ADCMP350/ADCMP352/ADCMP354/ADCMP356 are open-drain output comparators and reference circuits suitable for use in general-purpose applications. The high voltage input and output structures will allow voltage detectors, microprocessor systems, computers, battery monitors, intelligent instruments and portable equipment to be applied.
The ADCMP350, ADCMP352, ADCMP354 and ADCMP356 are comparator and reference circuits from Analog Devices. They feature on‑chip 0.6 V references, high‑voltage tolerance up to 22 V on input pins, and low power consumption (10 pA to 15 µA). Their SC70 package makes them suitable for battery‑powered portable equipment and automotive‑grade applications.
Key specifications include a wide operating temperature range (‑40 °C to +125 °C), input voltage range up to 22 V, and fast propagation delay (5 µs). The devices are offered in open‑drain and push‑pull output configurations, with typical output rise/fall times of 30 ns and 45 ns respectively.
