... AD5316/AD5326 DACs. This interface is SMBus-compatible at V < 3 The AD5306/AD5316/AD5326 has a 7-bit slave address. The five MSBs are 00011, and the two LSBs are determined by the state of the A0 and A1 pins. The facility to make hardwired changes to A0 and A1 allows the user to have up to four of these devices on one bus ...

... AD5306/AD5316/AD5326 WRITE OPERATION When writing to the AD5306/AD5316/AD5326 DACs, the user must begin with an address byte ( 0), after which the DAC acknowledges that it is prepared to receive data by pulling SDA low. This address byte is followed by the pointer byte, which is also acknowledged by the DAC. Two bytes of data are then written to the DAC, as shown in Figure 33 ...

... LDAC was low. Normally, when LDAC is low, the DAC registers are filled with the contents of the input registers. In the AD5306/AD5316/AD5326, the part updates the DAC register only if the input register has been changed since the last time the DAC register was updated, thereby removing unnecessary digital crosstalk ...

... AD5306/AD5316/AD5326 APPLICATIONS TYPICAL APPLICATION CIRCUIT The AD5306/AD5316/AD5326 can be used with a wide range of reference voltages where the devices offer full one-quadrant multiplying capability over a reference range More typically, these devices are used with a fixed precision- reference voltage. Suitable references for 5 V operation are the AD780 and REF192 (2 ...

... ADDITIONAL PINS OMITTED FOR CLARITY Figure 39. Window Detection COARSE AND FINE ADJUSTMENT USING THE AD5306/AD5316/AD5326 Two of the DACs in the AD5306/AD5316/AD5326 can be paired together to form a coarse and fine adjustment function, as shown in Figure 40. DAC A is used to provide the coarse adjustment while DAC B provides the fine adjustment. Varying the ratio of R1 and R2 changes the relative effect of the coarse and fine adjustments ...

... The star ground point should be established as close as possible to the device. The AD5306/ AD5316/AD5326 should have ample supply bypassing of 10 μF in parallel with 0.1 μF on the supply located as close to the package as possible, ideally right up against the device. The 10 μF capacitors are the tantalum bead type. The 0.1 μ ...
