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.
