• Manufacturer Part Number: max5774
• Description: 32-channel, 14-bit, Voltage-output Dacs With Serial Interface
• Manufacturer: Maxim Integrated Products, Inc.

32-Channel, 14-Bit, Voltage-Output
DACs with Serial Interface
Figure 6. Example 1 of a Daisy-Chain Data Sequence
W/WD0 = 32-bit word with a write command; WD0 writes data for device 0. The 0 refers to the position in the daisy chain (0 is closest
to the bus master). Devices 1 and 2 are devices further down the chain.
RDn/X = 32-bit word with a 14-bit read output from from device “n” followed by don’t-care bits.
X = Don’t care (for X in the data or command position).
Figure 7. Example 2 of a Daisy-Chain Data Sequence
W/WD0 = 32-bit word with a write command; WD0 writes data for device 0. The 0 refers to the position in the daisy chain (0 is closest
to the bus master). Devices 1 and 2 are devices further down the chain.
RDn/X = 32-bit word with a 14-bit read output from from device “n” followed by don’t-care bits.
X = Don’t care (for X in the data or command position).
