MAX9031AXK+T

Overview

The MAX9031AXK+T is a single-supply analog comparator optimized for portable applications. It operates within a voltage range of +2.5V to +5.5V and consumes 35µA per comparator over the -40°C to +125°C temperature range. The device features a 188ns propagation delay, 4mV built-in hysteresis, and rail-to-rail output swing. It utilizes a 5-pin SC70 package.

Feature Summary

• Rail-to-rail output stage reduces switching current during transitions
• Internal 4mV hysteresis prevents oscillations with slow-moving signals
• No phase reversal occurs for overdriven inputs

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and lead-free status. Ensure the component matches the required operating temperature range and supply voltage specifications for your design. Confirm availability through authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when space constraints require a 5-pin ultra-small footprint. It is suitable for designs needing low power consumption and noise immunity without external hysteresis components. Consider the MAX9030 if shutdown functionality is required instead.

Part Context

This part belongs to the MAX9030/MAX9031/MAX9032/MAX9034 family of low-cost comparators. While the MAX9030 includes a shutdown pin, the MAX9031 provides a single comparator in a tiny 5-pin SC70 or SOT23 package. The MAX9032 and MAX9034 offer dual and quad configurations respectively.

Replacement Considerations

The MAX9031AUK+T serves as a pin-compatible alternative utilizing the SOT23-5 package instead of the SC70-5 package found in the MAX9031AXK+T.
