Low Power Audio Amplifier
The IL34119 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 IL34119 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 (8-100 )
Output Power Exceeds 250 mW with 32 Speaker
Low Total Harmonic Distortion
Gain Adjustable from <0 dB to >46 dB for Voice Band
Requires Few External Components
