SL34119

Low Power Audio Amplifier

The SL34119 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 SL34119 is

available in a standard 8 pin DIP or a surface mount package.

Wide Operating Supply Voltage Range (2-16 Volts) - Allows

Telephone Line Powered Applications

Low Quiescent Supply Current for Battery Powered Applications

Chip Disable Input to Power Down the IC

Low Power Down Quiescent Current

Drives a Wide Range of Speaker Loads (8-100W)

Output Power Exceeds 250 mW with 32W Speaker

Low Total Harmonic Distortion

Gain Adjustable from <0 dB to >46 dB for Voice Band

Requires Few External Components
