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: Nonlinearity and monotonicity are defined from code 4 to code

255 for the LTC1665 and from code 20 to code 1023 for the LTC1660.

See Applications Information.

Note 4: Load is 10kΩ in parallel with 100pF.

i.e., codes 26 and 230 for the LTC1665 or codes 102 and 922 for the

LTC1660.

Note 6: Guaranteed by design and not production tested.

Note 7: Measured at code 4 for the LTC1665 and code 20 for the

LTC1660.
