However, the thermal shutdown circuit is reset automatically if the temperature drops. • Please carefully design the heat radiation especially when you take out high power at high VCC . • Please connect only the ground for the signal input with the signal GND of the amplifier in the previous stage. • Take notice that the ripple rejection ratio is poor in case of headphone use. • Take notice that as to following pins, electric surge voltage is low. At 200 pF, Pin1 = +140 V, Pin9 = +140 V, Pin20 = +130 V, Pin28 = +150 V. • Use a speaker with 8 Ω or more impedance. 7 AN7512SH ICs for Audio Common Use ■ Technical Data • Main characteristics • PD Ta curve of HSOP056-P-0300A CT f 1.400 1.300 1.257 1.200 90 Mounted on standard board (glass epoxy: 50 × 50 × t0.8 mm3) Rth(j-a) = 79.5°C/W 80 Ch.1 70 1.000 Cross talk CT (dB) Power dissipation PD (W) 1.100 0.900 0.800 0.700 0.690 0.600 Independent IC without a heat sink Rth( j-a) = 144.9°C/W 0.500 60 Ch.2 50 40 VCC = 5 V PO = 0.25 W RL = 8 Ω Rg = 10 kΩ VSTB = 5 V Vol. = 1.25 V 30 20 0.400 0.300 10 0.200 0 10 100 1 000 10 000 100 000 0.100 Frequency f (Hz) 0.000 0 50 25 75 100 125 Ambient temperature Ta (°C) ICQ , ISTB VCC 100 f = 1 kHz THD = 10% RL = 8 Ω 400 Hz HPF 30 kHz LPF Both ch. inputs Rg = 10 kΩ VSTB = 5 V Vol. = 1.25 V 5 4 Ch.1, Ch.2 3 2 1 80 7 60 6 50 5 ICQ 40 4 30 3 20 0 0 2 4 6 8 10 12 2 ISTB 14 0 PO , THD VIN 1 10 THD (ch.2, 10 kHz) THD (ch.1, 10 kHz) 1 0.1 THD (ch.1, 100 kHz) THD (ch.2, 100 kHz) THD (ch.2, 1 kHz) 0.01 THD (ch.1, 1 kHz) PO (ch.1, ch.2) 0.001 1 10 100 Input voltage VIN (mV[rms]) 8 6 8 10 12 0.1 0.01 1 000 3.5 14 0 0.9 0.8 3.0 Power consumption PC (W) Both ch. inputs Rg = 10 kΩ VSTB = 5 V Vol. = 1.25 V 4 PC , ICC PO 100 Total harmonic distortion THD (%) Output power PO (W) VCC = 5 V f = 1 kHz RL = 8 Ω 400 Hz HPF 30 kHz LPF 2 1 Supply voltage VCC (V) Supply voltage VCC (V) 10 8 70 10 0 9 ICC (8 Ω) 0.7 2.5 0.6 2.0 0.5 0.4 1.5 PC (8 Ω) 1.0 VCC = 5V f = 1 kHz RL = 8 Ω 400 Hz HPF 30 kHz LPF 0.5 0.0 0.0 0.5 Both ch. inputs Rg = 10 kΩ VSTB = 5 V Vol. = 1.25 V 1.0 Output power (1-ch) PO (W) 0.3 0.2 0.1 0.0 1.5 Supply current ICC (A) Output power PO (W) 6 Quiescent circuit current ICQ (mA) 7 10 RL = 8 Ω Both ch. inputs Rg = 10 kΩ VSTB = 0 V/5 V VMUTE = 0 V 90 Standby current ISTB (µA) PO VCC 8 ICs for Audio Common Use AN7512SH ■ Technical Data (continued) • Main characteristics (continued) GV , PO f THD f 35 1.4 31 1.2 PO (ch.1) 30 1.0 PO (ch.2) 29 0.8 28 VCC = 5 V RL = 8 Ω 400 Hz HPF 30 kHz LPF 26 100 1 000 0.6 0.4 37 36 1.0 0 0.9 10 0.8 0.7 0.6 35 0.5 GV (ch.2) 0.4 33 0.3 THD (ch.2) 32 0.2 GV (ch.1) THD (ch.1) 2 10 100 4 6 8 10 12 14 100 000 Ch.1, Ch.2 30 40 VCC = 5 V PO = 0.25 W f = 1 kHz RL = 8 Ω 400 Hz HPF 30 kHz LPF Rg = 10 kΩ VSTB = 5 V Vol. = 0 V 50 60 70 0.1 80 0.0 90 0.0 0.2 0.4 0.6 0.8 1.0 1.2 1.4 Volume voltage Vol. (V) RR VRIPPLE RR fRIPPLE 80 80 Ch.1 (vol.-max.)
