MAX5105集成电路（IC）的数模转换器（DAC）规格书PDF中文资料

General Description

The MAX5105/MAX5106 nonvolatile, quad, 8-bit digital-to-analog converters (DACs) operate from a single +2.7V to +5.5V supply. An internal EEPROM stores the DAC states even after power is removed. Data from these nonvolatile registers automatically initialize the DAC outputs and operating states during power-up. Precision internal buffers swing Rail-to-Rail®, and the reference input range includes both ground and the positive rail.
