MAX5393MAUD+

The MAX5393MAUD+ is a dual, 256 tap, volatile, low voltage linear taper digital potentiometer in 14 pin TSSOP package. This device provides a low 35ppm/°C end to end temperature coefficient and features an SPI interface. The small package size, low supply voltage, low supply current and automotive temperature range of the MAX5388 make the devices uniquely suitable for the portable consumer market and battery backup industrial applications. It includes two digital potentiometer in a voltage divider configuration and one digital potentiometer in a variable-resistor configuration. Ideally used at low voltage battery applications, portable electronics, mechanical potentiometer replacement, offset and gain control and adjustable voltage references/linear regulators.
