NS4890C Datasheet | ChipSourceTek

Features 3 NS4890C Description - Voltage range:3.0V-5.0V NS4890C is a class AB bridge output audio - Output power: 1.56W@RL=8Ω/THD+N=10% - Leakage current in shutdown mode:1u A(typical) - The SD pin is used for low level control to enter 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 shutdown mode. - Stable unity gain. - External feedback resistor and input resistor, 技 k adjustable gain. e - MSOP8 package. 2 NS4890C Application 科 T - Smart wear - Automobile data recorder 矽Ch源ip特Source 4 NS4890C Typical application circuit for portable systems. NS4890C can reduce power consumption by controlling the SD pin to enter low power shutdown mode. The voltage gain of the amplifier can be adjusted by configuring the peripheral resistor for easy application. NS4890C is available in MSOP8 package and is rated for operating temperatures ranging from -40℃ to 85℃. TEL: +86-0755-27595155 27595165 FAX: +86-0755-27594792 WEB:Http://.Chip Source Tek.
