TI I G CHARACTERISTICS The q denotes specifications which apply over the full operating temperature

range, otherwise specifications are at TA = 25°C. (See Figure 1) (Note 6)

Note 1: Absolute maximum ratings are those values beyond which the life

of a device may be impaired.

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.

Note 4: DC crosstalk is measured with VCC = 5V and VREF = 4.096V, with

the measured DAC at midscale, unless otherwise noted.

Note 5: RL = 2kΩ to GND or VCC.

Note 6: Guaranteed by design and not production tested.

Note 7: Inferred from measurement at code 256 (LTC2600), code 64

(LTC2610) or code 16 (LTC2620), and at fullscale.

Note 8: 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 9: 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.

HARA TERISTICS The q denotes specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. VCC = 2.5V to 5.5V, VREF ≤ VCC, VOUT unloaded, unless otherwise noted.
