MAX9034AUD-T

Overview

The MAX9034AUD-T is a quad, low-cost analog comparator from Analog Devices/Maxim Integrated, housed in a 14-pin TSSOP package. It operates on a single supply voltage ranging from +2.5V to +5.5V and consumes 35µA of supply current per channel across the -40°C to +125°C temperature range. The device features a propagation delay of 188ns, an internal hysteresis of 4mV, and rail-to-rail output swing. Input common-mode voltage extends from the negative supply to within 1.1V of the positive supply.

Feature Summary

• Quad configuration with ultra-small footprint suitable for portable applications
• Internal 4mV hysteresis provides noise immunity and prevents oscillations
• Rail-to-rail output swings minimize power-supply glitches during transitions
• No phase reversal occurs for overdriven inputs

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm that the 'AUD' designation corresponds to the 14-pin TSSOP package variant. Ensure compliance with RoHS standards as indicated by the '+' suffix in the base part number. Cross-reference the manufacturer's ordering information to validate availability and production status before finalizing procurement plans.

Selection Notes

Select this component when a quad comparator solution is required in space-constrained designs. It is appropriate for applications needing low quiescent current and high input impedance. Consider the 188ns propagation delay for timing-sensitive digital line receivers. Verify that the 4mV internal hysteresis meets the noise margin requirements without external feedback components.

Part Context

This device belongs to the MAX903x family of low-cost, ultra-small comparators optimized for single-supply operation. The MAX9034 specifically offers four independent channels in a compact 14-pin TSSOP package. It shares core electrical characteristics with the MAX9030, MAX9031, and MAX9032 variants, differing primarily in channel count and physical package dimensions.

Replacement Considerations

Direct substitutes include other members of the MAX903x family such as the MAX9032 for dual-channel needs. Verify pin compatibility and package dimensions when replacing with similar quad comparators from other manufacturers. Ensure equivalent propagation delay and supply current specifications are met for functional parity.
