FN7438.0
Programmable VCOM
Features
The EL9200, EL9201, and EL9202 represent programmable
• 128 step adjustable sink current
VCOM amplifiers for use in TFT-LCD displays. Featuring 1,
2, and 4 channels of VCOM amplification, respectively, each
device features just a single programmable current source
• EEPROM memory
• 2-pin adjustment and disable
for adding offset to one VCOM output. This current source is
• Single, dual or quad amplifiers
programmable using a single wire interface to one of 128
- 44MHz bandwidth
levels. The value is stored on an internal EEPROM memory.
The EL9200 is available in the 12-pin DFN package and the
EL9201 and EL9202 are available in 24-pin QFN packages.
mAll are specified for operation over the -40°C to +85°C
otemperature range.

CIRCUIT 1
Reference Circuit 1

No connect; not internally connected
Ground connection
Adjustable sink current output pin; the current sinks into the
OUT pin is equal to the DAC setting times the maximum
adjustable sink current divided by 128; see SET pin function
description for the maxim adjustable sink current setting
Maximum sink current adjustment point; connect a resistor
from SET to GND to set the maximum adjustable sink
current of the OUT pin; the maximum adjustable sink
current is equal to (AVDD/20) divided by RSET
Counter enable pin; connect CE to VDD to enable counting
of the internal counter; connect CE to GND to inhibit
counting
Internal counter up/down control and internal EEPROM
programming control input; if CE is high, a mid-to-low
transition increments the 7-bit counter, raising the DAC
setting, increasing the OUT sink current, and lowering the
divider voltage at OUT; a mid-to-high transition decrements
the 7-bit counter, lowering the DAC setting, decreasing the
OUT sink current, and increasing the divider voltage at
OUT; applying 4.9V and above with appropriately arranged
timing will overwrite EEPROM with the contents in the 7-bit
counter; see EEPROM Programming section for details
