AZV831KTR-G1

Overview

The AZV831KTR-G1 is a single-channel rail-to-rail input and output CMOS operational amplifier manufactured by Diodes Incorporated. It operates from a single supply voltage of 1.6V to 5.5V or dual supplies of ±0.8V to ±2.5V. Key electrical parameters include a typical supply current of 70 µA per channel, an ultra-low input bias current of 1pA, and a typical input offset voltage of 0.5mV with a maximum of 2.5mV. The device features a gain bandwidth product of 1.0MHz and a slew rate of 0.45V/µs at 5.0V. It is housed in a SOT-23-5 package and supports an ambient operating temperature range from -40°C to +85°C.

Procurement Notes

Verify the specific ordering suffix 'KTR' corresponds to the SOT-23-5 tape and reel packaging configuration as defined in the manufacturer's ordering information table. Confirm that the 'G1' suffix indicates RoHS compliance and green material status. Ensure the component source matches the BCD Semiconductor Manufacturing Limited datasheet specifications provided.

Selection Notes

Select this component for designs requiring low power consumption and minimal input bias current in portable devices. The rail-to-rail I/O functionality allows for optimal dynamic range when operating near supply rails. Verify that the 1.0MHz bandwidth meets the frequency response requirements of the target application circuit.

Part Context

This part belongs to the AZV831/2 family of low voltage, low bias current CMOS operational amplifiers. The AZV831 variant provides a single amplifier channel, whereas the AZV832 offers dual channels. Both share identical electrical characteristics but differ in package options and channel count to suit different space and integration constraints.
