Temperature range is −40°C to +105°C.

The AD5316R and the AD5316 are not pin-to-pin or software compatible.

DC specifications are tested with the outputs unloaded, unless otherwise noted. Upper dead band (10 mV) 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 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.

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 junction temperature may 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 25).

Initial accuracy presolder reflow is ±750 µV; output voltage includes the effects of preconditioning drift. See the Solder Heat Reflow 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 inactive. All DACs active. DAC outputs unloaded.

All DACs powered down.
