EVAALVUAAILTAIOBNLEKIT
Dual, 256-Tap, Volatile, Low-Voltage,
Linear Taper Digital Potentiometer
General Description
The MAX5392 dual, 256-tap, volatile, low-voltage, lin-
ear taper digital potentiometer offers three end-to-end
resistance values of 10kI, 50kI, and 100kI. Operating
from a single +1.7V to +5.5V power supply, the device
provides a low 35ppm/NC end-to-end temperature coef-
ficient. The device features an I²C interface.
The small package size, low supply operating voltage,
low supply current, and automotive temperature range
of the MAX5392 makes the device uniquely suited for
the portable consumer market, battery-backup industrial
applications, and the automotive market.
The MAX5392 is specified over the automotive -40NC to
+125NC temperature range and is available in a 16-pin
TSSOP package.
