DESCRIPTION

· NJU7870 is an IC with integrated resolver excitation function, featuring a built-in 2-channel excitation circuit for differential voltage input and differential current output.

· It supports external control for each circuit and can be integrated with various resolver systems, including 1-phase and 2-phase excitation.

· The IC ensures high precision performance matching for each phase, which is challenging with discrete configurations.

· It comes in a compact SSOP16-B3 package, requiring only a power supply capacitor, significantly reducing the mounting area compared to traditional discrete circuits.
