The ADCMP670 is a dual low power 1.5% comparator with a 400mV reference voltage. It features a 400mV ± 1.5% threshold, a supply range of 1.7V to 5.5V, low quiescent current, an input range that includes ground, open-drain outputs, and is suitable for applications such as Li-Ion monitoring, portable devices, handheld instruments, window comparators, LED/relay driving, optoisolator driving, and control systems.
The ADCMP670 combines two low‑power, high‑accuracy comparators and an internal 400 mV reference in a 6‑lead TSOT package. It is suited for Li‑ion monitoring, portable instruments, window‑comparator functions, LED/relay driving and other low‑voltage control applications.
Key specifications include a supply range of 1.7 V to 5.5 V, typical quiescent current of 6.5 µA, input bias current up to 10 nA, hysteresis around 8.9 mV, and open‑drain outputs capable of sinking >5 mA. The device operates from –40 °C to +125 °C and is supplied in a 1 mm low‑profile TSOT package.
