Description
The MD4123 is a 3W high efficiency filterless mono class-D audio power amplifier in a SOP8 package,it has high PSRR and differential input that eliminate noise and RF rectification.
Features
- like 90% efficiency and small PCB area make the MD4123 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 MD4123 features short circuit protection and OTP(over temperature protection) thermal shutdown and UVLO(under voltage lockout). The MD4123 is available in SOP-8 package. Block Diagram
