Overview
SA1469PH 4-CH BTL DRIVER FOR CD PLAYER WITH 3.
3V OUTPUT VOLTAGE DESCRIPTION The SA1469PH, an IC for CD players, has a 4-channel BTL driver, 3.
3V regulator (attached PNP transistor required), standard operational amplifier, and internal reset output linked to an internal thermal shutdown circuit.
The driver has gain adjustment input pins for each channel, allowing gain to be set to the desired value.
Also, the internal level shift circuit helps reduce the number of attached components.
