with gain = 2. Linearity calculated using a reduced code range of 256 to 65,280 (AD5686) or 12 to 4080 (AD5684).
3
Guaranteed by design and characterization; not production tested.
4
Channel A and Channel B can have a combined output current of up to 30 mA. Similarly, Channel C and Channel D can have a combined output current of up to
30 mA up to a junction temperature of 110°C.
5
V
DD
= 5 V. The device includes current limiting that is intended to protect the device during temporary overload conditions. Junction temperature can be exceeded
during current limit. Operation above the specified maximum operation junction temperature may impair device reliability.
6
When drawing a load current at either rail, the output voltage headroom with respect to that rail is limited by the 25 Ω typical channel resistance of the output
devices. For example, when sinking 1 mA, the minimum output voltage = 25 Ω × 1 mA = 25 mV (see Figure 23).
7
Interface inactive. All DACs active. DAC outputs unloaded.
8
All DACs powered down.
