MAX5105 - 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.

Key Features

  • o On-Chip EEPROM Stores DAC States o Power-On Reset Initialization of All Registers to Prestored States o +2.7V to +5.5V Single-Supply Operation o Four 8-Bit DACs with Independent High and Low Reference Inputs (MAX5105) o Ground to VDD Reference Input Range o Rail-to-Rail Output Buffers o Low 1mA Supply Current o Low Power 10µA (max) Shutdown Mode o Small 20- or 16-Pin QSOP Package o SPI™/QSPI™/.

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.
