How accurate can the chip be calibrated to?
As for the accuracy of calibration, zeroing out the offset at the calibration points is achievable but it is always a more proper approach to look at the overall…
If “Enable Always on Ext Range” is used, how much power consumption is increased?
For AVDD and AVSS, the power consumption for both supplies is increased depending on the load. For example, at 2mA…
How to reduce the transient response when switching between external and internal current range?
When switching between the internal and external current ranges, one must bear in mind that force amplifiers…
Can the current drive of AD5522 be extended without the use of ganging?
Implementing gang mode to increase the current drive of AD5522 can be a bit tricky due to some factors including the Rsense and…
When is SW1 connected to the Hi-Z (MEASVH) position which register and bit controls it?
SW1 goes to MEASVH when the force amplifier is set to high-Z. It is controlled by the same bit that enables the…
Can AD5522 be used in voltmeter mode and how is it done?
Yes, it can be used in voltmeter mode. Set FORCE1 bit to 1 to put the force amp in High-Z mode.
The Force function for Channel 3 should…
When does the loading of the data to the X2 DAC occurs?
There are two scenarios that helps explain this which is present in the Timing Diagram of the AD5522 Datasheet Rev. F page 13.
For scenario…
