Overview
SA1469XH 4-CH BTL DRIVER FOR CD PLAYER WITH 5.
0V OUTPUT VOLTAGE DESCRIPTION The SA1469XH, an IC for CD players, has a 4-channel BTL driver, 5V 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.
FEATURES * 1-phase, full-wave, linear DC motor driver * Gain is adjustable with an attached resistor.
* Internal standard operational amplifier.
* Internal 5V regulator.
(required attached PNP transistor) * Internal thermal shutdown circuit with hysteresis capabilities.
ORDERING INFORMATION Device SA1469XH Package HSOP-28-375-0.
