Product details
Overview
OPA363AIDBVTG4 from Texas Instruments is a single-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 500-µV maximum input offset voltage - enabling precision signal conditioning in battery-powered microphone preamplifiers and data acquisition systems.
For engineers reviewing the OPA363AIDBVTG4 datasheet, OPA363AIDBVTG4 pinout, OPA363AIDBVTG4 application, or OPA363AIDBVTG4 equivalent, key selection criteria include its shutdown capability (sub-1-µA quiescent current), 10-mV rail-to-rail output swing at 25°C, and guaranteed operation from –40°C to +125°C in the 6-pin SOT-23 package.
Technical Context
The OPA363AIDBVTG4 uses a complementary input stage architecture that eliminates crossover distortion, ensuring monotonic common-mode response and preserving differential linearity when driving SAR or delta-sigma ADCs. Its rail-to-rail input range extends 100 mV beyond both supply rails, and output swings within 10 mV of each rail under 10-kΩ load.
It integrates an active enable/shutdown control pin (pin 5 in DBV package) that reduces quiescent current to ≤0.9 µA per channel while maintaining fast turnon (20 µs) and turnoff (1 µs) timing. The device is unity-gain stable and specified with 100-pF capacitive load drive capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V single supply - supports direct interfacing with Li-ion, coin-cell, and low-voltage microcontrollers. |
| Gain-Bandwidth Product | 7 MHz - enables stable amplification of audio-band signals up to ~100 kHz at G = 10 without phase margin loss. |
| Slew Rate | 5 V/µs - ensures <1.5 µs settling to 0.01% for 4-V step inputs, critical for fast data acquisition front-ends. |
| Input Offset Voltage | ≤500 µV (max) - minimizes DC error in precision sensor interfaces like electret microphone biasing networks. |
| CMRR | 90 dB (typical) - rejects power-supply noise and common-mode interference in noisy industrial environments. |
| Quiescent Current | 750 µA/channel (max) - enables multi-day battery life in always-on portable audio sensors. |
| Shutdown Current | ≤0.9 µA/channel - allows ultra-low-power sleep modes in wake-on-sound applications. |
Pinout & Package
OPA363AIDBVTG4 is housed in a 6-pin SOT-23 (DBV) package measuring 2.60 mm × 1.60 mm, with exposed pad for thermal enhancement. Pin 1 is marked via laser scribe or dot; orientation follows JEDEC MO-178 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Output | Amplified analog output node; rail-to-rail swing (within 10 mV of V+ or V–) into 10-kΩ load. |

| 3 (+IN) | Noninverting Input | High-impedance (≥1013 Ω) input accepting common-mode voltages from (V–) – 0.1 V to (V+) + 0.1 V. |
| 4 (–IN) | Inverting Input | Differential input node; used with feedback network to set closed-loop gain and bandwidth. |
| 5 (EN) | Enable/Shut Down | Logic-controlled input: high (>0.75×V+) enables operation; low ( |
| 6 (V+) | Positive Supply | Highest potential supply connection; accepts 1.8–5.5 V with PSRR ≥80 dB across 10 Hz–100 kHz. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode range includes both supply rails; output swings to within 10 mV of V+ and V– - eliminates level-shifting circuitry in 1.8-V systems. |
| No phase reversal | Complementary input stage prevents output inversion during input overdrive - ensures safe interface with downstream ADCs and comparators. |
| Low-noise performance | 17 nV/√Hz input voltage noise density at 10 kHz - preserves SNR in microphone preamp stages with >60-dB dynamic range. |
| Unity-gain stability | Stable with gain ≥1 and 100-pF capacitive load - simplifies layout in space-constrained PCBs without external compensation. |
| Extended temperature range | Specified from –40°C to +125°C - qualified for automotive cabin modules, industrial process controllers, and outdoor IoT sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA364AIDBVR | 5-pin SOT-23; no shutdown pin; identical GBW, slew rate, and offset specs. | Lacks enable control - unsuitable for duty-cycled or ultra-low-power sleep modes. | Select when shutdown functionality is unnecessary and board space is constrained by pin count. |
| MCP6001T-E/OT | 1-MHz GBW, 0.6-V/µs slew rate, 1.5-mV max offset; 6-pin SOT-23, same footprint. | Lower bandwidth and higher offset limit use in audio or precision DC-coupled paths. | Choose for cost-sensitive, low-speed applications where 7-MHz bandwidth is not required. |
Compared with OPA363AIDBVTG4, OPA364AIDBVR offers identical analog performance but omits shutdown control - trading power flexibility for minimal footprint. MCP6001T-E/OT provides pin-compatible packaging at lower speed and accuracy, serving as a budget-tier alternative for non-critical signal chains.

FAQ
What is the operating temperature range for OPA363AIDBVTG4?
The OPA363AIDBVTG4 is fully specified from –40°C to +125°C ambient temperature. This extended industrial range ensures reliable operation in automotive cabin modules, industrial PLCs, and outdoor IoT sensors where thermal stress is significant. All key parameters - including offset voltage, CMRR, and quiescent current - are guaranteed across this full span.
Does OPA363AIDBVTG4 require external compensation for stability?
No, OPA363AIDBVTG4 is unity-gain stable and does not require external compensation components. It maintains ≥45° phase margin with capacitive loads up to 100 pF and closed-loop gains ≥1. This simplifies design in compact layouts where stray capacitance is difficult to control, such as in microphone preamp PCB traces or sensor module flex circuits.
How does the enable pin (EN) on OPA363AIDBVTG4 function?
The EN pin (pin 5) controls amplifier state: logic high (>0.75×V+) enables normal operation with 750-µA max quiescent current; logic low (
Can OPA363AIDBVTG4 drive ADC inputs directly?
Yes, OPA363AIDBVTG4 is optimized for direct ADC driving. Its rail-to-rail output swing, 90-dB CMRR, absence of phase reversal, and 0.01% settling in 1.5 µs ensure accurate sampling without degradation of differential linearity or THD. It maintains performance with 10-kΩ ADC input impedance and 100-pF sampling capacitor loads.
What is the maximum capacitive load OPA363AIDBVTG4 can drive reliably?
OPA363AIDBVTG4 is characterized to drive up to 100 pF capacitive load while maintaining stability and specified settling time. Driving larger loads (e.g., >200 pF) may cause peaking or ringing; in such cases, an isolation resistor (10–50 Ω) between OPA363AIDBVTG4 output and the load restores stability without degrading DC accuracy.
