ELECTRICAL CHARACTERISTICS (continued)
(VDD = +5V ±5%, VREF = +2.5V, AGND = DGND = 0, TA MIN to TMAX, unless otherwise noted.)
TIMING CHARACTERISTICS
(VDD = +5V ±5%, VREF = +2.5V, AGND = DGND = 0, CMOS inputs, TA = TMIN to TMAX, unless otherwise noted.)
Note 1: Gain Error tested at VREF = 2.0V, 2.5V, and 3.0V.
Note 2: ROUT tolerance is typically ±20%.
Note 3: Min/max range guaranteed by gain-error test. Operation outside min/max limits will result in degraded performance.
Note 4: Reference input resistance is code dependent, minimum at 8555 hex.
Note 5: Slew-rate value is measured from 0% to 63%.
Note 6: Guaranteed by design. Not production tested.
Code = 0000 hex; CS = VDD; LDAC = 0;
SCLK, DIN = 0 to VDD levels
Major-carry transition
VIN = 0
Code = 0000 hex, VREF = 1Vp-p at 100kHz
Code = 0000 hex
