Description 

SC7069 is a stereo headphone amplifier that eliminates the need for external dc-blocking output capacitors.

 SC7069 features stereo inputs that can be set in either differential or single-ended input. 4 different gain with different built-in resistors reducing external component is selectable. 

SC7069 drives 28mW into 32ohm speakers/headphone from a 3.6V supply. THD+N is 0.01% low. 

SC7069 operates from a single 2.5V to 5.5V supply with 3.6mA of typical supply current. Shutdown mode reduces supply current to less than 1μA. Thermal-overload protection, low voltage malfunction prevention function is integrated in SC7069.

Application 

・Bluetooth headset 

・Smart phone

 ・Portable speaker

 ・Tablet/Notebook
