The MAX5391/MAX5393 dual 256-tap, volatile, low-
voltage linear taper digital potentiometers offer three
end-to-end resistance values of 10kI, 50kI, and 100kI.
Operating from a single +1.7V to +5.5V power sup-
ply, these devices provide a low 35ppm/NC end-to-end
temperature coefficient. The devices feature an SPIK
interface.
The small package size, low supply voltage, low sup-
ply current, and automotive temperature range of the
MAX5391/MAX5393 make the devices uniquely suitable
for the portable consumer market, battery backup indus-
trial applications, and the automotive market.
The MAX5391/MAX5393 include two digital potentio-
meters in a voltage-divider configuration. The MAX5391/
MAX5393 are specified over the -40NC to +125NC auto-
motive temperature range and are available in a 16-pin,
3mm x 3mm TQFN and a 14-pin TSSOP package,
respectively.
