TIMING CHARACTERISTICS The l denotes the speciﬁcations which apply over the full operating temperature

range, otherwise speciﬁcations are at TA = 25°C. VCC = 4.5V to 5.5V, VOUT unloaded unless otherwise speciﬁed.

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: High temperatures degrade operating lifetimes. Operating lifetime

is derated at temperatures greater than 105°C.

Note 4: 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/ VFS), rounded

to the nearest whole code. For VFS = 2.5V and N = 12, kL = 26 and linearity

is deﬁned from code 26 to code 4,095. For VFS = 4.096V and N = 12, kL =

16 and linearity is deﬁned from code 16 to code 4,095.

Note 5: Inferred from measurement at code 16 (LTC2636-12), code 4

(LTC2636-10) or code 1 (LTC2636-8), and at full-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: Digital inputs at 0V or VCC.

Note 8: Guaranteed by design and not production tested.

Note 9: 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 100pF to GND.

Note 10: Temperature coefﬁcient is calculated by dividing the maximum

change in output voltage by the speciﬁed temperature range.

Note 11: Thermal resistance of MSOP package limits IOUT to

–5mA ≤ IOUT ≤ 5mA for H-grade MSOP parts and VCC = 5V ±10%.
