General Desc ription
The MAX5122/MAX5123 low-power, 12-bit, voltage-out-
put, digital-to-analog converters (DACs) feature an inter-
nal precision bandgap reference and output amplifier.
The MAX5122 operates on a single +5V supply with an
internal +2.5V reference, and offers a configurable output
amplifier. If necessary, the user can override the on-chip,
<10ppm/°C voltage reference with an external reference.
The MAX5123 has the same features as the MAX5122 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 con-
figurations, remote sensing, and high output drive capa-
bility 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 midscale and reduces output
glitches during power-up.
The serial interface is compatible with SPI, QSPI, and
MICROWIRE , which makes the MAX5122/MAX5123
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-compatible
14-bit upgrades, see the MAX5171/MAX5173 data sheet;
for the pin-compatible 13-bit version, see the MAX5132/
MAX5133 data sheet.
