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
