1.6W Audio Power Amplifiers

The AS1701 and AS1706 are 1.6W bridged Audio power Amplifiers that provide excellent circuit reliability, providing a very low-cost solution by eliminating external components when used with 2.7 to 5.5V-powered circuits. The devices have superb total harmonic distortion (THD) at highpower output and excellent power supply rejection with 4- and 8Ohm-loads. Integrated over-temperature and over-current protection circuitry Switch the devices off in case of an output short-circuit. A digital input allows the devices to automatically Switch into shutdown mode. Click- and pop suppression circuitry reduces audible clicks and pops during power-up and shutdown. The gain (AV) of the devices is controlled using external resistors. The AS1701 AS1706 are pin compatible with the LM4891 and the MAX9716. The AS1701 AS1706 are available in an 8-pin MSOP package.
