DAC 4-CH Resistor-String 8-bit 16-Pin QSOP

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. The MAX5105/MAX5106 feature a software-controlled 10µA shutdown mode and a mute state that drives the DAC outputs to their respective REFL_ voltages. The MAX5105 includes an asynchronous MUTE input, as well as a RDY/BSY-bar output that indicates the status of the nonvolatile memory. The MAX5105 is available in 20-pin QSOP and 20-pin wide SO packages, and the MAX5106 is available in a 16-pin QSOP package.
