General Desc ription
The MAX5120/MAX5121 are low-power, 12-bit, voltage-
output digital-to-analog converters (DACs) with an inter-
nal precision bandgap reference and an output amplifier.
The MAX5120 operates on a +5V supply with an internal
amplifier reference of +2.5V and is capable of a +4.095V
full-scale output range. The MAX5121, operating on +3V,
delivers its +2.0475V full-scale output with an internal
precision reference of +1.25V. If necessary, the user can
override the internal, <10ppm/°C voltage reference with
an external reference. Both devices draw only 500μA of
supply current, which reduces to 3μA in power-down
mode. In addition, their power-up reset feature allows for
a user-selectable initial output state of either 0V or mid-
scale and minimizes output voltage glitches during
power-up.
The serial interface is compatible with SPI , QSPI
and MICROWIRE , which makes the MAX5120/
MAX5121 suitable for cascading multiple devices. Each
DAC has a double-buffered input organized as an input
register followed by a DAC register. A 16-bit shift regis-
ter loads data into the input register. The DAC register
may be updated independently or simultaneously with
the input register.
Both devices are available in a 16-pin QSOP package
and are specified for the extended industrial (-40°C to
+85°C) temperature range. For pin-compatible 14-bit
upgrades, see the MAX5170/MAX5172 data sheet;
for pin-compatible 13-bit versions, see the MAX5130/
MAX5131 data sheet.
