General Description
The MAX913 single and MAX912 dual high-speed, low-power comparators have differential inputs and complementary TTL outputs. Fast propagation delay (10ns typ), extremely low supply current, and a wide common-mode input range that includes the negative rail make the MAX912/MAX913 ideal for low-power, high-speed, single +5V (or ±5V) applications such as V/F converters or switching regulators.

Features
♦ Ultra Fast (10ns)
♦ Single +5V or Dual ±5V Supply Operation
♦ Input Range Extends Below Negative Supply
♦ Low Power: 6mA (+5V) Per Comparator
♦ No Minimum Input Signal Slew-Rate Requirement
♦ No Power-Supply Current Spiking
♦ Stable in the Linear Region
♦ Inputs Can Exceed Either Supply
♦ Low Offset Voltage: 0.8mV

Applications
    Zero-Crossing Detectors
    Ethernet Line Receivers
    Switching Regulators
    High-Speed Sampling Circuits
    High-Speed Triggers
    Extended Range V/F Converters
    Fast Pulse Width/Height Discriminators
