MD4103 Product details

Description

The MD4103 is a W3 high efficiency filterless mono class-D audio power amplifier in a MSOP8 package,and a DFN package that requires only three external components,it has High PSRR and differential input that eliminate noise and RF rectification.

Features

like 90% efficiency and small PCB area make the MD4103 class-D amplifier ideal for cellular handsets. A low noise, filterless PWM architecture eliminates the output filter, reducing external component count, system cost, and simplifying design. The MD4103 features short circuit protection and OTP(over temperature protection) thermal shutdown and UVLO(under voltage lockout). The MD4103 is available in DFN2X2-8L and MSOP-8 package. Block Diagram Features PO at 10% THD+N, VDD = 5V RL = 4 Ω 3.0W (t.
