MAX5386MATE+T
Dual, 256-Tap, Volatile Low-Voltage Linear Taper Digital Potentiometers
General Description
The MAX5386/MAX5388 dual, 256-tap, volatile, low- volt-
age linear taper digital potentiometers offer three end-to-end resistance values of 10kΩ, 50kΩ, and 100kΩ. Operating from a single +2.6V to +5.5V power supply
these devices provide a low 35ppm/°C end-to-end tem-perature coefficient. The devices feature an SPI interface.
The small package size, low supply voltage, low sup-ply current, and automotive temperature range of the MAX5386/MAX5388 make the devices uniquely suitable for the portable consumer market and battery-backup industrial applications.
The MAX5386 includes two digital potentiometers in a voltage-divider configuration. The MAX5388 includes
one digital potentiometer in a voltage-divider configura-tion and one digital potentiometer in a variable-resistor configuration. The MAX5386/MAX5388 are specified over
an extended -40°C to +125°C temperature range and are available in 16-pin, 3mm x 3mm TQFN or 10-pin, 3mm x
5mm µMAX® packages, respectively.

Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Electrical Characteristics
(VDD = +2.6V to +5.5V, VH_ = VDD, VL_ = GND, TA = TMIN to TMAX, unless otherwise noted. Typical values are at VDD = +5V,
TA = +25˚C. ) (Note 1)
Note 1: All devices are 100% production tested at TA = +25°C. Specifications over temperature limits are guaranteed by design and characterization.
Note 2: DNL and INL are measured with the potentiometer configured as a voltage-divider (Figure 1) with H = VDD and L = GND. The wiper terminal is unloaded and measured with an ideal voltmeter.
Note 3: R-DNL and R-INL are measured with the potentiometer configured as a variable resistor (Figure 1). DNL and INL are mea-sured with the potentiometer configured as a variable resistor. H_ is unconnected and L_ = GND. For VDD = +5V, the wiper terminal is driven with a source current of 400μA for the 10kΩ configuration, 80μA for the 50kΩ configuration, and 40μA for the 100kΩ configuration. For VDD = +2.6V, the wiper terminal is driven with a source current of 200μA for the 10kΩ configu-ration, 40μA for the 50kΩ configuration, and 20μA for the 100kΩ configuration.
Note 4: The wiper resistance is the worst value measured by injecting the currents given in Note 3 in to W with L = GND. RW = (VW- VH)/IW.
Note 5: Drive HA with a 1kHz GND to VDD amplitude tone. LA = LB = GND. No load. WB is at midscale with a 10pF load. Measure WB.
Note 6: The wiper-settling time is the worst case 0 to 50% rise time, measured between tap 0 and tap 127. H = VDD, L = GND, and the wiper terminal is loaded with 10pF capacitance to ground.
Note 7: Digital timing is guaranteed by design and characterization, not production tested.
