NOTES: (1) For channels 2-5, fed into MUX directly. (2) LSB means Least Significant Bit. (3) DACs are tested without output load. (4) Measured from code 010
to FFF. (5) Internal reference voltage has been optimized for lowest drift from 0°C to +85°C. (6) Applies to all amplifiers; see Figure 2. (7) Offset current will double
for each 10°C of temperature increase. See Operational Amplifier section. (8) Ensured by design.
