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

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.
