GENERAL DESCRIPTION

The ADCMP350-ADCMP357 are comparator and reference

circuits suitable for use in general purpose applications. High

performance over the -40°C to +125°C temperature range make

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
