1 DC specifications tested with the outputs unloaded, unless otherwise noted. Upper dead band = 10 mV and exists only when VREF = VDD with gain = 1 or when VREF/2 =
VDD with gain = 2. Linearity calculated using a reduced code range of 12 to 4080.
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 VDD = 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.
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 25).
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.
