Overview
19-1925; Rev 1; 6/01 Nonvolatile, Quad, 8-Bit DACs General Description The MAX5105/MAX5106 nonvolatile, quad, 8-bit digitalto-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 output that indicates the status of the nonvolatile memory.
The MAX5105 is available in a 20-pin QSOP and 20-pin wide SO packages, and the MAX5106 is available in a 16-pin QSOP package.
