ELECTRICAL 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: All voltages are with respect to GND.

Note 3: Linearity and monotonicity are defined from code kL to code 2N–1,

where N is the resolution and kL is the lower end code for which no output

limiting occurs. For VREF = 2.5V and N = 16, kL = 128 and linearity is

defined from code 128 to code 65535. For VREF = 2.5V and N = 12, kL =8

and linearity is defined from code 8 to code 4095.

Note 4: Inferred from measurement at code 128 (LTC2655-16), or code 8

(LTC2655-12).

Note 5: DC Crosstalk is measured with VCC = 5V and using internal

reference, with the measured DAC at mid-scale.

Note 6: This IC includes current limiting that is intended to protect the

device during momentary overload conditions. Junction temperature can

exceed the rated maximum during current limiting. Continuous operation

above the specified maximum operating junction temperature may impair

device reliability.

Note 7: Temperature coefficient is calculated by dividing the maximum

change in output voltage by the specified temperature range. Maximum

temperature coefficient is guaranteed for C-grade only.

Note 8: Digital inputs at 0V or VCC.

Note 9: Guaranteed by design and not production tested.

Note 10: Internal Reference mode. DAC is stepped 1/4 scale to 3/4 scale

and 3/4 scale to 1/4 scale. Load is 2kΩ in parallel with 200pF to GND.

Note 11: VCC = 5V (-H Options) or VCC = 3V (-L Options), internal

reference mode. DAC is stepped ±1 LSB between half-scale and

half-scale – 1. Load is 2kΩ n parallel with 200pF to GND.

Note 12: DAC to DAC Crosstalk is the glitch that appears at the output

of one DAC due to a full scale change at the output of another DAC. It is

measured with VCC = 5V and using internal reference, with the measured

DAC at mid-scale.

Note 13: CB = Capacitance of one bus line in pF.

Note 14: Gain error specification may be degraded for reference input

voltages less than 1V. See Gain Error vs Reference Input Curve in the

Typical Performance Characteristics section.
