SGM4890 Datasheet | SG Micro

DESCRIPTION The SGM4890 is a fully-integrated audio power amplifier which operates from 2.5V to 5.5V supply voltage. It can deliver 1.1W into an 8Ω BTL load from 5V supply at THD+N = 1%. It is designed for portable application that needs low-ponent count. The SGM4890 has a low power consumption shutdown mode and thermal shutdown protection. The SGM4890 is applied to low power portable systems. Output coupling capacitors or bootstrap capacitors are not needed. The SGM4890 provides an externally controlled gain (with resistors), as well as an externally controlled turn-on time (with the bypass capacitor) for maximum flexibility. The SGM4890 is available in a Green MSOP-8 package. It operates over an ambient temperature range of -40℃ to +85℃.
