MAX9101ESA+T

Overview

The MAX9101ESA+T is a micropower analog comparator from Analog Devices, optimized for single-supply operation between 1.0V and 5.5V. It features an open-drain output stage suitable for mixed-voltage designs. The device consumes 5μA quiescent current with a propagation delay under 4μs. Input common-mode range extends to the negative rail, and it operates within a temperature range of -40°C to +85°C in an SO-8 package.

Feature Summary

• Ultra-low voltage operation down to 1.0V
• Open-drain output stage for mixed-voltage compatibility
• Micropower consumption of 5μA
• Wide input common-mode range including the negative rail

Applications

• Single-cell battery-powered systems
• Portable electronic equipment
• Battery-powered instrumentation
• Logic-level translation circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free packaging specifications against the latest datasheet revision. Ensure ordering suffixes match required tape-and-reel quantities if applicable. Validate supply chain integrity to avoid counterfeit components.

Selection Notes

Select this part when low quiescent current and wide input common-mode range are critical. The open-drain output requires an external pull-up resistor, making it ideal for interfacing with different logic voltage levels. Consider the MAX9100 variant if push-pull output drive is preferred over open-drain flexibility.

Part Context

This component belongs to the MAX9100/MAX9101 family of micropower comparators designed for portable applications. It shares core electrical characteristics with the MAX9100 but differs in output topology. The series targets battery-operated devices requiring minimal power draw while maintaining reliable signal comparison capabilities.

Replacement Considerations

MAX9100ESA+T offers identical electrical performance with a push-pull output instead of open-drain.
