+2.7V to +5.5V, Low-Power, Triple, Parallel
8-Bit DAC with Rail-to-Rail Voltage Outputs
ELECTRICAL CHARACTERISTICS (continued)
(VDD = +2.7V to +5.5V, RL = 10kΩ, CL = 100pF, TA = TMIN to TMAX, unless otherwise noted. Typical values are at VDD = +3V and
TA = +25°C.)

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 (VF0,meas - ZCE - VF0,ideal) / VDD]. Where VF0,meas is the DAC output voltage with input code F0 hex, and
VF0,ideal is the ideal DAC output voltage with input code F0 hex (i.e., VDD · 240 / 256).
Note 3: Output settling time is measured from the 50% point of the falling edge of WR to ±1/2LSB of VOUT’s final value.
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.
Note 5: Digital Feedthrough is defined as the glitch energy at any DAC output in response to a full-scale step change on all eight
data inputs with WR at VDD.
Note 6: RL = ∞ , digital inputs at GND or VDD.
Note 7: Timing measurement reference level is (VIH + VIL) / 2.
