... The LSB size is V /65,536. REF SERIAL INTERFACE The AD5541A is controlled by a versatile 3- or 4-wire serial interface that operates at clock rates MHz and is compatible with SPI, QSPI, MICROWIRE, and DSP interface standards. The timing diagram is shown in Figure 3. The AD5541A has a separate serial input register from the 16-bit ...

... UNIPOLAR OUTPUT OPERATION This DAC is capable of driving unbuffered loads of 60 kΩ. Unbuffered operation results in low supply current, typically 300 μA, and a low offset error. The AD5541A provides a unipolar output swing ranging from Figure 31 shows a typical unipolar output voltage circuit. The code table for this mode of operation is shown in Table 8 ...

... POWER-ON RESET The AD5541A has a power-on reset function to ensure that the output known state on power-up. On power-up, the DAC register contains all 0s until the data is loaded from the serial register. However, the serial register is not cleared on power-up ...

... AD5541A is mounted so that the analog and digital sections are separated and confined to certain areas of the board. If the AD5541A system where multiple devices require an analog ground-to-digital ground connection, make the connection at one point only. Establish the star ground point as close as possible to the device. The AD5541A should have ample supply bypassing of 10 μ ...

... AD5541A DECODING MULTIPLE DACS The CS pin of the AD5541A can be used to select one of a number of DACs. All devices receive the same serial clock and serial data, but only one device receives the CS signal at any one time. The DAC addressed is determined by the decoder. There is some digital feedthrough from the digital input lines ...
