LTC1695

ELECTRICAL CHARACTERISTICS The q denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. VCC = 5V unless otherwise stated.

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: INL, DNL specs are specified under a 1mA ILOAD condition to keep the

linear regulator from operating in dropout at higher DAC codes. DNL is

measured from code 0 to code 63, taking into account the untrimmed offset

at code 0. Please refer to the Definitions section for more details.
