MAX5389
Dual, 256-Tap, Volatile, Low-Voltage
Linear Taper Digital Potentiometer
19-5141; Rev 2; 11/10
General Description
The MAX5389 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 MAX5389 features an up/down interface.
The small package size, low supply operating voltage,
low supply current, and automotive temperature range
of the MAX5389 make the device uniquely suited for the
portable consumer market, battery backup industrial
applications, and the automotive market.
The MAX5389 is specified over the automotive -40NC to
+125NC temperature range and is available in a 14-pin
TSSOP package.
