AS2333M8-13

Overview

The AS2333M8-13 is a dual CMOS operational amplifier from Diodes Incorporated, utilizing chopping stabilization to achieve ultra-low input offset voltage (8μV typical) and near-zero drift. It operates on supply voltages ranging from 1.8V to 5.5V with a quiescent current of 12μA per amplifier. The device features rail-to-rail input and output capabilities, a gain-bandwidth product of 350kHz, and a slew rate of 0.12V/μs. Designed for high-precision applications, it eliminates 1/f noise and crossover distortion while maintaining an operating temperature range from -40°C to +125°C.

Feature Summary

• Chopper-stabilized architecture providing ultra-low input offset voltage and near-zero drift over time and temperature
• Rail-to-rail input and output operation allowing signal sensing beyond the supply rails
• Low quiescent current consumption optimized for battery-powered and low-power applications
• Elimination of 1/f noise and crossover distortion inherent in standard linear amplifiers

Applications

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

Procurement Notes

Verify the specific MSOP-8 package variant when ordering, as the AS2333 series includes SO-8 and U-DFN3030-8 options. Confirm that the -13 suffix corresponds to the Tape & Reel packing quantity of 2500 units. Ensure design requirements align with the specified electrical characteristics for single-supply operation between 1.8V and 5.5V.

Selection Notes

Select this component for applications requiring high precision at low frequencies where zero-drift performance is critical. The MSOP-8 package offers a compact footprint suitable for space-constrained designs. Consider the 350kHz bandwidth and 0.12V/μs slew rate for signal fidelity requirements. Verify thermal management needs based on the junction-to-ambient resistance for the MSOP-8 package.

Part Context

The AS2333M8-13 belongs to the AS2333 family of micropower CMOS zero-drift operational amplifiers manufactured by Diodes Incorporated. This family shares identical electrical specifications but differs in physical packaging. The M8 designation specifically identifies the MSOP-8 surface-mount package, distinguishing it from the SO-8 and U-DFN3030-8 variants within the same functional group.

FAQ

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

The chopper-stabilized architecture eliminates 1/f noise, making the AS2333 particularly effective for accurate, high-gain amplification at lower frequencies. However, the clock frequency of the chopper establishes a practical limit on signal fidelity at higher frequencies.

What is the common-mode voltage range capability?

The high-impedance inputs allow a common-mode voltage range that extends 100mV beyond both the negative and positive supply rails, facilitating sensing near ground or system VDD.
