The LM4876 does not require output coupling capacitors, bootstrap capacitors, or • Mobile Phones snubber networks. It is perfectly suited for low-power • Portable Computers portable systems. • Desktop Computers The LM4876 features an active low externally • Low-Voltage Audio Systems controlled, micro-power shutdown mode. Additionally, the LM4876 features an internal thermal shutdown KEY SPECIFICATIONS protection mechanism. For PCB space efficiency, the LM4876 is available in VSSOP and SOIC surface • THD+N at 1kHz for 1W Continuous Average mount packages. Output Power into 8 Ω 0.5% (max) The unity-gain stable LM4876's closed loop gain is • Output Power At 1kHz Into 8 Ω with 10% set using external resistors. THD+N 1.5 W (typ) • Shutdown Current 0.01µA (typ) • Supply Voltage Range 2.0V to 5.5 V Typical Application Figure 1.
