The MAX5386/MAX5388 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 +2.6V to +5.5V power supply 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 supply current, and automotive temperature range of the MAX5386/MAX5388 make the devices uniquely suitable for the portable consumer market, battery backup industrial applications, and the automotive market. The MAX5386 includes two digital potentiometers in a voltage-divider configuration. The MAX5388 includes one digital potentiometer in a voltage-divider configuration and one digital potentiometer in a variable-resistor configuration. The MAX5386/MAX5388 are specified over an extended -40NC to +125NC temperature range and are available in 16-pin, 3mm x 3mm TQFN or 10-pin, 3mm x 5mm FMAXM packages, respectively.
