Low-Cost, Voltage-Output, 16-Bit DACs with Internal Reference in µMAX

The MAX5200-MAX5203 serial input, voltage-output, 16-bit digital-to-analog converters (DACs) provide monotonic 16-bit output over temperature without any adjustments. The MAX5200/MAX5201 operate from a +5V single power supply featuring a +2.5V internal reference and an internal gain of 2, while the MAX5202/MAX5203 operate from a +3V or +3.3V single power supply featuring a +1.5V internal reference and an internal gain of 2. The MAX5200-MAX5203 DAC output range is typically 0 to VDD.

The MAX5200-MAX5203 feature a hardware reset input (active-low CLR) that, when pulled low, clears the output to zero code 0000 hex (MAX5201/MAX5203) or resets the output to midscale code 8000 hex (MAX5200/MAX5202).

The 3-wire serial interface is SPI™/QSPI™/MICROWIRE™ compatible. All devices have a low-power shutdown mode that reduces the supply current consumption to 1µA.

The MAX5200-MAX5203 are available in a space-saving 10-pin µMAX® package and are guaranteed over the extended temperature range (-40°C to +105°C). Refer to the MAX5204-MAX5207 data sheet for external reference versions.
