Description

GAUGE PLANE

The SPW34119D is a low power audio amplifier integrated circuit

intended (primarily) for telephone applications, such as in speaker-

phones. It provides differential speaker outputs to max. output

swing at low supply voltages (2V min.). Coupling capacitors to the

speaker are not required. Open loop gain is 80dB, and the closed

loop gain is set with two external resistors. A Chip Disable pin

permits powering down and/or muting the input signal.
