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 110°C.

4

current limit, but operation above the specified maximum operation junction temperature can 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

devices. For example, when sinking 1 mA, the minimum output voltage = 25 Ω × 1 mA = 25 mV (see Figure 23).

6

Initial accuracy presolder reflow is ±750 µV; output voltage includes the effects of preconditioning drift.

7

Interface inactive. Both DACs active. DAC outputs unloaded.

8

Both DACs powered down.

AC CHARACTERISTICS

noted. Temperature range = −40°C to +105°C, typical at 25°C. Guaranteed by design and characterization, not production tested.
