NS4890C Description:
The NS4890C is a Class AB bridge output audio power amplifier. Its application circuit is simple and only a few peripheral devices are needed. The output does not require external coupling capacitors or up-lift capacitors and buffering networks, making it more suitable for portable systems.
The NS4890C can reduce power consumption by entering a low-power shutdown mode via the SD control pin. The voltage gain of the amplifier can be adjusted by configuring the peripheral resistance for easy application.
The NS4890C is available in an MSOP8 package with a rated operating temperature range of -40 ° C to 85 ° C.
