EL5325/EL5325A pdf datasheet (

The EL5325A with external shutdown 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 EL5325A 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 EL5325A has 12 outputs and is available in a 28 Ld
TSSOP package. They are specified for operation over the
full -40°C to +85°C temperature range.
