DC specifications tested with the outputs unloaded, unless otherwise noted. Upper dead band = 10 mV; it exists only when VREF = VDD with gain = 1 or when VREF/2 =

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

Guaranteed by design and characterization; not production tested.

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.

VDD = 5 V. The device includes current limiting that is intended to protect the device during temporary overload conditions. Junction temperature may be exceeded

during current limit, but operation above the specified maximum operation junction temperature can impair device reliability.

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 28).

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

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

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

Interface is inactive, both DACs are active, and DAC outputs are unloaded.

Both DACs are powered down.

AC CHARACTERISTICS

VDD = 2.7 V to 5.5 V; RL = 2 kΩ to GND; CL = 200 pF to GND; 1.62 V ≤ VLOGIC ≤ 5.5 V; all specifications TMIN to TMAX, unless otherwise noted.

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