EL5225 pdf datasheet (10-Chann

The EL5225 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 3-wire, SPI compatible interface.
A number of the EL5225 can be stacked for applications
requiring more than 10 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 EL5225 has 10 outputs, and is available in the 24-pin
TSSOP package. They are specified for operation over the
full -40°C to +85°C temperature range.
