MAX912/MAX913 19-0157 Rev 2 8/03 Single/Dual, Ultra-Fast, Low-Power Precision TTL Comparators General Description Features The MAX913 single and MAX912 dual, high-speed, Ultra Fast (10ns) low-power comparators have differential inputs and Single +5V or Dual 5V Supply Operation complementary TTL outputs. Fast propagation delay (10ns, typ), extremely low supply current, and a wide Input Range Extends Below Negative Supply common-mode input range that includes the negative Low Power: 6mA (+5V) Per Comparator rail make the MAX912/MAX913 ideal for low-power, high-speed, single +5V (or 5V) applications such as No Minimum Input Signal Slew-Rate Requirement V/F converters or switching regulators. No Power-Supply Current Spiking The MAX912/MAX913 outputs remain stable through the linear region. This feature eliminates output instabili- Stable in the Linear Region ty common to high-speed comparators when driven Inputs Can Exceed Either Supply with a slow-moving input signal. Low Offset Voltage: 0.8mV The MAX912/MAX913 can be powered from a single +5V supply or a 5V split supply. The MAX913 is an Now Available in a Small MAX Package improved plug-in replacement for the LT1016.

The MAX912 dual comparator has equal performance to the MAX913 and includes independent latch controls.
