Product details
Overview
OPA363IDBVTG4 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, and 90-dB typical CMRR, with shutdown capability (<1 µA quiescent current per channel) - enabling precision signal conditioning in battery-powered microphone preamplifiers and sensor interfaces.
For engineers reviewing the OPA363IDBVTG4 datasheet, OPA363IDBVTG4 pinout, OPA363IDBVTG4 application, or OPA363IDBVTG4 equivalent, key selection criteria include its 500-µV max input offset voltage, ±1-pA input bias current, 17-nV/√Hz input voltage noise density at 10 kHz, and guaranteed operation from –40°C to +125°C in the 6-pin SOT-23 package.
Technical Context
The OPA363IDBVTG4 employs a complementary CMOS input stage that eliminates crossover distortion, ensuring high common-mode rejection (90 dB typ.) across the full input range - from (V–) – 0.1 V to (V+) + 0.1 V - without phase reversal. Its rail-to-rail output swings within 10 mV of both supply rails under 10-kΩ load.
Integrated shutdown logic (active-high Enable pin) reduces quiescent current to <1 µA per channel while preserving fast turnon (20 µs) and turnoff (1 µs) times. The device is unity-gain stable and specified for capacitive loads up to 100 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.8 V to 5.5 V single supply - supports direct interface with Li-ion, coin-cell, and low-voltage MCU I/O domains. |
| Gain-Bandwidth Product | 7 MHz - enables stable amplification of audio-band signals (e.g., electret mic outputs) with minimal phase lag. |
| Input Offset Voltage | ≤500 µV (max) - ensures DC accuracy in precision sensor front-ends without trimming. |
| Input Bias Current | ±1 pA (typ.) - minimizes error in high-impedance source applications like piezoelectric or electret microphone bias networks. |
| Slew Rate | 5 V/µs - supports clean 20-kHz full-scale signal reproduction with <0.002% THD+N. |
| CMRR | 90 dB (typ.) - rejects power-supply ripple and common-mode interference in noisy embedded environments. |
| Shutdown Current | <1 µA per channel - extends battery life in intermittent-sensing systems (e.g., voice-activated wake-up). |
Pinout & Package
OPA363IDBVTG4 is housed in a 6-pin SOT-23 (DBV) package measuring 2.60 mm × 1.60 mm, optimized for space-constrained portable electronics. Thermal resistance RθJA is 211.4°C/W, requiring minimal PCB copper for industrial-temperature operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT | Output | Amplified analog signal node; rail-to-rail swing (within 10 mV of V+ or V–) into 10-kΩ load. |
| 2 - V– | Negative Supply | Lowest potential supply rail; referenced to ground in single-supply configurations. |
| 3 - +IN | Noninverting Input | High-impedance (≥1013 Ω), low-bias-current node for reference or sensor signal routing. |
| 4 - –IN | Inverting Input | Feedback node; accepts resistive or capacitive network connections for gain/compensation control. |
| 5 - Enable | Shutdown Control | Active-high logic input; drives amplifier into ultra-low-power state when pulled low or left floating (internal pull-down). |
| 6 - V+ | Positive Supply | Highest potential supply rail; supports 1.8–5.5 V operation with PSRR ≥80 dB over 10 Hz–100 kHz. |
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– - maximizes dynamic range in low-voltage systems. |
| No Phase Reversal | Complementary input stage prevents output inversion during input overdrive - critical for reliable A/D converter driving. |
| Ultra-Low Input Bias Current | ±1 pA typical - enables use with high-impedance sources (e.g., 100-kΩ microphone bias resistors) without significant DC error. |
| Low 1/f Noise | 10 µVPP (0.1–10 Hz) - preserves signal integrity in DC-coupled sensor amplification and precision instrumentation. |
| Industrial Temp Range | Specified from –40°C to +125°C - suitable for automotive cabin modules, industrial IoT nodes, and harsh-environment monitoring. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA364IDBVR | No shutdown pin; 5-pin SOT-23; identical bandwidth, noise, and offset specs but lacks enable functionality. | Used where continuous operation is required and board space is constrained - eliminates need for enable logic routing. | Select OPA364IDBVR when shutdown is unnecessary and lowest footprint is critical. |
| MCP6001T-E/OT | Lower bandwidth (1 MHz), higher offset (1.5 mV max), no shutdown; Microchip's 5-pin SOT-23 op amp with similar 1.8-V operation. | Cost-sensitive consumer applications where audio fidelity and precision are secondary to BOM cost. | Choose MCP6001T-E/OT only for non-critical signal paths where 7-MHz GBW and sub-mV offset are not required. |
Compared with OPA364IDBVR, OPA363IDBVTG4 adds shutdown control at the cost of one extra pin; versus MCP6001T-E/OT, it delivers 7× higher bandwidth, 3× lower offset, and guaranteed industrial-temperature performance - making it the preferred choice for precision, low-power, and thermally demanding designs.

FAQ
What is the maximum supply voltage for OPA363IDBVTG4?
The OPA363IDBVTG4 supports a maximum supply voltage of 5.5 V across the V+ to V– terminals. Absolute maximum ratings specify that exceeding this voltage - even momentarily - may cause permanent damage. Operation is fully characterized from 1.8 V to 5.5 V, with optimal performance observed at 3.3 V and 5 V nominal supplies. Always observe the recommended operating conditions in the official Texas Instruments datasheet for OPA363IDBVTG4.
Does OPA363IDBVTG4 require external compensation for unity-gain stability?
No, the OPA363IDBVTG4 is internally compensated and unity-gain stable. It drives capacitive loads up to 100 pF without oscillation, as verified in the datasheet's typical characteristics (Figure 19 and Figure 20). For loads exceeding 100 pF, a small series resistor (e.g., 10–50 Ω) at the output is recommended to maintain phase margin - a design practice confirmed in TI's application notes for OPA363IDBVTG4.
How does the Enable pin function on OPA363IDBVTG4?
The Enable pin (Pin 5) on OPA363IDBVTG4 is active-high: driving it to ≥0.75 × V+ enables normal operation; pulling it ≤(V–) + 0.8 V places the amplifier in shutdown mode, reducing quiescent current to <1 µA per channel. An internal pull-down ensures safe default-off behavior if left unconnected. Turnon time is 20 µs and turnoff time is 1 µs - parameters explicitly tested and guaranteed for OPA363IDBVTG4.
Can OPA363IDBVTG4 drive an ADC input directly?
Yes, OPA363IDBVTG4 is expressly designed to drive SAR and delta-sigma ADC inputs. Its rail-to-rail output swing (within 10 mV of rails), low THD+N (0.002%), and absence of phase reversal allow clean, distortion-free sampling - especially critical when driving mid-supply-referenced ADCs. The 7-MHz bandwidth and 5-V/µs slew rate support accurate settling of full-scale steps, as validated in the OPA363IDBVTG4 datasheet's settling time specifications.
Is OPA363IDBVTG4 suitable for automotive applications?
OPA363IDBVTG4 is qualified for operation from –40°C to +125°C and meets JEDEC JESD22-A108 reliability standards, making it suitable for under-hood and cabin automotive applications such as HVAC sensor interfaces or infotainment microphone preamps. However, it is not AEC-Q200 qualified; for safety-critical or ASIL-rated systems, designers must perform full qualification testing per their OEM requirements - a requirement explicitly noted in TI's production data notice for OPA363IDBVTG4.
