Overview
The MAX9034AUD is a quad comparator in a 14-pin TSSOP package. It operates from +2.5V to +5.5V single supply or ±1.25V to ±2.75V dual supplies. Supply current is 35µA per comparator. Propagation delay is 188ns at 100mV overdrive and 228ns at 10mV. Input offset voltage is ±1mV typical, with internal hysteresis of 4mV. Common-mode range extends from VSS to VDD - 1.1V. Output swings rail-to-rail.
Feature Summary
- Quad configuration with rail-to-rail output capability
- Internal 4mV hysteresis for noise immunity
- Low power consumption optimized for portable applications
- No phase reversal 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 'AUD' corresponds to the 14-pin TSSOP package and industrial temperature range (-40°C to +125°C). Confirm RoHS compliance status based on the '+' designation. Ensure ordering documentation matches the exact manufacturer part number to avoid pinout mismatches with similar SOIC variants.
Selection Notes
Select this component when four independent comparators are required in a compact surface-mount footprint. The device is suitable for low-voltage single-supply designs down to 2.5V. Consider the 188ns propagation delay for timing-sensitive applications. Verify that the input common-mode range requirements align with the specified VDD - 1.1V limit.
Part Context
This part belongs to the MAX903x family of low-cost, ultra-small comparators. While the MAX9030 includes shutdown functionality, the MAX9034 provides four channels without shutdown control. It complements the single (MAX9031) and dual (MAX9032) versions within the same series, sharing identical electrical characteristics and performance metrics.
Replacement Considerations
The MAX9034ASD+ serves as a direct physical replacement using the 14-pin SOIC package instead of TSSOP. Both variants share identical electrical specifications and pinouts. Verify board space constraints before substituting the wider SOIC package for the narrower TSSOP version.
