SA9258

SA9258 4-CH BTL DRIVER FOR CD PLAYER WITH 5V OUTPUT VOLTAGE DESCRIPTION The SA9258, 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.
