| BA5948FP Optical Discs 4-channel BTL driver for CD players BA5948FP BA5948FP is a 4-channel BTL driver for CD players. The adoption of HSOP28 package enables to make sets smaller. This IC incorporates thermal shutdown circuit and mute function with two mute pins. Gain can be controlled by external resistor in driver block. !Applications CD players !Features 1) 4-channel BTL driver 2) Set space saving by adoption of HSOP28 3) Built-in thermal shutdown circuit 4) Gain control by external resistor !External dimensions (Unit : mm) 18.5 0.2 28 15 9.9 0.3 7.5 0.2 1 5.15 0.1 14 2.2 0.1 0.11 0.8 0.35 0.1 0.08 M 16.0 0.2 0.1 S HSOP28 !Absolute maximum ratings (Ta=25C) Parameter Supply voltage Power dissipation Operating temperature range Storage temperature range Symbol Vcc, PVcc1, PVcc2 Limits 18 1700 -35 to +85 -55 to +150 Unit V mW C C Pd Topr Tstg Derating : 13.6mW/ C for operation above Ta=25 C. !Recommended Operating Conditions (Ta=25C) Parameter Supply voltage Symbol Vcc, PVcc1, PVcc2 Min. 4.5 Typ. 8 Max. 14 Unit V 0.5 0.2 0.25 0.1 1/2 BA5948FP Optical Discs !Electrical characteristics (Unless otherwise noted : Ta=25CVCC=8V, BIAS=2.5V, RL=8, Rin=10k) Parameter Current consumption at no signal CH1 output offset voltage Maximum output amplitude Close loop gain CH 2,3,4 output offset voltage Maximum output amplitude Close loop gain Mute OFF voltage Mute ON voltage Symbol ICC VOO1 VOM1 GVC1 VOO2 VOM2 GVC2 VMTOFF VMTON Min. - -50 5.1 12.5 -50 4.0 12.5 - 2.0 Typ. 7.5 - 5.6 15.0 - 4.6 15.0 - - Max. 15 50 6.1 17.5 50 5.1 17.5 0.5 - Unit mA mV V dB mV V dB V V Conditions No load !Application Circuit BIAS 10k FOCUS 10k 0.1F Vcc=8V 47F 28 27 26 25 24 23 22 21 20 19 FOCUS COIL TRACKING COIL TRACKING 18 CH4 17 16 15 CH3 N.C.
