ECL4871-3W Audio Power Amplifier With Shutdown Mode

General Description

The ECL4871 is a bridge-connected audio power amplifier capable of delivering typically 3W of continuous average power to an 3Ω load with10% (THD) from a 5V power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. Since the ECL4871 does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is optionally suited for low-power portable systems. The ECL4871 features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. The unity-gain stable ECL4871 can be configured by external gain-setting resistors.
