MAX5394
Single, 256-Tap Volatile, SPI, Low-Voltage Linear
Taper Digital Potentiometer
General Description
The MAX5394 single, 256-tap volatile, low-voltage
linear taper digital potentiometer offers three end-to-
end resistance values of 10k
, 50k, and 100k.
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, mid-
code, full-code, or the value contained in the wiper
register. Ultra-low-quiescent supply current (< 1A) 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.
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, battery-backup industrial
applications, and automotive market.
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.
