Low Power Audio Amplifier
TECHNICAL DATA
IL34119
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.
m• Wide Operating Supply Voltage Range (2-16 Volts) - Allows
Telephone Line Powered Applications
o• Low Quiescent Supply Current for Battery Powered Applications
.c• Chip Disable Input to Power Down the IC
• Low Power Down Quiescent Current
• Drives a Wide Range of Speaker Loads (8-100Ω)
U• Output Power Exceeds 250 mW with 32Ω Speaker
• Low Total Harmonic Distortion
t4• Gain Adjustable from <0 dB to >46 dB for Voice Band
• Requires Few External Components
