The EL5226 and EL5326 are 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 I2C serial interface.
A number of the EL5226 and EL5326 can be stacked for
applications requiring more than 12 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 EL5226 has 10 outputs and the EL5326 has 12 outputs
and both are available in a 28-pin TSSOP package. They
are specified for operation over the full -40°C to +85°C
temperature range.
