Featuring serial input, double buffering and excellent analog performance, the DAC8043A is ideal for applications where PC board space is at a premium. Improved linearity and gain error performance permit reduced parts count through the elimina- tion 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. Consuming only 10 µA 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 (–40 °C to +85°C) temperature range. DAC8043A is available in a PDIP package, and the low profile 1.75 mm height SOIC-8 surface mount packages. The DAC8043AFRU is available for ultra-compact applications in a thin 1.1 mm TSSOP-8 package.
