TECHNICAL DATA

KK34119

Low Power Audio Amplifier

The KK34119 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 volts 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 KK34119 is available in a standard 8

pin DIP or a surface mount package.
