Overview
The MAX9101ESA+ is a micropower analog comparator from Analog Devices, designed for single-supply operation between 1.0V and 5.5V. It features an open-drain output stage suitable for mixed-voltage designs. Key electrical parameters include a quiescent supply current of 5μA to 8μA, propagation delay under 4μs, and input offset voltage up to ±20mV across the temperature range. The device operates within -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
- Open-drain output stage facilitates mixed-voltage logic interfacing
- Wide input common-mode range extending to the negative rail
- No output phase reversal for overdriven inputs
Applications
- Single-Cell Systems
- Battery-Powered Instrumentation
- Portable Electronic Equipment
- Logic-Level Translation
Procurement Notes
Verify the specific suffix against official documentation to confirm lead-free status and RoHS compliance. Confirm package type matches design requirements. Check availability as distribution may vary by region. Ensure operating conditions align with datasheet limits.
Selection Notes
Select this component when low quiescent current is critical for battery life. The open-drain output requires an external pull-up resistor. Verify that the required propagation delay fits the application timing constraints. Consider the MAX9100 if push-pull output is preferred instead of open-drain.
Part Context
This part belongs to the MAX9100/MAX9101 family of micropower comparators. These devices are engineered for ultra-low voltage applications, offering high efficiency in portable electronics. The family includes variants with different output stages to suit various system architectures.
Replacement Considerations
The MAX9100 serves as a functional alternative within the same family, differing primarily in its push-pull CMOS output stage compared to the MAX9101's open-drain configuration. Both share identical electrical characteristics regarding speed and power consumption.
