BL8602 Low Power Audio Amplifier
DESCRIPTION
The BL8602 is a low power audio
amplifier integrated circuit
intended(primarily) for telephone
applications, such as in speakerphones.
It provides
differential speaker outputs to
maximize output swing at low supply
voltages(2.0 V minimum).Coupling
capacitors to the speaker are not
required. The gain of this amplifier is
controlled easily by two external
resistors.
FEATURES
* Wide operating supply voltage:
Vcc=2V~16V
* Low quiescent supply current(Icc=2.2mA,typ)
* Medium output power(Po=250mW at Vcc=6V, R_L=32ohm,THD≤10%)
* Load impedance range : 8~100ohm
* Mute function (Icc=55uA, typ)
* Minimum number of external parts required
* Low distortion
