Note 1: All devices are production tested at TA = +25°C, and are guaranteed by design for TA = -40°C to +105°C.
Note 2: The wiper resistance is measured by driving the wiper terminal with a source of 20A for the MAX5527, 40A for the
MAX5528, and 200A for the MAX5529.
Note 3: Wiper at midscale with a 10pF load.
Note 4: Digital timing is guaranteed by design, not production tested.
Note 5: Wiper setting time is measured for a single step from U/D transition until wiper voltage reaches 90% of final value.
Note 6: Power-up time is the period of time from when the power supply is applied, until the serial interface is ready for writing.
