AS1701数据手册开发板套件编程器的评估板-音频放大器规格书PDF

描述 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.\r
\r
The devices have superb total harmonic distortion (THD) at high-power output and excellent power supply rejection with 4- and 8Ω-loads.\r
\r
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 popsuppression circuitry reduces audible clicks and pops during power-up and shutdown. The gain (AV) of the devices is controlled using external resistors.\r
\r
The AS1701/AS1706 are available in an 8-pin MSOP package.
