The ADCMP370/ADCMP371 are general-purpose comparators with low power consumption and low input offset voltage, making them ideal for battery-powered portable devices. The ADCMP371 has a push-pull output stage.
The ADCMP370/ADCMP371 comparators provide rail‑to‑rail input range, low offset voltage, and low bias currents, making them suitable for battery‑powered and portable equipment. The ADCMP370 features an open‑drain output, while the ADCMP371 uses a push‑pull output, both tolerant to up to 22 V on inputs.
Key specifications include a 2.25‑5.5 V operating range, supply current as low as 4 µA, input offset voltage of 9 mV, and various absolute‑maximum ratings. The devices are supplied in a 5‑lead SC70 (KS‑5) package and are listed for a temperature range of –40 °C to +85 °C.
