ORDERING INFORMATION

The MC144112 contains four independent DACs which are controlled

through a common serial data port. When all DACs are utilized, there are 24 bits

in the serial data stream. However, if not all DACs are utilized, the bit stream

length may be reduced by up to six bits per unused DAC.

For new designs, the MC144112 is preferred over the MC144110 and

MC144111. The newer MC144112 offers a wider operating temperature range,

lower operating supply voltage, and lower supply current.
