www.DataSheet4U.com AS1701, AS1706 1.6W Audio Power Amplifiers D a ta S he e t 1 General 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 high-power output and excellent power supply rejection with 4- and 8Ω-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 popsuppression 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 available in an 8-pin MSOP package. 2 Key Features ! ! ! ! ! ! ! ! ! ! 2.7 to 5.5V (VDD) Single-Supply Operation Very High PSRR: Greater Than 65dB @ 217Hz THD+Noise: 1.6W into 4Ω at 1% No Output Coupling Capacitors Required External Gain Configuration Capability Low-Power Shutdown Mode: 10nA Click and Pop Suppression Over-Temperature and Over-Current Protection Operating Temperature Range: -40 to +85°C 8-pin MSOP Package 3 Applications The AS1701/AS1706 are ideal as audio front-ends for battery powered audio devices such as MP3 and CD players, mobile phones, PDAs, portable DVD players, and any other hand-held battery-powered device.
