Note 2:
The DNL and INL are measured with the potentiometer configured as a variable resistor. For the 3-terminal potentiometers
(MAX5432/MAX5433), H is unconnected and L = GND. At V
DD
= 5V, W is driven with a source current of 80μA for the 50k
configuration, and 40μA for the 100k
configuration. At V
DD
= 3V, W is driven with a source current of 40μA for the 50k
configuration, and 20μA for the 100k
configuration.
Note 3:
The DNL and INL are measured with the potentiometer configured as a voltage-divider with H = V
DD
and L = GND
(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
(V
DD
- 0.5V) and (GND + 0.5V). See the Supply Current vs. Digital Input Voltage graph in the
Typical Operating Characteristics
.
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.
