MAX5418NETA+T
256-Tap, Nonvolatile, I²C-Interface, Digital Potentiometers
General Description
The MAX5417/MAX5418/MAX5419 nonvolatile, linear-
taper, digital potentiometers perform the function of amechanical potentiometer by replacing the mechanics
with a simple 2-wire digital interface, allowing communi-cation with multiple devices. Each device performs the
same function as a discrete potentiometer or variable
resistor and has 256 tap points.
The devices feature an internal, nonvolatile EEPROMused to store the wiper position for initialization during
power-up. The fast-mode I2C-compatible serial interface
allows communication at data rates up to 400kbps, mini-mizing board space and reducing interconnection com-
plexity in many applications. Each device is available withone of four factory-preset addresses (see the Ordering
Information/Selector Guide) and features an address
input for a total of eight unique address combinations.
The MAX5417/MAX5418/MAX5419 provide three nomi-nal resistance values: 50kΩ(MAX5417), 100kΩ
(MAX5418), or 200kΩ(MAX5419). The nominal resistor
temperature coefficient is 35ppm/°C end-to-end, andonly 5ppm/°C ratiometric. This makes the devices ideal
for applications requiring a low-temperature-coefficientvariable resistor, such as low-drift, programmable gain-
amplifier circuit configurations.
The MAX5417/MAX5418/MAX5419 are available in a
3mm x 3mm 8-pin TDFN package, and are specifiedover the extended -40°C to +85°C temperature range.

Note 1:The DNL and INL are measured with the potentiometer configured as a voltage-divider with H = VDDand L = GND. The
wiper terminal is unloaded and measured with a high-input-impedance voltmeter.
Note 2:The DNL and INL are measured with the potentiometer configured as a variable resistor. H is unconnected and L = GND.
For the 5V condition, the wiper terminal is driven with a source current of 80µA for the 50kΩconfiguration, 40µA for the
100kΩconfiguration, and 20µA for the 200kΩconfiguration. For the 3V condition, the wiper terminal is driven with a source
current of 40µA for the 50kΩconfiguration, 20µA for the 100kΩconfiguration, and 10µA for the 200kΩconfiguration.
Note 3:The wiper resistance is measured using the source currents given in Note 2. For operation to VDD= 2.7V, see Wiper
Resistance vs. Temperature in the Typical Operating Characteristics.
Note 4:The device draws higher supply current when the digital inputs are driven with voltages between (VDD- 0.5V) and (GND +
0.5V). See Supply Current vs. Digital Input Voltage in the Typical Operating Characteristics.
Note 5:Wiper at midscale with a 10pF load (DC measurement). L = GND; an AC source is applied to H; and the W output is mea-
sured. A 3dB bandwidth occurs when the AC W/H value is 3dB lower than the DC W/H value.
Note 6:The programming current operates only during power-up and NV writes.
Note 7:SCL clock period includes rise and fall times tRand tF. All digital input signals are specified with tR= tF= 2ns and timed
from a voltage level of (VIL+ VIH) / 2.
Note 8:Wiper settling time is the worst-case 0% to 50% rise time measured between consecutive wiper positions. H = VDD,
L = GND, and the wiper terminal is unloaded and measured with a 10pF oscilloscope probe (see the Typical Operating
Characteristicsfor the tap-to-tap switching transient).
Note 9:An appropriate bus pullup resistance must be selected depending on board capacitance. Refer to the document linked to
this web address: www.semiconductors.philips.com/acrobat/literature/9398/39340011.pdf.
Note 10:The idle time begins from the initiation of the stop pulse.
