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.
