Note 2: The DNL and INL are measured with the potentiometer configured as a variable resistor. For the 3-terminal potentiometers

(MAX5432/MAX5433 only). The wiper terminal is unloaded and measured with an ideal voltmeter.

Note 4: Full-scale error is defined as

Note 5: Zero-scale error is defined as

Note 6: The wiper resistance is the worst value measured by injecting the currents given in Note 2 into W with L = GND.

Note 7: The device draws current in excess of the specified supply current when the digital inputs are driven with voltages between

Note 8: Wiper is at midscale with a 10pF capacitive load. Potentiometer set to midscale, L = GND, an AC source is applied to H,

and the output is measured as 3dB lower than the DC W/H value in dB.

Note 9: This is measured from the STOP pulse to the time it takes the output to reach 50% of the output step size (divider mode). It

is measured with a maximum external capacitive load of 10pF.

Note 10: The programming current exists only during NV writes (12ms typ).

Note 11: Digital timing is guaranteed by design and characterization, and is not production tested.

Note 12: An appropriate bus pullup resistance must be selected depending on board capacitance. Refer to the I

tion document linked to this web address: www.semiconductors.philips.com/acrobat/literature/9398/39340011.pdf

Note 13: The idle time begins from the initiation of the stop pulse.
