MAX9100ESA

Overview

The MAX9100ESA is a micropower analog comparator from Analog Devices, designed for single-supply operation between 1.0V and 5.5V. It features a push-pull CMOS output stage capable of rail-to-rail swings with up to 5mA drive current. The device consumes 5µA quiescent current at 1.0V supply voltage. Key electrical parameters include a typical propagation delay of 4µs, input offset voltage of ±10mV, and input bias current of ±15nA. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin SO package.

Feature Summary

• Ultra-low voltage operation optimized for single-cell battery-powered systems
• Push-pull CMOS output stage providing rail-to-rail swing and high drive capability
• Wide input common-mode range extending to the negative rail
• No output phase reversal for overdriven inputs

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and lead-free packaging requirements against specific project standards. Check for obsolescence notices as product availability may vary. Ensure proper handling procedures are followed during storage and assembly to maintain device integrity.

Selection Notes

Select this comparator when ultra-low voltage operation down to 1.0V is required. Choose the MAX9100ESA variant specifically for applications needing a push-pull output stage rather than open-drain. Consider its low quiescent current for extended battery life in portable devices. Evaluate the 4µs propagation delay against system timing requirements before finalizing the design.

Part Context

The MAX9100ESA belongs to the MAX9100/MAX9101 family of micropower comparators. This series is engineered for efficiency in portable electronics. The MAX9100 differs from the MAX9101 primarily by its output stage configuration. Both share similar power consumption and input characteristics but serve different interface needs regarding output drive topology.

Replacement Considerations

Direct substitutes include the MAX9101ESA for mixed-voltage designs requiring open-drain outputs. Verify pin compatibility and electrical specifications before swapping components. Ensure the replacement maintains the required push-pull functionality if that is critical to the circuit design.
