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. www.DataSheet4U.com
FEATURES
* 1-phase, full-wave, linear DC motor driver * Gain is adjustable with an attached resistor. * Internal standard operational amplifier. * Internal 3.3V regulator. (required attached PNP transistor) * Internal thermal shutdown circuit with hysteresis capabilities.
