GENERAL DESCRIPTION
The ADCMP350/ADCMP354/ADCMP356 are comparator and
reference circuits suitable for use in general-purpose applications.
The high voltage input and output structures 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.
