Notes on Application Board’s Pattern Design • For increasing stability, the connected line of VCC and OUTGND is better to be made wider and lower impedance. • For increasing stability, it is better to place the capacitor between VCC and GND (0.1 µF) close to IC. • It is better to place the grounding of resistor (Rg), between input line and ground, close to INGND (Pin 12) because if OUTGND is connected to the line between Rg and INGND, THD will become worse due to current from OUTGND. 0.1 µF VCC 6 3 1 4 5 Rg 12 Figure 1 Notes on Application Board’s Pattern Design 2. How to Reduce the Popping Noise by Muting Circuit At normal operating circuit, Muting circuit operates at high speed under 1 µs. In case popping noise becomes a problem, it is possible to reduce the popping noise by connecting capacitor, which determines the switching time constant, between pin 10 and GND. (Following figure 2) We recommend value of capacitor greater then 1 µF. Also transitional popping noise can be reduced sharply by muting before VCC and Standby are ON/OFF. 5V 0V 7.5 kΩ 10 4.7 µF Muting control Figure 2 How to use Muting Circuit Table 1 Muting ON/OFF Time C (µ µF) ON Time OFF Time nothing under 1 µs under 1 µs 0.47 2 ms 2 ms 4.7 19 ms 19 ms Rev.2, Jul. 1999, page 7 of 15 HA13158A Characteristic Curves Quiescent current vs. Supply Voltage Quiescent current IQ (mA) 400 RL = ∞ 300 200 100 0 0 8 10 12 14 16 18 20 18 20 Supply Voltage VCC (V) Output Power vs. Supply Voltage Output Power Po, Pomax (W) 60 RL = 4 Ω, f = 1 kHz, 4ch operation 50 s) m n 40 ax i (V = 4 Vr m Po 30 20 D (TH Po ) 0% =1 10 0 0 8 10 12 14 16 Supply Voltage VCC (V) Rev.2, Jul. 1999, page 8 of 15 HA13158A Total Harmonic Distortion vs. Frequency Total Harmonic Distortion THD (%) 5 VCC = 13.2 V, RL = 4 Ω, 80 kHz L.P.F ON Po = 1.5 W Po = 8 W 2 1 0.5 0.2 0.1 0.05 0.02 0.01 20 50 100 200 500 1k 2k 5k 10k 20k Frequency f (Hz) Total Harmonic Distortion vs. Output Power 10 VCC = 13.2 V, RL = 4 Ω, 80 kHz L.P.F ON Total Harmonic Distortion THD (%) 5 2 f = 100 Hz f = 1 kHz f = 10 kHz 1 0.5 0.2 0.1 0.05 0.02 0.01 0.01 0.02 0.05 0.1 0.2 0.5 1 2 5 10 20 30 Output Power Po (W) Rev.2, Jul. 1999, page 9 of 15 HA13158A Crosstalk vs. Frequency (1) 80 70 Crosstalk CT (dB) 60 50 40 30 20 10 0 20 VCC = 13.2 V, Vout = 0 dBm, 80 kHz L.P.F, Input Ch1 Ch2 Ch3 Ch4 50 100 200 500 1k 2k 5k 10k 20k 5k 10k 20k Frequency f (Hz) Crosstalk vs. Frequency (2) 80 70 Crosstalk CT (dB) 60 50 40 30 20 10 0 20 VCC = 13.2 V, Vout = 0 dBm, 80 kHz L.P.F, Input Ch2 Ch1 Ch3 Ch4 50 100 200 500 1k 2k Frequency f (Hz) Rev.2, Jul. 1999, page 10 of 15 HA13158A Crosstalk vs. Frequency (3) 80 70 Crosstalk CT (dB) 60 50 40 30 20 10 0 20 VCC = 13.2 V, Vout = 0 dBm, 80 kHz L.P.F, Input Ch3 Ch1 Ch2 Ch4 50 100 200 500 1k 2k 5k 10k 20k 5k 10k 20k Frequency f (Hz) Crosstalk vs. Frequency (4) 80 70 Crosstalk CT (dB) 60 50 40 30 20 10 0 20 VCC = 13.2 V, Vout = 0 dBm, 80 kHz L.P.F, Input Ch4 Ch1 Ch2 Ch3 50 100 200 500 1k 2k Frequency f (Hz) Rev.2, Jul. 1999, page 11 of 15 HA13158A Supply Voltage Rejection Ratio vs. Frequency Supply Voltage Rejection Ratio SVR (dB) 80 70 60 50 40 30 20 10 VCC = 13.2 V, RL = 4 Ω, Vripple = 0 dBm, 80 kHz L.P.F ON Ch1 Ch2 Ch3 Ch4 0 20 50 100 200 500 1k 2k 5k 10k 20k Frequency f (Hz) Wide Band Noise vs. Signal Source Resistance 5 Wide Band Noise WBN (mV) 2 VCC = 13.2 V, RL = 4 Ω, Vin = 0 1 0.5 0.2 Mute OFF (Ch1–Ch4) 0.1 Mute ON (Ch1–Ch4) 0.05 0.02 0.01 20 50 100 200 500 1k 2k 5k 10k 20k Signal Source Resistance Rg (Ω) Rev.2, Jul. 1999, page 12 of 15 50k HA13158A Power Dissipation vs. Output Power 100 RL = 4 Ω, f = 1 kHz, 1ch operation VCC = 13.2 V VCC = 14.4 V VCC = 16 V Power Dissipation PT (W) 50 20 10 5 2 1 0.02 0.05 0.1 0.2 0.5 1 2 5 10 20 30 Output Power Po (W) Power Dissipation vs. Frequency Power Dissipation PT (W) 15 10 5 VCC = 13.2 V, RL = 4 Ω, Po = 10 W, 1ch operation 0 20 50 100 200 500 1k 2k 5k 10k 20k Frequency f (Hz) Rev.2, Jul. 1999, page 13 of 15 HA13158A Package Dimensions Unit: mm 30.18 ± 0.25 2.79 0.05 1.55 +– 0.1 2 – R1.84 ± 0.19 23 0.70 +0.09 –0.1 0.25 M 27.94 1.27 0.06 0.40 +– 0.04 5.08 4.29 Hitachi Code JEDEC EIAJ Weight (reference value) Rev.2, Jul. 1999, page 14 of 15 4.14 ± 0.33 1 17.78 ± 0.25 10.70 ± 0.12 3.80 ± 0.05 17.50 ± 0.13 4.32 ± 0.05 1.12 4.50 ± 0.12 φ 3.80 ± 0.05 19.81 SP-23TE Conforms — 8.5 g HA13158A Disclaimer 1.
