The AD5330/AD5331/AD5340/AD5341 have a parallel interface. CS selects the device and data is loaded into the input registers on the rising edge of WR.
The GAIN pin allows the output range to be set at 0 V to VREF or 0 V to 2 × VREF.
Input data to the DACs is double-buffered, allowing simultaneous update of multiple DACs in a system using the LDAC pin.
An asynchronous CLR input is also provided, which resets the contents of the input register and the DAC register to all zeros. These devices also incorporate a power-on reset circuit that ensures that the DAC output powers on to 0 V and remains there until valid data is written to the device.
The AD5330/AD5331/AD5340/AD5341 are available in thin shrink small outline packages (TSSOP).

Data Sheet, Rev. A, 2/08
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
The EVAL-AD5341DBZ evaluation board helps users quickly prototype new AD5341 circuits and reduce design times. The AD5341 operates from a single 2.5 V to 5.5 V supply.
For full data, see the AD5341 data sheet, which must be used in conjunction with user guide UG-982 when using the evaluation board. The EVAL-AD5341DBZ interfaces to the USB port of a PC via the SDP-B controller board. Software is available that allows users to program the AD5341.
The EVAL-AD5341DBZ evaluation board requires the EVAL-SDP-CB1Z board (SDP-B controller board).
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
