During the ON/OFF transitions is recommend to respect the following conditions. - At the turn-on, the transition mute - play must be made when the SVR pin is higher than 2.5V - At the turn-off, the TDA7496 must be brought to mute from the play condition when the SVR pin is higher than 2.5V. 5/10 TDA7496S Output DC Voltage vs. Supply Voltage Quiescent Current vs. Supply Voltage 32 Vodc (V) Iq (mA) 30 Vi=0 28 26 24 22 20 18 16 10 12 14 16 18 20 22 24 26 28 30 32 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 10 Vi=0 12 14 16 Output DC Offset vs. Supply Voltage 300 18 20 22 24 26 28 30 32 Supply Voltage (V) Supply Voltage (V) Output Power vs. Supply Voltage Vodc-Vsvr (V) 10 280 Ouput Power (W) 9 260 8 Vi=0 240 7 220 6 200 5 180 4 160 3 140 2 120 1 100 10 12 14 16 18 20 22 24 26 28 30 32 Rl=8 Ohm F= 1 KHz THD=10 % THD=1 % 0 10 12 14 16 Supply Voltage (V) Output Power vs. Supply Voltage 10 24 26 Vs=22V Rl=8 Ohm 1 F=15 KHz 0.1 THD=1 % F=1 KHz 10.5 11 11.5 12 12.5 Supply Voltage (V) 6/10 22 Distortion (%) THD=10 % Rl=4 Ohm F= 1 KHz 20 Distortion vs. Output Power Ouput Power (W) 3.6 3.4 3.2 3 2.8 2.6 2.4 2.2 2 1.8 1.6 1.4 1.2 1 0.8 0.6 0.4 0.2 0 10 18 Supply Voltage (V) 13 13.5 14 0.01 0 0.5 1 1.5 2 2.5 3 3.5 Output Power (W) 4 4.5 5 5.5 TDA7496S Distortion vs. Output Power 10 Closed Loop Gain vs. Frequency Distortion (%) 32 Closed Loop Gain (dB) 31 30 F=15 KHz 29 1 28 Rl=8 Ohm Pout=0.5W Cin=470nF Cout =1000uF Csvr=470 uF 27 Vs=12V Rl=4 Ohm 26 25 0.1 24 23 F=1 KHz 22 21 0.01 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1 1.1 1.2 1.3 1.4 1.5 1.6 1.7 1.8 1.9 2 2.1 20 0.02 0.2 Output Power (W) St-By Attenuation vs. Vpin 9 20 10 0 -10 -20 -30 -40 -50 -60 -70 -80 -90 -100 -110 -120 -130 -140 20 10 0 -10 -20 -30 -40 Rl=8 Ohm 0 dB @ Pout=1W 0.5 1 1.5 -50 -60 -70 -80 -90 -100 -110 -120 2 2.5 20 Mute Attenuation vs. Vpin 10 Stand-by Attenuation (dB) 0 2 Frequency (KHz) 3 3.5 4 4.5 5 Mute Attenuation (dB) Rl=8 Ohm 0 dB @ Pout=1W 0 0.4 0.8 1.2 1.6 2 2.4 2.8 3.2 3.6 4 4.4 4.8 5.2 Vpin # 10 (V) Vpin # 9 (V) PINS DESCRIPTION PIN: SVR VS VS VS OUT L + - 20K 6K 1K 20K 6K 1K 30K SVR 30K - OUT R + 100µA D97AU585A 7/10 TDA7496S PIN: MUTE PINS: INL, INR VS VS 500µA 6K MUTE 200 10K INn 50µA 30K D97AU592 D97AU589 SVR PINS: PW-GND, S-GND PINS: OUT R, OUT L VS VS OUT GND D97AU593 D97AU588 PIN: STBY VS 10µA STBY 200 65K D97AU594 8/10 TDA7496S mm DIM.
