ИС, цифровые потенциометры MAX5388NAUB+

Энергозависимый цифровой потенциометр , 100 кОм, Двойной, SPI, Линейный, ± 25%, 2.6 В

The MAX5388NAUB+ from Maxim Integrated Products is a dual, 256 tap, volatile, low voltage linear taper digital potentiometer in 10 pin µMAX 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 one 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.
