com UTC MC3419 LINEAR INTEGRATED CIRCUIT LOW POWER AUDIO AMPLIFIER DESCRIPTION The UTC MC3419 is a low power audio amplifier integrated circuit, intended for 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.
A chips disable pin permits powering down and/or muting the input signal.
SOP-8 DIP-8 FEATURES *Wide operating supply voltage: Vcc=2V~16V *Low quiescent supply current (Icc=2.
7mA, typ) *Medium output power (Po=250mW at Vcc=6V, RL=32ohm, THD=1...
