32抽头FleaPoT™、2线数字电位器

业内尺寸最小的数字电位器

产品详情

The MAX5460–MAX5468 linear-taper digital potentiometers perform the same function as a mechanical potentiometer or a variable resistor. These devices consist of a fixed resistor and a wiper contact with 32-tap points that are digitally controlled through a 2-wire serial interface. The MAX5462/MAX5465/MAX5468 are configured as potentiometers. The rest of the devices in this family are configured as variable resistors. See Pin Configurations for part functionality.

Three resistance values are available: 10kΩ (MAX5466/ MAX5467/MAX5468), 50kΩ (MAX5463/MAX5464/ MAX5465), and 100kΩ (MAX5460/MAX5461/MAX5462). The MAX5460–MAX5465 (100kΩ and 50kΩ) are available in space-saving 5-pin and 6-pin SC70 packages. The MAX5466/MAX5467/MAX5468 (10kΩ) are available in 5-pin and 6-pin SOT23 packages.
