TIMING CHARACTERISTICS
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Linearity and monotonicity are defined from code KL to code
2N – 1, where N is the resolution and KL is given by KL = 0.016(2N/VREF),
rounded to the nearest whole code. For VREF = 4.096V and N = 16, KL =
256 and linearity is defined from code 256 to code 65,535.
Note 3: Digital inputs at 0V or VCC.
LTC2601/LTC2611/LTC2621
Note 4: Guaranteed by design and not production tested.
Note 5: Inferred from measurement at code KL = 0.016(2N/VREF) and at
full scale.
Note 6: VCC = 5V, VREF = 4.096V. DAC is stepped 1/4 scale to 3/4 scale and
3/4 scale to 1/4 scale. Load is 2k in parallel with 200pF to GND.
Note 7: VCC = 5V, VREF = 4.096V. DAC is stepped ±1LSB between half scale
and half scale – 1. Load is 2k in parallel with 200pF to GND.
Note 8: These specifications apply to LTC2601/LTC2601-1,
LTC2611/LTC2611-1, LTC2621/LTC2621-1
