Note 1: Reduced digital code range (code 00 hex to code F0 hex) due to swing limitations when the output amplifier is loaded.
Note 2: Gain error is: [100 (V

Note 4: Channel-to-Channel Isolation is defined as the glitch energy at a DAC output in response to a full-scale step change on any

other DAC output. The measured channel has a fixed code of 80 hex.
