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

Description

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.

Features

  • Nonvolatile Registers Initialize DACs to Stored States.
  • +2.7V to +5.25V Single-Supply Operation.
  • Quad 8-Bit DACs with Independent High and Low Reference Inputs.
  • Rail-to-Rail Output Buffers.
  • Low 200µA per DAC Supply Current.
  • Power-Down Mode Reduces Supply Current to 25µA (max).
  • 400kHz, I2C-Compatible, 2-Wire Serial Interface.
  • Asynchronous MUTE Input (MAX5116).
  • Small 16-/20-Pin QSOP Packages MAX5115/MAX5116 Orderin.

19-3586; Rev 0; 2/05 www.DataSheet4U.com Nonvolatile, Quad, 8-Bit DACs with 2-Wire Serial Interface General Description 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-wire serial interface allows for a maximum clock frequency of 400kHz. The MAX5115 has independent high and low reference inputs allowing maximum output voltage range flexibility. The MAX5116 has single high and low reference inputs for all DACs to minimize trace count and save board space.
