Cb ; total capacitance of one bus line in pF.
NOTE). Data hold time : tHD:DAT
Please hold the Data Hold Time (tHD:DAT) to 300ns or more to avoid status of unstable at SCL falling edge.
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 300nsec for the SDA in the master device.
The time-consists of the data-delay-circuit of the SDA terminal are as follows.
(a) Low level Æ High level : TLH ≈ RP*CD
(b) High level Æ Low level : THL ≈ RD*CD
In addition, Schottky barrier diode (SBD) influences a Low level at the Acknowledge. Therefore choose the low forward
voltage (Vf) as much as possible.

Pin No. Function Note
2Vref C1 can be adjusted rise and fall time of reference voltage at power on and off. Take care that the reduced C1 makes sensitive to ripple
of power supply.
3-5, 28-31 Inputs The input impedance is designed about 48k ohms.
The ground line should be inserted between each input lines to avoid cross talk.

terminals
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).

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.

Pre Charge* 0 0 0 0 0 0
* Pre Charge : Charge the DC cut capacitor of VOL1 (CAPL, CAPR) and Tone Bass (DCCL, DCCR) for reducing pop-noise
when “VOL1” or “Tone Bass” are immediately controlled after powered.
This device should be provided the Pre Charge time of at least 2 sec for reducing pop-noise under application
circuit condition.
