Product details
Overview
OPA2363IDGSR from Texas Instruments is a dual-channel, rail-to-rail input/output CMOS operational amplifier optimized for 1.8-V to 5.5-V single-supply operation. It delivers 7-MHz gain-bandwidth, 5-V/µs slew rate, 90-dB typical CMRR, and 750-µA maximum quiescent current per channel - enabling precision signal conditioning in battery-powered microphone preamplifiers and sensor interfaces.
For engineers reviewing the OPA2363IDGSR datasheet, OPA2363IDGSR pinout, OPA2363IDGSR application, or OPA2363IDGSR equivalent, key selection criteria include its dual-channel VSSOP-10 package, shutdown-enabled architecture (Enable A/B pins), rail-to-rail I/O swing within 10 mV of rails, and guaranteed operation from –40°C to +125°C in industrial and automotive sensing systems.
Technical Context
The OPA2363IDGSR implements a complementary CMOS input stage that eliminates crossover distortion, ensuring high common-mode rejection (90 dB typ.) across the full input range - critical for driving SAR ADCs without THD degradation. Its unity-gain stable architecture supports active filter and transimpedance configurations with minimal phase margin compromise.
Each channel features independent enable control (pins 5 and 6 in DGS package), allowing dynamic power management: shutdown current drops below 1 µA per amplifier while preserving fast turn-on (20 µs) and turn-off (1 µs) timing. Input bias current remains ultra-low (±1 pA typ. at 25°C), supporting high-impedance sensor interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.8 V to 5.5 V single supply - enables direct interface with Li-ion, coin-cell, and 3.3-V logic systems without level-shifting. |
| Gain-Bandwidth Product | 7 MHz - supports stable closed-loop gain up to 10× at audio bandwidths (20 kHz) with <0.1% settling in 1 µs. |
| Input Offset Voltage | 900 µV max (I-grade) - ensures ≤0.5% error in 1-V full-scale sensor amplification without trimming. |
| Slew Rate | 5 V/µs - handles 2-Vpp, 20-kHz sinusoids with <0.002% THD+N, suitable for electret microphone preamp stages. |
| Quiescent Current | 750 µA/channel max - allows dual-channel operation on <1.5 mA total, extending battery life in portable audio devices. |
| CMRR | 90 dB typical - rejects power-supply ripple and EMI coupling in noisy industrial environments without degrading differential linearity. |
| Output Swing | Within 10 mV of rails (RL = 10 kΩ) - maximizes dynamic range when digitizing signals into 12-bit+ ADCs. |
Pinout & Package
OPA2363IDGSR is housed in a 10-pin VSSOP (DGS) package measuring 3.00 mm × 3.00 mm, optimized for space-constrained PCB layouts in wearables and IoT edge nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT A | Amplifier A output - drives downstream ADC input or filter network; rail-to-rail swing supports full-scale utilization. |
| 2 | –IN A | Inverting input, channel A - used in transimpedance or inverting gain configurations; low input bias enables >1-MΩ feedback networks. |
| 3 | +IN A | Noninverting input, channel A - accepts high-impedance sensor signals (e.g., electret mic bias node); rail-to-rail common-mode range includes ground. |
| 4 | V– | Negative supply - connects directly to system ground in single-supply operation; no negative rail required. |
| 5 | Enable A | Logic-controlled shutdown for channel A - TTL-compatible input; pulls channel A quiescent current to <1 µA when low. |
| 6 | Enable B | Logic-controlled shutdown for channel B - independent control enables asymmetric power gating in multi-sensor systems. |
| 7 | +IN B | Noninverting input, channel B - identical functionality to pin 3; supports dual-sensor or differential pair architectures. |
| 8 | –IN B | Inverting input, channel B - matches pin 2 electrical behavior; enables matched dual-channel filtering or instrumentation topologies. |
| 9 | VOUT B | Amplifier B output - electrically isolated from VOUT A; supports independent signal paths without crosstalk (130 dB @ 1 kHz). |
| 10 | V+ | Positive supply - accepts 1.8–5.5 V; internal charge pump enables rail-to-rail output even at 1.8-V operation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode range extends 0.1 V beyond both rails; output swings to within 10 mV of V+ and V– - preserves full ADC input range in low-voltage systems. |
| Shutdown mode | Independent Enable A/B pins reduce each channel's supply current to <1 µA - cuts total idle power by >99.9% versus active mode. |
| No phase reversal | Complementary input stage prevents output inversion during overdrive - eliminates latch-up risk in sensor fault conditions. |
| Low input bias current | ±1 pA typical at 25°C - enables use with high-value feedback resistors (>1 MΩ) without significant offset drift or noise penalty. |
| Industrial temperature range | Specified from –40°C to +125°C - qualified for under-hood automotive, motor control feedback, and industrial process monitoring. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2364IDGKR | No shutdown pins; 8-pin VSSOP package; same GBW, slew rate, and quiescent current. | Lacks independent channel enable - unsuitable for dynamic power-gating architectures requiring per-channel sleep control. | Select when board space permits larger 8-pin VSSOP and shutdown functionality is unnecessary. |
| MCP6022-I/SN | Lower GBW (10 MHz), higher quiescent current (1 mA/channel), no shutdown, SOIC-8 package. | Higher power consumption limits battery life; lacks rail-to-rail input - cannot accept signals near ground in single-supply designs. | Choose only if legacy SOIC footprint compatibility is mandatory and 1.8-V operation is not required. |
Compared with OPA2364IDGKR and MCP6022-I/SN, the OPA2363IDGSR uniquely combines dual-channel shutdown, 10-pin VSSOP compactness, and guaranteed 1.8-V operation - making it optimal for space- and power-constrained dual-sensor systems requiring independent channel control.

FAQ
What is the minimum supply voltage for reliable operation of the OPA2363IDGSR?
The OPA2363IDGSR is fully specified from 1.8 V to 5.5 V single supply. At 1.8 V, it maintains 7-MHz gain-bandwidth, 5-V/µs slew rate, and rail-to-rail output swing - enabling direct integration with energy-harvesting PMUs and coin-cell systems without voltage boosting.
Does the OPA2363IDGSR require external compensation for unity-gain stability?
No. The OPA2363IDGSR is internally compensated and unity-gain stable across its full operating range. It drives capacitive loads up to 100 pF without oscillation, supporting direct connection to ADC inputs and RC filters without added phase-margin compensation networks.
How does the shutdown function operate on the OPA2363IDGSR?
The OPA2363IDGSR has two independent shutdown pins: Enable A (pin 5) and Enable B (pin 6). Driving either pin low disables its respective amplifier, reducing quiescent current to <1 µA. Both channels remain active when pins are pulled high to V+ or ≥0.75×V+.
Can the OPA2363IDGSR drive a 10-kΩ load rail-to-rail at 5 V supply?
Yes. With RL = 10 kΩ and VS = 5 V, the OPA2363IDGSR delivers output swing within 10 mV of both rails at 25°C, and within 20 mV over the full –40°C to +125°C range - ensuring full utilization of 12-bit+ ADC input ranges in precision data acquisition systems.
What is the input bias current specification for the OPA2363IDGSR over temperature?
The OPA2363IDGSR specifies ±1 pA typical input bias current at 25°C, with values remaining below ±10 pA across –40°C to +125°C. This ultra-low bias enables high-impedance sensor interfaces (e.g., pH electrodes, photodiodes) without significant offset drift or Johnson noise contribution.
