3 / 8 page +2.7V to +5.5V, Low-Power, Quad, Parallel 8-Bit DAC with Rail-to-Rail Voltage Outputs _______________________________________________________________________________________ 3 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) / VREF]. 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., VREF · 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. Note 8: If LDAC is activated prior to WR’s rising edge, it must stay low for tLD (or longer) after WR goes high. ELECTRICAL CHARACTERISTICS (continued) (VDD = VREF = +2.7V to +5.5V, RL = 10k Ω, CL = 100pF, TA = TMIN to TMAX, unless otherwise noted. Typical values are at VDD = VREF = +3V and TA = +25°C.)
