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 se-
rial interface saves additional circuit board space which
results in low power dissipation. When used with micro-
processors 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 inter-
facing 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.
