MAX5115, MAX5116
Nonvolatile, Quad, 8-Bit DACs with 2-Wire Serial Interface
|
Status
Active: In Production.
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. The reference rails accept voltage inputs that range from ground to the positive supply rail.
The devices operate from a single +2.7V to +5.25V supply and consume 200µA per DAC. A software-controlled power-down mode decreases supply current to less than 25µA. A software-controlled mute mode sets each DAC, or both DACs simultaneously, to their respective REFL_ voltages. The MAX5116 also includes an asynchronous active-low MUTE input, that drives all DAC outputs simultaneously to their respective REFL_ voltages.
The MAX5115 is available in a 20-pin QSOP, and the MAX5116 is available in a 16-pin QSOP package. Both devices are specified for operation over the extended (-40°C to +85°C) temperature range.
