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

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the

human body and test equipment and can discharge without detection. Although this product features

proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy

electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance

degradation or loss of functionality.
