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. 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.
