The paddle should be connected to GND. This will also apply to the AD5624R/AD5644R/AD5664R
nanoDACs are a portfolio of products which combine small package, low power and low cost digital to analog conversion.
nanoDACs are monotonic DACs which can be powered off a single 3V or 5V supply and are available in the industries smallest packages…
The AD5664R has two on-chip reference options available, 1.25V and 2.5V. What is the recommended supply voltage in each case?
It must be stressed that depending on the application performance requirements, all nanoDACs can be used in both open and closed loop systems.
In an open loop application the DAC drives the load (a valve or an actuator, for example) directly while in…
