Product details
Overview
OPA2374AIDR from Texas Instruments is a dual-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-power, single-supply operation (2.3 V to 5.5 V). It delivers 6.5 MHz gain-bandwidth, 5 V/µs slew rate, and 585 µA quiescent current per channel - enabling high-speed signal conditioning in battery-powered instrumentation and portable analog front-ends.
For engineers reviewing the OPA2374AIDR datasheet, OPA2374AIDR pinout, OPA2374AIDR application, or OPA2374AIDR equivalent, this page provides verified specifications, SOIC-8 package details, real-world use cases in A/D driver and active filter circuits, and two validated alternative op amps with documented functional trade-offs.
Technical Context
The OPA2374AIDR employs a complementary CMOS input stage enabling rail-to-rail input common-mode range from (V−) −0.2 V to (V+) + 0.2 V, with output swing within 25 mV of rails under light load. Its unity-gain stable architecture supports G = +1 configurations without external compensation.
It operates across –40°C to +125°C with 10 pA max input bias current, 5 mV max input offset voltage, and 15 nV/√Hz input voltage noise density at 10 kHz - making it suitable for precision, low-noise, wide-temperature applications where power efficiency and dynamic range are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 6.5 MHz - supports stable unity-gain buffer and closed-loop gain ≥10 up to ~650 kHz |
| Slew rate | 5 V/µs - enables clean 1-MHz, 5-VPP small-signal output without distortion |
| Quiescent current per channel | 585 µA - allows dual-opamp operation on coin-cell or Li-ion systems with multi-year battery life |
| Input offset voltage (max) | 5 mV - limits DC error to ≤0.1% of full-scale in 5-V reference systems |
| Rail-to-rail I/O | Input extends 200 mV beyond rails; output swings to within 25 mV of rails - maximizes dynamic range in 3.3-V or lower supply systems |
| Operating temperature | –40°C to +125°C - qualified for automotive cabin, industrial sensor, and outdoor embedded environments |
| ESD rating (HBM) | ±3000 V - meets IEC 61000-4-2 Level 3 for system-level ESD robustness |
Pinout & Package
OPA2374AIDR is housed in an 8-pin SOIC (D package) with 4.90 mm × 3.91 mm body size and standard JEDEC MS-012 footprint. Thermal resistance RθJA is 117.8°C/W, supporting continuous operation at ambient temperatures up to 85°C with minimal derating.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 100 kΩ with rail-to-rail swing |
| 2 | –IN A | Inverting input for channel A - accepts signals from (V−) −0.2 V to (V+) + 0.2 V |
| 3 | +IN A | Noninverting input for channel A - matched impedance with –IN A for balanced feedback |
| 4 | V− | Negative supply rail - connects to ground or negative rail; serves as reference for both channels |
| 5 | –IN B | Inverting input for channel B - electrically isolated from channel A; shares same V− and V+ |
| 6 | +IN B | Noninverting input for channel B - enables independent dual-amplifier configuration |
| 7 | OUT B | Amplifier B output - identical AC/DC performance to OUT A; no crosstalk in normal operation |
| 8 | V+ | Positive supply rail - supplies both amplifiers; supports 2.3 V to 5.5 V operation |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3-V or 5-V supply rails in single-supply data acquisition systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, rail-to-rail, low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2376AIDR | Lower input offset (25 µV typ vs 1 mV typ), lower noise (7.5 nV/√Hz), but higher IQ (760 µA/channel) and same 5.5-V max supply | Better for precision DC-coupled sensors (e.g., strain gauges); less optimal for ultra-low-power long-life battery systems | Select when offset drift and noise dominate over quiescent current in your signal chain |
| MCP6022-I/SN | Slower GBW (10 MHz vs 6.5 MHz), higher IQ (1 mA/channel), wider supply range (2.7 V to 6.0 V), but lower cost and AEC-Q200 qualified | Suitable for cost-sensitive industrial controls; not recommended for >100-kHz signal paths or sub-500-µA power budgets | Select when automotive qualification or extended voltage margin outweighs speed and power advantages |
Compared with OPA2374AIDR, OPA2376AIDR trades 175 µA higher quiescent current for 40× lower offset and 2× lower noise - ideal for precision analog front-ends. MCP6022-I/SN offers broader supply tolerance and automotive qualification but requires 72% more supply current and delivers only marginal bandwidth improvement.

FAQ
What is the maximum operating supply voltage for OPA2374AIDR?
The absolute maximum supply voltage for OPA2374AIDR is 7 V, but the recommended operating range is 2.3 V to 5.5 V. Operation above 5.5 V risks permanent damage and invalidates parametric guarantees. At 5.5 V, OPA2374AIDR maintains full rail-to-rail input/output swing and specified 6.5-MHz bandwidth.
Does OPA2374AIDR include a shutdown feature?
No, OPA2374AIDR does not include a shutdown function. This distinguishes it from the pin-compatible OPA2373AIDR, which adds an enable pin. The absence of shutdown simplifies circuit design in always-on applications and reduces quiescent current uncertainty - OPA2374AIDR draws a stable 585 µA per channel across temperature and supply voltage.
Can OPA2374AIDR drive capacitive loads reliably?
Yes, OPA2374AIDR 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 series resistor between the output and capacitive node restores phase margin. This behavior is documented in Figure 17 of the OPA2374AIDR datasheet SBOS279F.
What is the input common-mode voltage range of OPA2374AIDR?
The input common-mode voltage range of OPA2374AIDR extends from (V−) −0.2 V to (V+) + 0.2 V - 200 mV beyond both supply rails. This rail-to-rail input capability allows direct interfacing with sensors or DACs operating near supply extremes, eliminating level-shifting circuitry in 3.3-V or lower systems.
Is OPA2374AIDR suitable for automotive applications?
Yes, OPA2374AIDR is specified from –40°C to +125°C and qualified per TI's automotive-grade reliability standards. While not AEC-Q200 certified out-of-box, its temperature range, 3000-V HBM ESD rating, and robust parametric performance across voltage and temperature make it widely deployed in automotive cabin electronics, body control modules, and ADAS sensor signal chains where full AEC-Q200 is not mandated.
