MAX5394

Single, 256-Tap Volatile, SPI, Low-Voltage Linear

Taper Digital Potentiometer

General Description

Beneﬁts and Features

● Single Linear Taper 256-Tap Positions

The MAX5394 single, 256-tap volatile, low-voltage

linear taper digital potentiometer offers three end-to-

end resistance values of 10kΩ, 50kΩ, and 100kΩ.

Potentiometer terminals are independent of supply for

voltages up to 5.25V with single-supply operation from

1.7V to 5.5V (charge pump enabled). User-controlled

shutdown modes allow the H, W, or L terminal to be

opened with the wiper position set to zero-code, midcode,

full-code, or the value contained in the wiper register. Ultra-

low-quiescent supply current (< 1μA) can be achieved

for supply voltages between 2.6V and 5.5V by disabling

the internal charge pump and not allowing potentiometer

terminals to exceed the supply voltage by more than

0.3V. The MAX5394 provides a low 50ppm/°C end-to-end

temperature coefﬁcient and features a SPI serial interface.

● 10kΩ, 50kΩ, and 100kΩ End-to-End Resistance

● 1.7V to 5.5V Extended Single Supply

● 0 to 5.25V H, W, L Operating Voltage Independent of V

● 1μA (typ) Supply Current in Low-Power Mode

● ±1.0 LSB INL, ±0.5 LSB DNL (max) Wiper Accuracy

● Power-On Sets Wiper to Midscale

● 50ppm/°C End-to-End Temperature Coefficient

● 5ppm/°C Ratiometric Temperature Coefficient

● -40°C to +125°C Operating Temperature Range

● 2mm x 2mm, 8-Pin TDFN Package

● SPI-Compatible Serial Interface

The small package size, low operating supply voltage,

low supply current, and automotive temperature range

of the MAX5394 make the device uniquely suited for the

portable consumer market and battery-backup industrial

applications.

Applications

● Portable Electronics

● System Calibration

● Battery-Powered Systems

● Mechanical Potentiometer Replacement

The MAX5394 is available in a lead-free, 8-pin TDFN

(2mm x 2mm) package. The device operates over the

-40°C to +125°C automotive temperature range.
