MAX9034AUD+

Overview

The MAX9034AUD+ is a quad comparator from the MAX9030/MAX9031/MAX9032/MAX9034 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from +2.5V to +5.5V or dual supplies of ±1.25V to ±2.75V. The device features a propagation delay of 188ns and consumes 35µA of supply current per comparator over an operating temperature range of -40°C to +125°C. It includes internal 4mV hysteresis for noise immunity and offers rail-to-rail output swing without phase reversal for overdriven inputs.

Feature Summary

• Quad comparator configuration with built-in 4mV hysteresis for noise immunity
• Rail-to-rail output swing capability with reduced switching current
• Low power consumption optimized for portable applications
• No phase reversal for overdriven inputs

Applications

• Battery-powered systems
• Portable electronics
• Mobile communications devices
• Sensor signal detection circuits
• Photodiode preamplifiers

Procurement Notes

Verify the specific suffix AUD+ indicates the TSSOP package variant when sourcing. Confirm RoHS compliance status as indicated by the plus sign in the part number. Ensure the ordering information matches the required pin count and thermal characteristics for your PCB layout design requirements.

Selection Notes

Select this component when a quad comparator solution is needed within space-constrained designs. Consider the 14-pin TSSOP package availability against alternative packages like SOIC if footprint constraints differ. Evaluate the 188ns propagation delay against system timing requirements before finalizing the selection.

Part Context

This part belongs to the MAX903x series of low-cost, ultra-small comparators designed primarily for single-supply applications. The MAX9034 specifically provides four independent comparator channels in a compact form factor, distinguishing it from the single (MAX9030), dual (MAX9032), and other variants within the same product family.

Replacement Considerations

Direct substitutes include other members of the MAX903x family such as the MAX9034ASD+ which shares identical electrical specifications but utilizes a 14-pin SOIC package instead of TSSOP.
