AZV832MMTR-G1

Overview

The AZV832MMTR-G1 is a dual-channel, low bias current, low voltage, rail-to-rail input/output CMOS operational amplifier manufactured by Diodes Incorporated. It operates from a single supply of 1.6V to 5.5V or dual supplies of ±0.8V to ±2.5V. Key electrical parameters include a typical unity gain bandwidth of 1MHz, a maximum slew rate of 450mV/µs at 5V, and an ultra-low input bias current of 1pA. The device features a typical input offset voltage of 0.5mV (maximum 2.5mV) and consumes 70µA per channel. It is housed in an MSOP-8 package.

Feature Summary

• Rail-to-rail input and output capability for maximum signal swings in low supply voltage applications
• Ultra-low input bias current of 1pA suitable for high impedance sensor interfaces
• Unity gain stable with a 1MHz gain bandwidth product

Applications

• Photodiode amplification
• Piezoelectric sensors
• Integrators
• Battery-powered instrumentation
• Pulse blood oximeters and glucose meters

Procurement Notes

Verify the specific ordering suffix 'TR' indicates tape and reel packaging rather than tube configuration. Confirm RoHS compliance via the 'G1' designation. Ensure the MSOP-8 package matches the required footprint. Check humidity sensitivity levels if moisture-prone environments are involved.

Selection Notes

Select this component when low power consumption and minimal input bias current are critical. The rail-to-rail I/O allows operation near supply rails without significant signal loss. Verify that the 1MHz bandwidth meets the frequency requirements of the target application circuit.

Part Context

This part belongs to the AZV831/AZV832 family of low voltage CMOS operational amplifiers. While the AZV831 provides a single channel, the AZV832 offers dual channels in the same technology node. The MMTR-G1 suffix specifically denotes the dual-channel variant in MSOP-8 tape and reel packaging.

Replacement Considerations

AZV832MTR-G1 serves as a direct functional equivalent in SOIC-8 packaging.
