General Desc ription
The MAX5132/MAX5133 low-power, 13-bit, voltage-out-
put digital-to-analog converters (DACs) feature an inter-
nal precision bandgap reference and output amplifier.
The MAX5132 operates on a single +5V supply with an
internal reference of +2.5V and offers a configurable out-
put amplifier. If necessary, the user can override the on-
chip, <10ppm/°C voltage reference with an external
reference. The MAX5133 has the same features as the
MAX5132 but operates from a single +3V supply and
has an internal +1.25V precision reference. The user-
accessible inverting input and output of the amplifier
allows specific gain configurations, remote sensing, and
high output drive capability for a wide range of
force/sense applications. 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 reduces output glitches during power-up.
The serial interface is compatible with SPI , QSPI ,
and MICROWIRE , which makes the MAX5132/
MAX5133 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 register
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) operating temperature range. For pin-compati-
ble 14-bit upgrades, see the MAX5171/MAX5173 data
sheet; for pin-compatible 12-bit versions, see the
MAX5122/MAX5123 data sheet.
