MCZ34119 Datasheet (Freescale Semiconductor)

MCZ34119, Low Power Audio Amplifier

Freescale Semiconductor Technical Data Document Number: MC34119 Rev.

3.0, 12/2006 Low Power Audio Amplifier The 34119 is a low power audio amplifier integrated circuit intended 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.
