HT82V73A - Holtek Semiconductor

HT82V73A 1500mW Audio Power Amp

The HT82V73A is an integrated class AB mono speaker driver contained in an SOP 8-pin package. The device is capable of delivering 1500mW of output power into an 8Ω load with less than 10% (THD+N) distortion from a 5V power supply. When in the shutdown mode the very low standby current is an important feature for a wide range of battery powered audio applicat.
