NJU77903 Series : Rail-to-Rail Input/Output Single CMOS Operational Amplifiers

The NJU77903 is a 36V operable Rail-to-Rail input/output CMOS operational amplifier featuring an output current capacity of 200mAPP typ. It is suitable for high voltage and high output current
applications such as drive motors for hybrid and electric vehicles and resolver excitation applications that are angle detection sensors for EPS. In such applications, high output current was supported by configuring the circuit with multiple parts such as operational amplifiers and transistors, which led to complicated circuit design and larger ECU.By using the NJU77903, it contributes to simplification of design and reduction in size and weight of the mounting board and ECU.

Ideal for high-voltage and high-output current applications such as resolver excitation
