Lower Your IQ

Consuming only nanoamps of quiescent current, our nanoPower op amps, comparators and current sense amplifiers enable the longest battery life. They are offered in tiny, space saving packages. This makes our nanoPower amplifiers ideal for small, battery-operated, and low-power devices such as those designed for wearable, portable, IoT, and wireless applications.

nanoPower Op Amps
nanoPower operation amplifiers consume less than a micro amp of supply current. With tiny package options, they offer low voltage operation, rail-to-rail output capabilities, low input bias current, high open loop voltage gain, low input offset voltage and operation over extended temperature ranges (from -40°C up to +125°C).

nanoPower Comparators
nanoPower comparators consume ultra-low supply current. With tiny package options, they offer low-voltage operation, internal precision references, push-pull or open-drain outputs, high RF immunity and operation over extended temperature ranges (from over -40°C up to +125°C).
