MAX5478

Dual, 256-Tap, Nonvolatile, I2C-Interface, Digital Potentiometers

General Description The MAX5477/MAX5478/MAX5479 nonvolatile, dual, linear-taper, digital potentiometers perform the function of a mechanical potentiometer, but replace the mechanics with a simple 2-wire digital interface. Each device performs the same function as a discrete potentiometer or var

MAX5478

双路、256抽头、非易失、I²C接口、数字电位器

MAX5477/MAX5478/MAX5479非易失、双路、线性变化的数字电位器具有与机械电位器相同的功能,但是,能够以简单的2线数字接口取代了机械调节。每个器件都具有与分立电位器或可变电阻相同的功能,提供256个抽头点。\n\n 器件具有内部非易失EEPROM,用来存储上电初始化时的滑动端位置。写保护功能避免对EEPROM的意外写入。快速模式、I²C兼容的串行接口可以以400kbps的速率进行数据通信,节省了电路板空间并降低了多种应用相互连接的复杂度。三个地址输入端提供8个地址选择。\n\n MAX5477/MAX5478/MAX5479有3个额定电阻值:10kΩ (MA • 上电时从非易失存储器调入滑动端位置\n• EEPROM写保护\n• 微小的3mm x 3mm x 0.8mm薄型QFN封装\n• 70ppm/°C端到端电阻温度系数\n• 10ppm/°C比例温度系数\n• 400kbps快速I²C串行接口\n• 1µA (最大值)静态电流\n• 单电源工作:+2.7V至+5.25V\n• 每个电位器具有256个抽头\n• 分压模式下具有±0.5 LSB DNL\n• 分压模式下具有±1 LSB INL\n• 可提供评估板;
