GENERAL DESCRIPTION
The
is a high speed, DAC on a single monolithic
chip. It consists of a 10-bit, video DAC with an on-board voltage
reference, complementary outputs, a standard TTL input
interface, and high impedance analog output current sources.
The
has a 10-bit wide input port. A single 5 V or
3.3 V power supply and clock are all that are required to make
the device functional.
The
is fabricated in a complementary metal-oxide
semiconductor (CMOS) process. Its monolithic CMOS
construction ensures greater functionality with low power
dissipation. The
is available in a 24-lead TSSOP
package which includes a power-down mode and an on-board
voltage reference circuit.
