MOTOROLA ANALOG IC DEVICE DATA
The MC34119 is a low power audio amplifier intergrated 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. Open
loop gain is 80 dB, and the closed loop gain is set with two external resistors.
A Chip Disable pin permits powering down and/or muting the input signal.
The MC34119 is available in standard 8–pin DIP, SOIC package, and
TSSOP package.
