Overview
The MAX913CSA+T is a single, high-speed, low-power precision TTL comparator manufactured by Analog Devices Inc./Maxim Integrated. It features differential inputs and complementary TTL outputs with a typical propagation delay of 10ns. The device operates from a single +5V or dual ±5V supply, drawing 6mA per comparator at +5V. It offers a wide common-mode input range extending below the negative rail and includes a latch function for output state holding.
Feature Summary
- Ultra-fast propagation delay of 10ns typical
- Low power consumption of 6mA per comparator
- Stable operation in the linear region without oscillation
- Input voltage range extends below the negative supply rail
Applications
- Zero-Crossing Detectors
- Ethernet Line Receivers
- Switching Regulators
- High-Speed Sampling Circuits
- Fast Pulse Width/Height Discriminators
Procurement Notes
Verify the specific suffix CSA+T against the manufacturer's current ordering information to confirm package type (SOIC-8) and temperature range (0°C to +70°C). Ensure compatibility with existing board layouts and supply voltages (+5V single or ±5V split). Confirm RoHS compliance status as indicated in the latest datasheet revision.
Selection Notes
Select this component when high speed and low power are critical requirements. It serves as an improved plug-in replacement for the LT1016, offering wider input voltage range and equivalent speed at lower power. Consider the integrated latch feature if signal stability during transitions is required. Verify that the SOIC-8 package fits the design constraints.
Part Context
The MAX913 is part of the MAX912/MAX913 family of ultra-fast, low-power precision TTL comparators. The MAX912 is the dual version with independent latch controls. These devices are designed for applications requiring fast response times and minimal power dissipation, such as V/F converters and switching regulators.
Replacement Considerations
The MAX913 is explicitly documented as an improved plug-in replacement for the LT1016. When substituting, verify that the input voltage range and supply voltage requirements of the original circuit are compatible with the MAX913's specifications.
FAQ
Does the MAX913 require hysteresis to prevent oscillation?
No, the MAX913 is designed to remain stable through the linear region and does not require hysteresis, which helps maintain high resolution.
What is the maximum clock rate for the MAX913?
The maximum clock and signal rate is 70MHz based on rise/fall time with 5mV overdrive, or 85MHz with 20mV overdrive.
