Product details
Overview
OPA2374AIDCNR 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-fidelity signal conditioning in space-constrained, battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the OPA2374AIDCNR datasheet, OPA2374AIDCNR pinout, OPA2374AIDCNR application, or OPA2374AIDCNR equivalent, key selection criteria include its rail-to-rail I/O swing (within 25 mV of rails), low input bias current (≤10 pA), 5 mV max input offset, and operation across –40°C to +125°C - critical for precision analog front-ends in industrial and automotive environments.
Technical Context
The OPA2374AIDCNR employs complementary N- and P-channel input stages to achieve rail-to-rail input common-mode range extending 200 mV beyond both supply rails. Its class AB output stage supports rail-to-rail output swing under light loads (≤100 kΩ), with typical output voltage within 18 mV of V+ or V– at 25°C.
No shutdown function is integrated - distinguishing it from the pin-compatible OPA2373 family. It is unity-gain stable and specified for operation from 2.3 V to 5.5 V, with full performance guaranteed from –40°C to +125°C per JEDEC JESD22-A108.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 6.5 MHz - enables stable closed-loop operation up to ~100 kHz with G = 100, suitable for anti-aliasing and active filter stages. |
| Slew rate | 5 V/µs - supports clean 100-kHz, 5-VPP sine wave output without distortion in unity-gain buffer configurations. |
| Input offset voltage (max) | 5 mV - limits DC error to ≤0.1% of full-scale in 5-V systems, reducing need for system-level trimming. |
| Input bias current (max) | 10 pA - preserves signal integrity in high-impedance sensor interfaces (e.g., pH electrodes, photodiode transimpedance amps). |
| Supply voltage range | 2.3 V to 5.5 V - allows direct interfacing with Li-ion, Li-Po, and 3.3-V logic rails without level-shifting or LDO overhead. |
| Operating temperature | –40°C to +125°C - qualified for under-hood automotive, motor control feedback, and industrial PLC analog I/O modules. |
| Quiescent current | 585 µA per channel - enables dual-opamp functionality in always-on, ultra-low-power IoT node signal chains. |
Pinout & Package
OPA2374AIDCNR is housed in an 8-pin SOT-23 package (DCN) measuring 2.90 mm × 1.63 mm × 1.00 mm, with exposed thermal pad connected internally to V– for enhanced thermal dissipation in compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream ADC inputs or low-impedance loads; rail-to-rail swing supports full dynamic range utilization. |
| 2 | –IN A | Inverting input, channel A - accepts feedback networks for inverting configurations; high impedance minimizes loading on preceding stages. |
| 3 | +IN A | Noninverting input, channel A - used in unity-gain buffers or high-Z sensor interfaces; immune to phase inversion beyond rails when current-limited. |
| 4 | V– | Negative supply terminal - must be connected to ground or negative rail; internal thermal pad tied to this pin for thermal management. |
| 5 | +IN B | Noninverting input, channel B - independent input for second signal path; enables dual-channel differential sensing or signal splitting. |
| 6 | –IN B | Inverting input, channel B - supports matched dual-path filtering or instrumentation amplifier front-end topologies. |
| 7 | OUT B | Amplifier B output - electrically isolated from OUT A; allows simultaneous processing of two analog signals on one die. |
| 8 | V+ | Positive supply terminal - accepts 2.3–5.5 V; internal ESD protection diodes clamp inputs to V+ and V– rails. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends 200 mV beyond V+ and V– - enables direct interfacing with sensors operating near supply rails (e.g., bridge outputs, DACs). |
| Rail-to-rail output swing | Within 18 mV of V+ or V– at 100-kΩ load - maximizes usable signal headroom in low-voltage systems (e.g., 3.3-V ADC reference spans). |
| Low input bias current | ≤10 pA maximum - prevents significant voltage drop across >10-MΩ source impedances, preserving accuracy in electrochemical and piezoelectric sensing. |
| High PSRR and CMRR | ≥128 dB PSRR and ≥90 dB CMRR at DC - rejects power-supply ripple and common-mode noise in noisy industrial environments. |
| Unity-gain stability | Stable with capacitive loads ≤250 pF at G = +1 - eliminates need for external compensation in sensor buffering and ADC driver applications. |

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 |
|---|---|---|---|
| OPA2376AIDR | Lower input offset (25 µV typ vs 1 mV typ), lower noise (7.5 nV/√Hz), but higher quiescent current (760 µA/ch) and no 125°C rating. | Better for precision DC-coupled instrumentation; unsuitable for extended-temperature automotive or industrial use. | Select OPA2376AIDR only if offset and noise dominate over temperature range and power budget. |
| MCP6022-E/SN | Higher input offset (2.5 mV max), wider supply range (2.7–6.0 V), but lacks 125°C rating and has higher IB (100 pA max). | Acceptable for commercial-grade portable equipment; not recommended for under-hood or factory-floor deployments. | Choose MCP6022-E/SN only for cost-sensitive, non-extended-temp designs where 125°C operation is unnecessary. |
Compared with OPA2374AIDCNR, OPA2376AIDR offers superior DC precision at the expense of thermal robustness and power efficiency, while MCP6022-E/SN trades specification margin for broader vendor availability and lower unit cost - making OPA2374AIDCNR the optimal balance of extended temperature, low power, and rail-to-rail performance in harsh environments.

FAQ
What is the maximum operating temperature for OPA2374AIDCNR?
The OPA2374AIDCNR is fully specified and tested from –40°C to +125°C, with absolute maximum junction temperature rated at 150°C. This makes it suitable for under-hood automotive applications, industrial motor drives, and outdoor environmental sensors where ambient temperatures exceed 85°C.
Does OPA2374AIDCNR include a shutdown feature?
No, OPA2374AIDCNR does not include a shutdown function. It is a dual-channel op-amp with continuous operation. For shutdown capability in the same family, consider the pin-compatible OPA2373AIDR or OPA2373AIDCKR, which integrate enable pins and reduce quiescent current to <1 µA per channel in standby mode.
What is the input common-mode voltage range of OPA2374AIDCNR?
The input common-mode voltage range of OPA2374AIDCNR extends from (V–) – 0.2 V to (V+) + 0.2 V - i.e., 200 mV beyond both supply rails. This rail-to-rail input capability allows direct interfacing with sensors and DACs operating near the supply boundaries without external level-shifting circuitry.
Can OPA2374AIDCNR drive capacitive loads reliably?
Yes, OPA2374AIDCNR is unity-gain stable and can drive up to 250 pF of pure capacitive load without oscillation. For larger loads or inductive traces, adding a small series resistor (10–20 Ω) between the output and load improves phase margin and ensures stable step response - as validated in TI's SBOS279F datasheet Figure 17.
What package type is used for OPA2374AIDCNR?
OPA2374AIDCNR uses the 8-pin SOT-23 (DCN) package, measuring 2.90 mm × 1.63 mm × 1.00 mm, with an exposed thermal pad connected internally to V–. This compact, surface-mount package supports high-density PCB layouts and provides improved thermal performance over standard SOIC variants.
