Product details
Overview
OPA374AIDBVTG4 from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-power, high-bandwidth signal conditioning in battery-powered and portable systems. It delivers 6.5 MHz gain-bandwidth, 5 V/µs slew rate, 585 µA quiescent current, and operates from 2.3 V to 5.5 V supply - enabling precision amplification in space-constrained, single-supply applications such as sensor front-ends and A/D converter drivers.
For engineers reviewing the OPA374AIDBVTG4 datasheet, OPA374AIDBVTG4 pinout, OPA374AIDBVTG4 application, or OPA374AIDBVTG4 equivalent, key selection criteria include its 5-mV max input offset voltage, 10-pA max input bias current, rail-to-rail I/O swing within 25 mV of rails, operation up to 125°C, and compatibility with 5-pin SOT-23 packaging for ultra-compact PCB layouts.
Technical Context
The OPA374AIDBVTG4 uses a complementary CMOS input stage enabling rail-to-rail input common-mode range from (V−) −0.2 V to (V+) + 0.2 V - including 200 mV beyond both supply rails. Its class AB output stage supports rail-to-rail output swing, delivering 18 mV typical voltage headroom at light loads (100 kΩ) and 100 mV at moderate loads (5 kΩ).
No shutdown function is integrated - distinguishing it from the pin-compatible OPA373 family. It is unity-gain stable and specified across −40°C to +125°C, with electrical characteristics guaranteed over 2.7 V to 5.5 V supply, and functional operation supported down to 2.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 6.5 MHz - enables stable closed-loop operation up to ~5 MHz at G = +2 without compensation. |
| Slew rate | 5 V/µs - supports clean 1-MHz, 5-VPP small-signal amplification without distortion. |
| Input offset voltage (max) | 5 mV - limits DC error to ≤0.1% of full-scale in 5-V systems without trimming. |
| Quiescent current | 585 µA - allows continuous operation for >1 year on a 200-mAh coin cell in always-on sensing nodes. |
| Rail-to-rail I/O | Input extends 200 mV beyond rails; output swings within 25 mV of rails - maximizes dynamic range in 2.3–5.5 V supplies. |
| Operating temperature | −40°C to +125°C - qualified for under-hood automotive, industrial control, and outdoor IoT deployments. |
| ESD rating (HBM) | ±3000 V - meets IEC 61000-4-2 Level 3 for robust handling in manufacturing and field service. |
Pinout & Package
OPA374AIDBVTG4 is packaged in a 5-pin SOT-23 (DBV) with 2.90 mm × 1.60 mm body size and exposed pad not present. Pin 1 is marked by a dot; orientation follows TI standard top-view marking convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Output | Amplified signal source; drives resistive loads ≥5 kΩ or capacitive loads ≤250 pF in unity-gain configuration. |
| 2 (V−) | Negative supply | Lowest potential node; must be connected to ground or negative rail - no internal connection to substrate. |
| 3 (+IN) | Noninverting input | High-impedance (10¹³ Ω) node; accepts signals from (V−) −0.2 V to (V+) + 0.2 V without phase inversion. |
| 4 (−IN) | Inverting input | High-impedance node; used in transimpedance, difference, or inverting gain configurations with matched feedback networks. |
| 5 (V+) | Positive supply | Highest potential node; supplies power and defines upper common-mode limit - supports 2.3 V to 5.5 V operation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Extends common-mode range 200 mV beyond both supply rails - eliminates level-shifting circuitry in single-supply sensor interfaces. |
| Low input bias current | ≤10 pA max - preserves signal integrity in high-impedance sources (e.g., pH electrodes, photodiode transimpedance amps). |
| Low quiescent current | 585 µA typical - enables always-on analog signal chains in energy-harvesting and battery-critical designs. |
| High-speed, low-power ratio | 6.5 MHz GBW at 585 µA - achieves >11,000 MHz/A efficiency, outperforming legacy rail-to-rail op amps by 2×. |
| 125°C operation | Full electrical specs guaranteed - supports placement near heat sources (e.g., power converters, motor drivers) without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA374AIDBVR | Same silicon, tape-and-reel packaging (3000 pcs/reel) vs. OPA374AIDBVTG4's cut-tape (250 pcs/reel); identical electrical specs. | No functional difference - selected for high-volume automated assembly where reel feed is required. | Choose OPA374AIDBVR for SMT production lines; OPA374AIDBVTG4 suits prototyping, low-volume builds, or mixed-BOM procurement. |
| MCP6001T-E/OT | Lower bandwidth (1 MHz), higher offset (1.5 mV typ), 100-µA IQ - less speed/power efficiency but wider supply range (1.8–6.0 V). | Better suited for ultra-low-power (<100 µA) or sub-2.3-V applications where 6.5-MHz BW is unnecessary. | Select MCP6001T-E/OT only when supply voltage falls below 2.3 V or when <100-µA IQ is mandatory - not a performance replacement. |
Compared with OPA374AIDBVTG4, OPA374AIDBVR offers identical performance in reel format for volume manufacturing, while MCP6001T-E/OT trades bandwidth and precision for lower quiescent current and extended supply flexibility - making it suitable only for non-demanding, ultra-low-power use cases.

FAQ
What is the maximum operating supply voltage for OPA374AIDBVTG4?
The absolute maximum supply voltage for OPA374AIDBVTG4 is 7 V, but the recommended operating range is 2.3 V to 5.5 V per the datasheet. Operation above 5.5 V risks permanent damage, while operation below 2.3 V may cause degraded AC performance or failure to meet guaranteed specifications. The OPA374AIDBVTG4 is fully characterized from 2.7 V to 5.5 V, with functional operation confirmed down to 2.3 V.
Does OPA374AIDBVTG4 include a shutdown pin?
No, OPA374AIDBVTG4 does not include a shutdown pin. It is a non-shutdown variant of the OPAx374 family. The pin-compatible OPA373 series (e.g., OPA373AIDBVT) provides shutdown functionality with <1 µA standby current, but OPA374AIDBVTG4 operates continuously whenever powered. This simplifies layout and reduces external control complexity in always-on applications.
Can OPA374AIDBVTG4 drive capacitive loads reliably?
Yes, OPA374AIDBVTG4 is unity-gain stable and can drive up to 250 pF with minimal overshoot in G = +1 configuration. For loads exceeding 250 pF, adding a 10-Ω to 20-Ω isolation resistor between the output and capacitive load restores stability. This behavior is verified in Figure 17 of the SBOS279F datasheet and applies directly to OPA374AIDBVTG4 in its 5-pin SOT-23 package.
What is the input common-mode voltage range of OPA374AIDBVTG4?
The input common-mode voltage range of OPA374AIDBVTG4 extends from (V−) −0.2 V to (V+) + 0.2 V - meaning it accepts signals 200 mV beyond both supply rails. This rail-to-rail input capability eliminates the need for external level-shifting circuitry in single-supply systems. However, optimal PSRR, CMRR, and THD are maintained outside the 500-mV transition region near (V+) −1.65 V.
Is OPA374AIDBVTG4 suitable for automotive applications?
OPA374AIDBVTG4 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 where ambient temperatures remain within that range. While not AEC-Q200 certified, its 125°C specification and ±3000-V HBM ESD rating support deployment in non-safety-critical automotive subsystems such as infotainment sensor interfaces and body control modules.
