APPLICATIONS
The ADCMP350/ADCMP352/ADCMP354/ADCMP356 parts are comparator and reference circuits suitable for use in general-purpose applications. The high voltage input and output structures will 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.

This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 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.
