Data Sheet
8-Channel TFT-LCD Reference Voltage
Generator
The EL5126 is designed to produce
the reference voltages required in
TFT-LCD applications. Each output is
programmed to the required voltage with 10 bits of
resolution. Reference pins determine the high and low
voltages of the output range, which are capable of swinging
to either supply rail. Programming of each output is
performed using the serial interface.
A number of the EL5126 can be stacked for applications
requiring more than 8 outputs. The reference inputs can be
tied to the rails, enabling each part to output the full voltage
range, or alternatively, they can be connected to external
resistors to split the output range and enable finer
resolutions of the outputs.
The EL5126 has 8 outputs and is available in a 32-pin LPP
package. It is specified for operation over the full -40°C to
+85°C temperature range.
