GENERAL DESCRIPTION
8-Pin Epoxy DIP
(P-Suffix)
8-Pin Cerdip
(Z-Suffix)
The DAC8043 is a high accuracy 12-bit CMOS multiplying
DAC in a space-saving 8-pin mini-DIP package. Featuring serial
data input, double buffering, and excellent analog performance,
the DAC8043 is ideal for applications where PC board space is
at a premium. Also, improved linearity and gain error performance
permit reduced parts count through the elimination of trimming
components. Separate input clock and load DAC control lines
allow full user control of data loading and analog output.
The circuit consists of a 12-bit serial-in, parallel-out shift regis-
ter, a 12-bit DAC register, a 12-bit CMOS DAC, and control
logic. Serial data is clocked into the input register on the rising
edge of the CLOCK pulse. When the new data word has been
clocked in, it is loaded into the DAC register with the
LD
input
pin. Data in the DAC register is converted to an output current
by the D/A converter.
The DAC8043鈥檚 fast interface timing may reduce timing design
considerations while minimizing microprocessor wait states. For
applications requiring an asynchronous CLEAR function or more
versatile microprocessor interface logic, refer to the PM-7543.
Operating from a single +5 V power supply, the DAC8043 is
the ideal low power, small size, high performance solution to
many application problems. It is available in plastic and cerdip
packages that are compatible with auto-insertion equipment.
