NS4890C Overview
NS4890C is a class AB bridge output audio amplifier. Its application circuit is simple and only a few peripheral devices are needed.The output does not require external coupling capacitors or lifting capacitors and buffering networks,it is more suitable for portable systems. NS4890C can reduce power consumption by controlling the SD pin to enter low power shutdown mode.
