MAX5115 - Maxim

MAX5115 Nonvolatile - Quad 8-Bit DACs with 2-Wire Serial Interface

The MAX5115/MAX5116 quad, 8-bit, digital-to-analog converters (DACs) feature nonvolatile registers. These nonvolatile registers store the DAC operating modes and output states, allowing the DACs to initialize to specified configurations at power-up. Precision on-chip output buffers swing rail-to-rail, and provide 8µs settling time. The I2C*-compatible, 2-wir.
