MAX5387 双路、256抽头、易失、低电压线性变化数字电位器   概述 The MAX5387 dual, 256-tap, volatile, low-voltage linear taper digital potentiometer offers three end-to-end resistance values of 10kΩ, 50kΩ, and 100kΩ. Operating from a single +2.6V to +5.5V power supply, this device provides a low, 35ppm/°C end-to-end temperature coefficient. The device features an I²C interface.

The small package size, low supply operating voltage, low supply current, and automotive temperature range of the MAX5387 make the device uniquely suitable for the portable consumer market, battery backup industrial applications, and the automotive market.

The MAX5387 is specified over the automotive -40°C to +125°C temperature range and is available in a 14-pin TSSOP package.   关键特性
