What are the key features of OPA2338UAG4?
- Dual rail-to-rail output amplifier enabling output signal swing within millivolts of both supply rails in a single 5.5 V supply system
- Ultra-low bias current of 0.00001 µA (10 pA typical) minimizing loading on high-impedance sensor sources
- 90 dB common-mode rejection ratio ensuring excellent noise immunity in single-supply differential signal conditioning circuits
What is OPA2338UAG4 used for?
The OPA2338UAG4 is well-suited for precision single-supply signal conditioning circuits in battery-operated portable instruments, where its rail-to-rail output maximizes dynamic range from a 5 V or lower supply. Its ultra-low input bias current of 10 pA makes it an excellent choice for interfacing with high-impedance sensors such as photodiodes and pH electrodes. The dual-channel configuration in a compact 8-pin SOIC package allows two independent signal paths to be implemented on minimal PCB area.

Frequently Asked Questions
What supply voltage range and output swing does the OPA2338UAG4 support?
The OPA2338UAG4 operates from a single supply of 2.7 V to 5.5 V or a dual supply up to ±2.75 V, with a rail-to-rail output that swings to within approximately 50 mV of either supply rail, maximizing usable dynamic range in low-voltage signal conditioning designs.
For a high-impedance photodiode transimpedance amplifier, how suitable is the OPA2338UAG4?
The OPA2338UAG4 is a strong candidate for transimpedance amplifier stages because its input bias current of only 0.00001 µA (10 pA) introduces negligible offset voltage across high-value feedback resistors of 1 MΩ or more. The 74 dB minimum CMRR also helps reject power supply noise, and the 90 dB typical CMRR supports accurate single-ended output in single-supply photodiode circuits.
How does the OPA2338 differ from the single-channel OPA338, and when should you choose the dual version?
The OPA2338UAG4 integrates 2 independent op-amp channels in the same 8-pin SOIC footprint that a single OPA338 occupies, effectively halving the per-channel PCB area and board cost. Choose the dual OPA2338 when your design requires 2 amplification or filtering stages and printed circuit board space is constrained, such as in portable medical or industrial sensor modules.
What is the input offset voltage specification for the OPA2338UAG4, and how does it affect DC accuracy?
The OPA2338UAG4 has a maximum input offset voltage of 3500 µV (3.5 mV) at room temperature. In a gain-of-10 configuration this offset produces up to 35 mV of DC error at the output, so for precision DC measurement applications requiring better than 1 mV accuracy, a lower-offset alternative or external offset trimming should be considered.
