Overview
The MAX9108EUD+ is a quad, high-speed, low-power voltage comparator designed for single +5V supply systems. It features a 25ns propagation delay with 10mV input overdrive and consumes only 1.75mW per comparator. The device offers TTL-compatible outputs without external pullups and incorporates internal hysteresis for clean switching. It operates within a wide common-mode range extending from 200mV below ground to 1.5V below the positive rail. The component is housed in a 14-pin TSSOP package and supports an operating temperature range of -40°C to +85°C.
Feature Summary
- TTL-compatible outputs eliminate the need for external pullup circuitry
- Internal hysteresis ensures clean output switching with slow-moving signals
- Wide input common-mode range includes ground potential
Applications
- Battery powered systems
- A/D converters
- Line receivers
- Threshold detectors/discriminators
- Sampling circuits
- Zero-crossing detectors
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as supply may be restricted. Ensure the design utilizes a low-inductance ground plane and proper decoupling near the VCC pin to maintain signal integrity at high speeds.
Selection Notes
Select this component when a quad comparator configuration is required with TTL logic compatibility. It serves as a direct upgrade for legacy MAX908 designs, offering improved speed and lower power consumption. Consider the 14-pin TSSOP footprint constraints during PCB layout planning.
Part Context
This part belongs to the MAX910x family of comparators, which also includes dual (MAX9107) and single (MAX9109) channel variants. The MAX9108 specifically provides four independent channels in a compact surface-mount package. It replaces older industry-standard parts like the MAX908 while maintaining similar functional characteristics with enhanced performance metrics.
Replacement Considerations
The MAX9108EUD+ is explicitly documented as a higher-speed, lower-power, and lower-cost upgrade to the MAX908.
