MAX9030AUT+T

Overview

The MAX9030AUT+T is a single-supply analog comparator from the MAX9030 family, housed in a 6-pin SOT23 package. It operates within a voltage range of +2.5V to +5.5V and consumes 35µA per comparator at typical conditions. The device features a propagation delay of 188ns with a 4mV internal hysteresis. Input offset voltage is typically ±1mV, with an input bias current of 8nA. It supports rail-to-rail output swings and includes a shutdown mode reducing supply current to 0.05µA.

Feature Summary

• Includes a dedicated shutdown pin for power conservation
• Features built-in 4mV hysteresis for noise immunity
• Provides rail-to-rail output swing capability
• Operates on a single supply down to +2.5V

Applications

• Battery-powered portable systems
• Mobile communications devices
• Sensor signal detection circuits
• Threshold detectors and discriminators

Procurement Notes

Verify the specific ordering suffix AUT+T corresponds to the 6-pin SOT23 package variant rather than the SC70 option. Confirm that the lead-free designation aligns with project compliance requirements. Ensure the tape-and-reel packaging format matches automated assembly capabilities. Validate the -40°C to +125°C temperature range against environmental specifications.

Selection Notes

Select this component when a low-cost, ultra-small footprint is required alongside power-saving shutdown functionality. It is suitable for applications needing rail-to-rail outputs and internal hysteresis without external components. Consider alternative models if dual or quad channels are needed instead of a single comparator configuration.

Part Context

This part belongs to the MAX9030/MAX9031/MAX9032/MAX9034 series of low-cost, ultra-small single/dual/quad comparators. The MAX9030 specifically denotes the single-channel version equipped with a shutdown feature. Other variants in the series include the MAX9031 (single without shutdown), MAX9032 (dual), and MAX9034 (quad).

Replacement Considerations

Direct substitutes within the same family include the MAX9030AXT+T, which offers identical electrical characteristics but utilizes a 6-pin SC70 package instead of the SOT23 form factor.
