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.

CAUTION: 1. Do not apply voltages higher than V
potential on any terminal except V
control inputs are ESD protected: however, permanent damage may occur on
unprotected units from high-energy electrostatic fields. Keep units in conduc­tive foam at all times until ready to use. 3. Use proper anti-static handling
procedures. 4. Absolute Maximum Ratings apply to both packaged devices.
Stresses above those listed under Absolute Maximum Ratings may cause

PACKAGE

(1)

Any integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.

ESD damage can range from subtle performance degrada­tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet
published specifications.

Digital Inputs: All digital inputs of the DAC8043 incorpo­rate on-chip ESD protection circuitry. This protection is
designed and has been tested to withstand five 2500V
positive and negative discharges (100pF in series with 1500Ω)
applied to each digital input.

Analog Pins: Each analog pin has been tested to Burr­Brown’s analog ESD test consisting of five 1000V positive
and negative discharges (100pF in series with 1500Ω) ap­plied to each pin. V

and RFB show some sensitivity.
