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.
