LA5318V Maximum Output Current Load Test Conditions
Input 1
Input 2
VCC - VEE = 35 V, RX = 8R, C1 to C4 = 10 F, C5 = 33 F, All resistors must be rated 1 W or higher. TR1 to TR4; 2SA984 Rank E or F TR5 to TR9; 2SC2274 Rank E or F Set the output load resistors (R1 to R8) so that currents of 25 to 30 mA maximum (except for the V3 and V4 source sides, which can handle about 60 mA) flow in the sink and source sides when high (on state) levels are input to inputs 1 and 2.
Input 1
Input 2
* VREF control block Determining the TR1 drive current V - VBE - VIN I = CC 11 k + R (VBE 0.7 V) Drive current V - 0.7 - VIN IO 10I = CC x 10 11 k + R Assume that the TR1hFE is 50 for this calculation. Note: Connect INR to VCC when INR and OUTR are not used.
