深圳市纳芯威科技有限公司 SHENZHENNSIWAYTECHNOLOGY CO.,LTD NS4890C 2.4W Mono Class AB audio amplifier NS4890C Jun.2022V1.0 1 Features - Voltage range:3.0V-5.0V - 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 shutdown mode. - Stable unity gain. - External feedback resistor and input resistor, adjustable gain. - MSOP8 package. 2 Application - Smart wear - Automobile data recorder 4 Typical application circuit 3 Description 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. 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℃. 2022Copyright © Nsiway Technology 深圳市纳芯威科技有限公司 SHENZHENNSIWAYTECHNOLOGY CO.,LTD 5 Pin configuration The pin diagram of MSOP8 is shown below.
