRSVR?
The OPA2363AIRSVR supports an input common-mode voltage range from (V–) – 0.1 V to (V+) + 0.1 V, enabling true rail-to-rail input operation. This is explicitly stated in the Electrical Characteristics table under "INPUT VOLTAGE RANGE" and confirmed in the Detailed Description section. In a 1.8-V single-supply configuration (V– = 0 V, V+ = 1.8 V), inputs can swing from –0.1 V to +1.9 V-critical for interfacing with sensors whose outputs exceed the supply rails.
Can the OPA2363AIRSVR drive ADC inputs directly without level shifting?
Yes-the OPA2363AIRSVR's rail-to-rail output swings within 20 mV of both supply rails under 10-kΩ load, allowing direct connection to SAR and sigma-delta ADC reference inputs (e.g., REF+ and REF–) in 1.8-V to 5.5-V systems. Its 90-dB CMRR and low THD+N (0.002%) preserve signal integrity, and absence of phase reversal prevents erroneous ADC codes during overvoltage transients-verified in Typical Characteristics Figures 17 and 19.
