NJU7870 Series
Amplifier for resolver excitation
Description
NJU7870 is an IC with integrated resolver excitation function. It has a built-in 2-channel excitation circuit for differential voltage input and differential current output. It is possible to control each circuit from the external input, and combine with various resolver systems such as 1-phase excitation or 2-phase excitation. In addition, the NJU7870 achieves high precision performance matching for each phase that has been difficult to achieve with a discrete configuration. The NJU7870 adopts the small package SSOP16-B3, and the external parts are only the capacitor connected to the power supply. It contributes to a significant reduction in mounting area compared with the conventional discrete circuit configuration.
