AD5439Dual 10-Bit, High Bandwidth, Multiplying DAC with Serial Interface | Integrated Circuits (ICs) | 3 | Active | TheAD5429/ AD5439 /AD5449are CMOS, 8-, 10-, and 12-bit, dual-channel, current output digital-to-analog converters (DAC), respectively. These devices operate from a 2.5 V to 5.5 V power supply, making them suited to battery-powered and other applications.As a result of being manufactured on a CMOS submicron process, these parts offer excellent 4-quadrant multiplication characteristics, with large signal multiplying bandwidths of 10 MHz.The applied external reference input voltage (VREF) determines the full-scale output current. An integrated feedback resistor (RFB) provides temperature tracking and full-scale voltage output when combined with an external current-to-voltage precision amplifier.These DACs use a double-buffered, 3-wire serial interface that is compatible with SPI, QSPI™, MICROWIRE™, and most DSP interface standards. In addition, a serial data out (SDO) pin allows daisy-chaining when multiple packages are used. Data readback allows the user to read the contents of the DAC register via the SDO pin. On power-up, the internal shift register and latches are filled with 0s, and the DAC outputs are at zero scale.The AD5429 / AD5439 / AD5449 DACs are available in 16-lead TSSOP packages. The EV-AD5415 / 49SDZ evaluation board is available for evaluating DAC performance.

AD544112-Bit Serial Input Multiplying DAC | Data Acquisition | 2 | Active | The AD5441 is an improved high accuracy 12-bit multiplying digital-to-analog converter (DAC) in space-saving 8-lead packages. Featuring serial input, double buffering, and excellent analog performance, the AD5441 is ideal for applications where PC board space is at a premium. Improved linearity and gain error performance permit reduced part counts 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 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 is 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 DAC.Consuming only 1 μA from a single 5 V power supply, the AD5441 is the ideal low power, small size, high performance solution to many application problems.The AD5441 is specified over the extended industrial (−40°C to +125°C) temperature range. It is available in an 8-lead LFCSP and an 8-lead MSOP.ApplicationsIdeal for PLC applications in industrial controlProgrammable amplifiers and attenuatorsDigitally controlled calibration and filtersMotion control systems |
