Description

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.

AS1706 have superb total harmonic distortion (THD) at high-power output and excellent power supply rejection with 4- and 8-loads.

Integrated over-temperature and over-current protection circuitry switch the devices off in case of an output short-circuit. A digital input allows AS1706 to automatically switch into shutdown mode. Click- and popsuppression circuitry reduces audible clicks and pops during power-up and shutdown. The gain (AV) of AS1706 is controlled using external resistors.

The AS1701/AS1706 are available in an 8-pin MSOP package.
