LM8207
TFT 18 Gamma Buffer + V
COM
Driver + Voltage Reference
General Description
The LM8207 is a combination of 18-channel gamma buffers,
a V
driver and a temperature compensated internal volt-
age reference. It is designed for buffering voltage levels and
driving high capacitive loads in large TFT panels. The
gamma buffers are individually optimized to the input/output
requirements of their respective gamma position to cover the
whole voltage range from rail to rail. Any desired gamma
correction curve can be obtained by combining the gamma
buffers with external resistors. The V
COM
driver has a high
output current capability and is stable with large capacitive
loads, typical for large panel sizes. This will result in a fast
recovery time for large voltage variations at the output. The
internal band gap reference can be used to form a highly
stable voltage to generate the gamma correction voltages. In
combination with the internal amplifier, the reference voltage
can be programmed to voltages up to the positive rail. The
LM8207 is offered in a 48-pin TSSOP package.
