Programmable amplifiers and attenuators Digitally controlled filters GENERAL DESCRIPTION The DAC8043 is a high accuracy 12-bit CMOS multiplying Data in the DAC register is converted to an output current by DAC in a space-saving 8-lead PDIP package. Featuring serial the digital-to-analog converter (DAC). data input, double buffering, and excellent analog performance, The fast interface timing of the DAC8043 may reduce timing the DAC8043 is ideal for applications where PC board space is design considerations while minimizing microprocessor wait at a premium. In addition, improved linearity and gain error states. For applications requiring an asynchronous clear function performance permit reduced parts count through the elimination or more versatile microprocessor interface logic, refer to the of trimming components. Separate input clock and load DAC AD5443. control lines allow full user control of data loading and analog Operating from a single 5 V power supply, the DAC8043 is the output. ideal low power, small size, high performance solution to many The circuit consists of a 12-bit serial-in, parallel-out shift register, application problems. It is available in a PDIP package that is a 12-bit DAC register, a 12-bit CMOS DAC, and control logic. compatible with auto-insertion equipment. There is also a Serial data is clocked into the input register on the rising edge 16-lead SOIC package available. of the CLK pulse. When the new data word has been clocked in, it is loaded into the DAC register with the LD input pin. Rev. E Information furnished by Analog Devices is believed to be accurate and reliable.
