File name LA4485.pdf Ordering number: EN3680C Monolithic Linear IC LA4485 5 W, Two-channel Power Amplifier with Very Few External Parts Overview The LA4485 is a 5 W, two-channel power amplifier IC that requires a minimum of external parts, making it ideal for radio cassette players and car stereo equipment. The LA4485 eliminates the need for bootstrap capacitors, negative feedback capacitors, and oscillation prevention CR parts, all of which were necessities for power ICs previously. All of these functions are now on chip, keeping the number of external parts to an absolute minimum. The LA4485 is part of the Power (Stylish Power) Series, and supports two modes: dual and BTL. Package Dimensions unit : mm 3107-SIP13H [LA4485] Features . 5 W × 2 output power in dual mode, and 15 W in BTL mode . Minimum external parts for the Power Series count: in dual . 4 or 5 partscircuits mode; 3 or 4 parts in BTL mode Protection . . . . Overvoltage protection Thermal protection DC output short-circuit protection (to VCC and to GND) Circuitry designed to handle +VCC applied to the outputs Pop noise reduction Standby switch Muting function SANYO : SIP13H Specifications Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage Surge supply voltage Peak output current Allowable power dissipation Operating temperature Storage temperature Symbol VCC max VCC surge * IO peak Pd max Topr Tstg No signal Based on the JASO standard Per channel With infinite heat sink Conditions Ratings 24 50 3.3 15 30 to +80 40 to +150 Unit V V A W °C °C *: By the type B check point method.
