Nisshinbo Micro Devices NJU77903
Operational amplifier with high output current and Rail-to-Rail input/output
The NJU77903 is CMOS operational amplifier combines full swing input and output with operating up to 36V. It outputs typically up to 200mA of peak-to-peak current to drive low resistance load including inductance load such as Angle resolver, Lineout cable and Piezo actuator. NJU77903 includes integrated EMI filter to reduce malfunctions caused by RF noises from mobile phones and other wireless devices.
