Description
The RRA79001 (single) and RRA79002 (dual) are low-power operational amplifiers designed for modern, space-conscious electronics. With rail-to-rail input and output swing, these op amps deliver exceptional performance in tight quarters, making them ideal for smoke detectors, wearable tech, and compact appliances where low-voltage operation and robust capacitive-load driving are essential.
