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.
