The SDA block in the NJW1192 does not hold data. Add external data-delay-circuit of the SDA terminal, in case of not providing a hold time of at least 3nsec for the SDA in the master device. The time-consists of the data-delay-circuit of the SDA terminal are as follows.

Take care that the reduced C1 makes sensitive to ripple of power supply. The input impedance is designed about 48k ohms. The ground line should be inserted between each input lines to avoid cross talk. The wiring patern between these terminals and capacitors should be shortened to prevend the generating of wiring resistance. C5, C21 affect pop-noise when VOL1 or Tone Bass are immediately controlled after powered. Though reducing the capacity of C5, C21may reduce pop-noise, it affects bass frequency characteristic on volume1 attenuation (See Page.22 Voltage Gain vs. Frequency characteristics). Use Pre Charge function for reducing pop-noise.(see Page.14) Loudness frequency can be adjusted with external parts (See Page.7). Especialy, 8 and 25 pins should be kept from large signal lines such as digital signal lines or the other sound signal lines to avoid the digitaly noise or cross talk in Loudness mode. Tone Bass and Treble cut off frequencycan be adjusted with external parts (See Page.7). These pins should be kept from large signal lines such as digital signal lines or the other sound signal lines to avoid the digitaly noise or cross talk in Loudness mode. 12,21 Tone outputs Output impedance is designed about 5 ohms. 13,2 Balance Fader volume inputs Input impedance is designed about 24k ohms. 14,15,18, Balance Fader 19 volume outputs Output impedance is designed about 5 ohms. 16,17 I 2 C control signal ports These terminals should be inserted resistance about 1 ohms between terminal and signal sources to reduce the digitaly noise. These lines should be kept from analog signal lines and or near by the chip to avoid digitaly noises. Inserted ground line between analog line and digital line should be recommended. 7
