Overview
The MAX903ESA+ is a high-speed, low-power single voltage comparator featuring differential analog inputs and TTL-logic outputs with active internal pull-ups. It includes independent TTL-compatible latch inputs to hold output states when driven low. The device supports separate analog and digital power supplies or a single combined supply, with an analog input common-mode range that includes the negative rail for ground sensing. Typical propagation delay is 8ns at 5mV overdrive, and power consumption is 18mW per comparator at +5V.
Feature Summary
- Features fast propagation delay ideal for high-speed data discrimination applications
- Includes independent TTL-compatible latch inputs to capture and hold comparator output states
- Supports flexible analog supply ranging from +5V to +10V or ±5V with separate digital supply
- Analog input common-mode range extends to the negative supply rail
Applications
- High-speed A/D converters
- Line receivers
- Voltage-to-frequency (V/F) converters
- Threshold detectors
- Input trigger circuitry
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix indicates lead-free compliance and RoHS status. Check for Not Recommended for New Designs status in current documentation. Ensure the package matches the required SOIC footprint and pin configuration for your design.
Selection Notes
Select this part for applications requiring fast response times and latch functionality. It is suitable for designs needing separate analog and digital grounds to isolate noise. Consider the MAX920x series for newer designs requiring similar speed with lower power dissipation. Ensure supply voltages match the specified ranges for optimal performance.
Part Context
The MAX903 is part of the MAX900–MAX903 family of high-speed, low-power voltage comparators manufactured by Maxim Integrated, now part of Analog Devices Inc. This family offers single, dual, and quad configurations with varying channel counts. The MAX903 specifically provides a single comparator channel within an 8-pin SOIC package.
Replacement Considerations
The datasheet notes the MAX900 was manufactured using an unavailable process and recommends the MAX9201/MAX9202/MAX9203 as replacements for newer designs due to half the power dissipation. Verify pin compatibility and electrical specifications before substituting.
