GENERAL DESCRIPTION

The ADCMP350/ADCMP352/ADCMP354/ADCMP356 parts

are comparator and reference circuits suitable for use in

general-purpose applications. The high voltage input and

output structures will allow voltages of up to 22 V on the input

of all devices and the output of the open-drain devices. High

performance over the −40°C to +125°C temperature range

makes them suitable for use in automotive and other thermally

harsh applications, while low power consumption and space-

efficient SC70 packaging make them ideal for battery-powered

portable equipment.
