Overview
The MAX903CSA+ is a high-speed, low-power single voltage comparator featuring differential analog inputs and TTL-logic outputs with active internal pull-ups. It operates from separate analog and digital supplies or a single combined supply. The device includes an independent TTL-compatible latch input to hold output states. Typical propagation delay is 8ns at 5mV overdrive. Power consumption is 18mW per comparator at +5V. Input common-mode range includes the negative rail for ground sensing.
Feature Summary
- Features fast propagation delay of 8ns typical at 5mV overdrive
- Includes independent TTL-compatible latch inputs to hold output states
- Supports flexible analog supply ranging from +5V to +10V or ±5V
- Analog input common-mode range includes the negative supply rail
Applications
- High-speed A/D converters
- Sampling circuits
- Line receivers
- Voltage-to-frequency (V/F) converters
- Data-discrimination applications
Procurement Notes
Verify component authenticity through authorized distributors or manufacturer channels. Confirm package integrity and pin alignment against the 8-SOIC specification. Review datasheet revisions for updates on electrical characteristics. Ensure design compliance with absolute maximum ratings to prevent damage. Validate supply voltage configurations match application requirements before integration.
Selection Notes
Select this comparator for designs requiring fast response times and latch functionality. Consider power supply flexibility when choosing between single or split rails. Evaluate thermal dissipation limits under full operating conditions. Compare performance metrics against newer alternatives if lower power consumption is critical. Verify compatibility with downstream TTL logic levels for signal interfacing.
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 series offers varying channel counts and latch options. The MAX903 specifically provides a single comparator with latch capability in an 8-pin package. It is designed for applications demanding rapid signal discrimination and state holding.
Replacement Considerations
The non-plus version MAX903CSA is obsolete. Direct replacement is the MAX903CSA+. For newer designs with half the power dissipation, consider the MAX9201/MAX9202/MAX9203 series which are pin-for-pin compatible.
