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

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).

Interface inactive. All DACs active. DAC outputs unloaded.
