Description

The TPC219 is faimily of high accuracy DACs with 16, 14

and 12bit resolution which are all pin-compatible.

The device includes a 2.5V internal reference, which can

be used to reduce system complexity

Several gain options could be selected to provide different

full scale output voltages, 1.25V, 2.5V and 5V.

The device operates under a single analog supply, and

has seperate VIO supply for digital communication. The

communication is performed through a serial interface, and

can operate under wide range VIO supply voltage.

A power on reset circuit is intergraged to maintain the DAC

output at zero scale or midscale.

The device is characterized for temeprature range of -40℃

to 125 ℃. And is available in small package of QFN and

WLCSP.
