19-5035; Rev 0; 10/09 TION KIT EVALUA BLE IL AVA A Dual 256-Tap, Volatile, Low-Voltage Linear Taper Digital Potentiometers Features S Dual 256-Tap Linear Taper Positions S Single +1.7V to +5.5V Supply Operation S Low 12µA Quiescent Supply Current S 10kI, 50kI, and 100kI End-to-End Resistance General Description The MAX5391/MAX5393 dual 256-tap, volatile, lowvoltage 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 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 MAX5391/MAX5393 make the devices uniquely suitable for the portable consumer market, battery backup industrial applications, and the automotive market. The MAX5391/MAX5393 include two digital potentiometers in a voltage-divider configuration. The MAX5391/ MAX5393 are specified over the -40NC to +125NC automotive temperature range and are available in a 16-pin, 3mm x 3mm TQFN and a 14-pin TSSOP package, respectively.
