FUNCTION
INN
DVR_OUT
1 Negative (inverting) input of the VCOM buffer op
amp. This pin is used to provide feedback from
the end point of the VCOM trace.
2 Adjustable Sink Current Output Pin. The current
sunk into the DVR_OUT pin is equal to the DAC
setting times the maximum adjustable sink
current divided by 256. See the “SET” pin
function description below (pin 9) for the
maximum adjustable sink current setting. Also
tied to the non-inverting input of buffer amp.
AVDD
3 Analog Power Supply Input. Bypass to GND
with 0.1µF capacitor.
WP 4 EEPROM Write Protect. Active Low.
0 = Programming disabled; 1 = Programming
allowed.
GND 5 Ground connection.
VDD 6 Digital power supply input. Bypass to GND with
0.1µF capacitor.
SDA 7 I2C Serial Data Input
SCL 8 I2C Clock Input
SET
VCOM_OUT
9 Maximum Sink Current Adjustment Point.
Connect a resistor from SET to GND to set the
maximum adjustable sink current of the
DVR_OUT pin. The maximum adjustable sink
current is equal to (AVDD/20) divided by RSET.
10 Output of the buffer amplifier
PAD - Thermal pad should be connected to system
ground plane to optimize thermal performance.
