POWER SUPPLY
Supply Voltage VDD 2.7 5.5 V Static Supply Current IDD CS = U/D = GND or VDD 1.5 µA TA < +50°C 10.45 11.55 Programming Voltage PV V TA ≥ +50°C 11.00 11.55 Programming Current IPV VPV = 11V 4 5 mA
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 20µA for the MAX5527, 40µA for the MAX5528, and 200µA 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.
