19-0157; Rev 2; 8/03 Single/Dual, Ultra-Fast, Low-PowerPrecision TTL ComparatorsMAX912/MAX913General DescriptionFeatures The MAX913 single and MAX912 dual, high-speed, ♦ Ultra Fast (10ns) low-power comparators have differential inputs and complementary TTL outputs. Fast propagation delay ♦ Single +5V or Dual ±5V Supply Operation (10ns, typ), extremely low supply current, and a wide ♦ Input Range Extends Below Negative Supply common-mode input range that includes the negative rail make the MAX912/MAX913 ideal for low-power, ♦ Low Power: 6mA (+5V) Per Comparator 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. The MAX912/MAX913 can be powered from a single ♦ Low Offset Voltage: 0.8mV +5V supply or a ±5V split supply. The MAX913 is an ♦ Now Available in a Small µMAX Package improved plug-in replacement for the LT1016. It pro- vides significantly wider input voltage range and equiv- alent speed at a fraction of the power. The MAX912 Ordering Information dual comparator has equal performance to the MAX913 and includes independent latch controls.
