FEATURES Compact SO-8 and TSSOP Packages True 12-Bit Accuracy 5 V Operation <10 A Fast 3-Wire Serial Input Fast 1 s Settling Time 2.4 MHz 4-Quadrant Multiply BW Pin-for-Pin Upgrade for DAC8043 Standard and Rotated Pinout APPLICATIONS Ideal for PLC Applications in Industrial Control Programmable Amplifiers and Attenuators Digitally Controlled Calibration and Filters Motion Control Systems
The is an improved high accuracy 12-bit multiplying digital-to-analog converter in space-saving 8-lead packages. Featuring serial input, double buffering and excellent analog performance, the DAC8043A is ideal for applications where PC board space at a premium. 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 a 12-bit serial-in/parallel-out shift register, 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. Consuming only 10 �A from a single 5 V power supply, the DAC8043A is the ideal low power, small size, high performance solution to many application problems. The DAC8043A is specified over the extended industrial to +85�C) temperature range. DAC8043A is available in plastic DIP, and the low profile 1.75 mm height SO-8 surface mount packages. The DAC8043AFRU is available for ultracompact applications in a thin mm TSSOP-8 package.

CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the DAC8043A features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
