1 Static Performance tested with the outputs unloaded, unless otherwise noted. Linearity calculated using a reduced code range of 256 to 65279.

2 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.

3 Voltage reference temperature coefficient is calculated as per the box method. See the Terminology section for further information.

4 The peak voltage glitch seen on the VOUTn channels when a different channel is monitored through MUX_OUT_SELECT_0(SEL).

5 Interface inactive. All channels in operating mode 0 with outputs unloaded.

6 Interface inactive. All channels in either operating mode 1, 2 or 3.

AC SPECIFICATIONS

VDD = 2.7V to 5.5V, 1.08V ≤ IOVDD ≤ 1.98V, VREF = 2.5V (external), RL = 2kΩ to GND, CL = 200pF, and all specifications are TJ = −40°C to

+125°C, typical at TA = 25°C, unless otherwise noted.
