1

gain = 2. Linearity calculated using a reduced code range of 4 to 1020.

2

Guaranteed by design and characterization; not production tested.

3

Channel A can have an output current of up to 30 mA. Similarly, Channel B can have an output current of up to 30 mA up to a junction temperature of 100°C.

4

current limit. Operation above the specified maximum operation junction temperature may impair device reliability.

5

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 device.

For example, when sinking 1 mA, the minimum output voltage = 25 Ω × 1 mA = 25 mV (see Figure 26).

6

Initial accuracy presolder reflow is ±750 µV; output voltage includes the effects of preconditioning drift. See the Internal Reference Setup section.

7

Reference is trimmed and tested at two temperatures and is characterized from −40°C to +105°C.

8

Reference temperature coefficient is calculated as per the box method. See the Terminology section for further information.

9

Interface inactive. Both DACs active. DAC outputs unloaded.

10

Both DACs powered down.
