Elektronische Bauelemente
RoHS Compliant Product
Description
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.
