MC34119-D08-T

Manufacturer Part Number
MC34119-D08-T
Description
LOW POWER AUDIO AMPLIFIER
Manufacturer
UTC [Unisonic Technologies]
Datasheet
MC34119
LOW POWER AUDIO
AMPLIFIER
the telephone applications, such as in speakerphones. It provides
differential speaker outputs to maximize output swing at low supply
voltages. Coupling capacitor to the speaker is not required. Open
loop gain is 80dB, and the closed loop gain is set with two external
resistors. The Mute pin permits powering down and/or muting the
input signal.
*Wide operating supply voltage: V
*Low quiescent supply current (I
*Medium output power (P
*Load impedance range (8 to 100ohm)
*Low distortion
*Mute function (I
*Minimum number of external parts required

... MC34119 PIN CONFIGURATION MUTE PIN NAME This pin can be used to power down the IC to converse power, or for muting, or both. When at a logic “LOW” (less than 0.8V), the IC is enabled for normal 1 Mute operation. When at a logic “HIGH” (2V to Vcc), the IC is disabled. If Mute is open, that is equivalent to a logic “ ...
