DESCRIPTION

The DAC8043 is a 12-bit current output multiplying

digital-to-analog converter (DAC) that is packaged in a

space-saving, surface-mount 8-pin SOIC. Its 3-wire serial

interface saves additional circuit board space which

results in low power dissipation. When used with microprocessors

having a serial port, the DAC8043 minimizes

the digital noise feedthrough from its input to output.

The serial port can be used as a dedicated analog bus and

kept inactive while the DAC8043 is in use. Serial interfacing

reduces the complexity of opto or transformer

isolation applications.

The DAC8043 contains a 12-bit serial-in, parallel-out

shift register, a 12-bit DAC register, a 12-bit CMOS

DAC, and control logic. Serial input (SRI) data is clocked

into the input register on the rising edge of the clock

(CLK) pulse. When the new data word had been clocked

in, it is loaded into the DAC register by taking the LD

input low. Data in the DAC register is converted to an

output current by the D/A converter.

The DAC8043 operates from a single +5V power supply

which makes the DAC8043 an ideal low power, small

size, high performance solution for several applications.
