What are the key features of OPA374AIDG4?
- Rail-to-rail input and output (RRIO) for maximum dynamic range at low supply voltages of 2.5V to 5.5V
- Ultra-low bias current of 10pA typical enabling high-impedance sensor interfacing without loading
- 90dB typical common-mode rejection ratio (CMRR) for accurate differential signal amplification
- Voltage-feedback architecture with internal frequency compensation for stable single-supply operation
- Industry-standard 8-pin SOIC package (tube) compatible with broad PCB assembly infrastructure
What is OPA374AIDG4 used for?
The OPA374AIDG4 is used in precision sensor signal conditioning, battery-powered instrumentation, and single-supply analog front-ends where rail-to-rail swing is required at 5V or lower supply voltages. Its 10pA bias current and 90dB CMRR make it suitable for photodiode transimpedance amplifiers, bridge sensor amplifiers, and medical monitoring circuits. The SOIC-8 package integrates easily into space-efficient mixed-signal PCB layouts.

Frequently Asked Questions
What supply voltage range does the OPA374AIDG4 support and how does rail-to-rail operation help?
The OPA374AIDG4 operates from a single supply of 2.5V to 5.5V or a dual supply of ±1.25V to ±2.75V. Its rail-to-rail input and output swings allow the output to reach within millivolts of both supply rails, maximizing usable signal range at low voltages and improving accuracy in single-supply 3.3V and 5V systems.
How low is the bias current of OPA374AIDG4 and which applications benefit from it?
The OPA374AIDG4 has a maximum bias current of 10pA (0.00001µA) at 25°C, making it exceptionally suitable for high-impedance sources such as photodiodes, pH electrodes, and capacitive pressure sensors. Such low bias current prevents loading errors that would distort readings from sensors with source impedances in the megaohm to gigaohm range.
What is the CMRR specification of the OPA374AIDG4 and why does it matter in sensor designs?
The OPA374AIDG4 achieves a typical common-mode rejection ratio (CMRR) of 90dB with a minimum guaranteed 60dB. High CMRR means that noise or interference voltages common to both inputs — such as 50/60Hz mains coupling — are rejected, preserving the accuracy of differential measurements from bridge strain gauges, thermocouples, and pressure transducers.
When would a designer choose OPA374AIDG4 in SOIC-8 tube format over a smaller package alternative?
Designers choosing the OPA374AIDG4 in SOIC-8 tube packaging typically prioritize ease of hand-soldering during prototyping or have existing PCB footprints sized for 1.27mm-pitch SOIC. For volume production needing smaller footprint, the same device may be available in SOT-23-5 or SC-70; the SOIC-8 variant suits lower-volume or prototype-stage builds where tube packaging simplifies manual assembly.
