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.
