AS2333FGE-13A

Overview

The AS2333FGE-13A is a dual CMOS zero-drift operational amplifier manufactured by Diodes Incorporated. It utilizes chopping stabilization to achieve an ultra-low input offset voltage of 8μV and near-zero drift over time and temperature. The device operates on supply voltages ranging from 1.8V to 5.5V with a quiescent current of 12μA per amplifier. It features rail-to-rail input and output capabilities, a gain-bandwidth product of 350kHz, and a slew rate of 0.12V/μs. The component is housed in a U-DFN3030-8 (Type E) package and is specified for operation across a temperature range of -40°C to +125°C.

Feature Summary

• Chopper-stabilized architecture eliminates 1/f noise and crossover distortion while providing ultra-low input offset voltage and near-zero drift.
• Rail-to-rail input and output stages allow the common-mode range to extend 100mV beyond the supply rails.
• Optimized for low-voltage single-supply applications with high-precision performance and low power consumption.

Applications

• Battery-powered instruments
• Handheld test equipment
• Medical instrumentation
• Sensor signal conditioning
• Low-voltage current sensing

Procurement Notes

Verify the specific ordering suffix '-13A' corresponds to the U-DFN3030-8 (Type E) package configuration as documented in the manufacturer's ordering information. Confirm that the component meets all required environmental standards, including RoHS compliance and halogen-free specifications, before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring high precision at low frequencies without the influence of flicker noise. The zero-drift technology makes it suitable for amplifying small sensor signals where long-term stability is critical. Ensure the application voltage remains within the 1.8V to 5.5V range to maintain optimal performance characteristics.

Part Context

This part belongs to the AS2333 series of micropower CMOS zero-drift operational amplifiers. The series includes variants such as the AS2333S-13 and AS2333M8-13, which offer identical electrical performance but utilize different packaging formats like SO-8 and MSOP-8. The FGE suffix specifically identifies the U-DFN3030-8 package type within this family.

Replacement Considerations

Direct substitutes include other AS2333 variants with different packages, such as AS2333S-13 or AS2333M8-13, provided the physical footprint allows for adaptation. Automotive-grade versions like the AS2333Q may be considered if higher reliability standards are required.

FAQ

How does the chopper-stabilization technique affect the frequency response?

The chopper-stabilized architecture eliminates 1/f noise, making the amplifier ideal for low-frequency applications. However, the clock frequency of the chopper establishes a practical limit on signal fidelity at higher frequencies compared to linear operational amplifiers.

What is the input common-mode voltage range?

The input common-mode voltage range extends 0.1V beyond the negative and positive supply rails, allowing the device to sense signals near ground or system VDD effectively.
