Texas Instruments OPA2374AIDCNRG4

Overview

OPA2374AIDCNRG4 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, with input offset voltage ≤5 mV and input bias current ≤10 pA - enabling precision signal conditioning in battery-powered sensor interfaces and portable data acquisition systems.

For engineers reviewing the OPA2374AIDCNRG4 datasheet, OPA2374AIDCNRG4 pinout, OPA2374AIDCNRG4 application, or OPA2374AIDCNRG4 equivalent, key selection criteria include its rail-to-rail I/O swing (≤25 mV from rails), extended common-mode range (200 mV beyond rails), operation up to 125°C, and 8-pin SOT-23 package - critical for space-constrained, low-voltage analog front-ends requiring high AC performance and low power.

Technical Context

The OPA2374AIDCNRG4 implements a complementary CMOS input stage (N- and P-channel differential pairs) enabling rail-to-rail input operation with a 200-mV beyond-rail common-mode range. Its class AB output stage supports rail-to-rail output swing down to 18 mV from rails under light loads (100 kΩ).

It operates without shutdown functionality (distinguishing it from the OPA2373 family), draws only 585 µA per amplifier at 25°C, and maintains stable unity-gain performance with capacitive loads up to 250 pF - making it suitable for driving ADC inputs and active filters in compact, thermally constrained designs.

FAQ

What is the maximum operating temperature for OPA2374AIDCNRG4?

The OPA2374AIDCNRG4 is fully specified and tested from –40°C to +125°C ambient temperature. This extended range is validated across all key parameters including input offset voltage, CMRR, and open-loop gain - making OPA2374AIDCNRG4 suitable for under-hood automotive, motor-control feedback, and industrial edge-node deployments where ambient temperatures exceed 85°C.

Does OPA2374AIDCNRG4 include a shutdown feature?

No, OPA2374AIDCNRG4 does not include a shutdown function. It belongs to the OPA2374 family, which lacks enable/disable control pins - unlike the pin-compatible OPA2373 family. The OPA2374AIDCNRG4 operates continuously when powered; for low-quiescent applications requiring sleep mode, consider the OPA2373AIDCNR instead.

What is the input common-mode voltage range of OPA2374AIDCNRG4?

The input common-mode voltage range of OPA2374AIDCNRG4 extends from (V−) −0.2 V to (V+) + 0.2 V - meaning it accepts signals 200 mV beyond both supply rails. This is enabled by a complementary CMOS input stage. Operation outside this range (but within absolute max ratings) is possible with current limiting, though PSRR and CMRR degrade in the 500-mV transition region near (V+) −1.65 V.

Can OPA2374AIDCNRG4 drive a 100-pF capacitive load stably at unity gain?

Yes, OPA2374AIDCNRG4 is unity-gain stable and characterized to drive up to 250 pF capacitive loads without oscillation or excessive overshoot. At 100 pF, typical small-signal overshoot is <5% with settling time <1 µs to 0.1%. For loads >250 pF, adding a 10-Ω to 20-Ω series resistor between amplifier output and capacitance restores phase margin and stability.

What package type is used for OPA2374AIDCNRG4?

OPA2374AIDCNRG4 uses the 8-pin SOT-23 (DCN) package, measuring 2.90 mm × 1.63 mm × 1.00 mm. It features an exposed thermal pad on the underside, which must be soldered to a V−-connected copper pour to achieve specified thermal performance (RθJA = 171.3°C/W). This compact footprint supports high-density PCB layouts in space-constrained portable electronics.
