UTC2206B

UTC2206B STEREO AUDIO AMPLIFIER DESCRIPTION LI NEAR I NTEGRATED CI RCUI T The UTC2206B is a monolithic integrated consisting of a 2channel poweramplifier. It is designed for portable cassette players and radios. FEATURES * Higher output power Stereo: Po=2.3W(Typ.) at Vcc=9V,RL=4Ω Bridge: Po=4.7W(Typ.) at Vcc=9V,RL=8Ω * Low voltage distortion at high frequency * Small shock noise at the time of ON/OFF due to a built-in muting Circuit. * Closed loop voltage gain fixed 45dB( Bridge: 51dB) but available with external resistor added) HDIP-12 BLOCK DIAGRAM PRE.
