Reading Multiple Bytes from a Slave: The read oper-
ation can be used to read multiple bytes with a single
transfer. When reading bytes from the slave, the master
simply ACKs the data byte if it desires to read another
byte before terminating the transaction. After the mas-
ter reads the last byte it must NACK to indicate the end
of the transfer and generates a stop condition.
Application Information
Power Supply Decoupling
To achieve best results, it is highly recommended that a
decoupling capacitor is used on the I.C. power supply
pins. Typical values of decoupling capacitors are 0.01F
and 0.1F. Use a high-quality, ceramic, surface-mount
capacitor, and mount it as close as possible to the VCC
and GND pins of the I.C. to minimize lead inductance.
High Resistor Terminal Voltage
It is permissible to have a voltage on the resistor-high
terminals that is higher than the voltage connected to
VCC. For instance, connecting VCC to 3.0V while one or
more of the resistor high terminals are connected to
5.0V allows a 3V system to control a 5V system. The
5.5V maximum still applies to the limit on the resistor
high terminals regardless of the voltage present on VCC.

DESIGN NOTES:
1. IN THIS APPLICATION A NUMBER OF LED DRIVERS ARE SET USING THE DS3906'S VARIABLE RESISTORS.
2. THE PARALLEL COMBINATION OF THE DS3906 VARIABLE RESISTOR R0 AND 105
(REXT0) IS EQUIVALENT TO A VARIABLE
RESISTOR WITH LINEAR STEP INCREMENTS OF 0.6
RANGING FROM 66 TO 101. THE SAME APPLIES FOR RESISTOR 1 (R1).
THE PARALLEL COMBINATION OF R2 AND 310
(REXT2) IS EQUIVALENT TO A VARIABLE RESISTOR WITH LINEAR STEP INCREMENTS OF
1
RANGING FROM 187 TO 255.
3. VALUES LARGER THAN THE SHOWN EXTERNAL RESISTORS (REXT0, REXT1, AND REXT2) RESULT IN LARGER STEP INCREMENTS AND
RESISTOR VALUES LOWER THAN THE SHOWN VALUES RESULT IN SMALLER STEP INCREMENTS. REFER TO THE RESISTOR TABLES AND
COMPUTE EQUIVALENT RESISTANCE TO FIND OUT THE RANGES.
