Dual, 256-Tap, Volatile, Low-Voltage
Linear Taper Digital Potentiometer
General Description
The MAX5387 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 +2.6V 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 MAX5387 make the device uniquely suitable for
the portable consumer market, battery backup industrial
applications, and the automotive market.
The MAX5387 is specified over the automotive -40NC to
+125NC temperature range and is available in a 14-pin
TSSOP package.
