Overview
The MAX9108ESD+ is a quad, high-speed, low-power voltage comparator designed for single +5V supply systems. It features a propagation delay of 25ns with 10mV input overdrive and consumes only 350µA (1.75mW) per comparator. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to +85°C. It incorporates internal hysteresis of 2mV and TTL-compatible outputs.
Feature Summary
- Incorporates internal hysteresis to ensure clean output switching even when driven by slow-moving input signals.
- Features TTL-compatible outputs that require no external pullup circuitry.
- Provides a wide input common-mode range extending from 200mV below ground to within 1.5V of the positive supply rail.
Applications
- Battery powered systems
- A/D converters
- Line receivers
- Threshold detectors/discriminators
- Sampling circuits
Procurement Notes
Verify the specific package code S14-1 corresponds to the 14-pin SOIC configuration. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the ordering suffix matches the required tape-and-reel or tube packaging format. Cross-reference the datasheet revision date to confirm technical specifications have not changed.
Selection Notes
Select this component for applications requiring fast response times with minimal power consumption in single-supply environments. The quad configuration allows multiple comparisons in a compact footprint. Verify that the input signal levels remain within the specified common-mode range to maintain accurate threshold detection.
Part Context
This part belongs to the MAX910x family, which includes dual (MAX9107), quad (MAX9108), and single (MAX9109) comparators. The MAX9108 specifically provides four independent channels in a 14-pin package. It serves as a higher-speed, lower-power upgrade to industry-standard comparators like the MAX908.
Replacement Considerations
The MAX908ESD+ is a direct functional predecessor offering similar quad-channel performance but with slower speed characteristics. Designers upgrading from older generations should verify timing requirements against the new 25ns specification.
