MAX544 - +5V / Serial-Input / Voltage-Output / 14-Bit DACs

Description

The MAX544/MAX545 are serial-input, voltage-output, 14-bit digital-to-analog converters (DACs) that operate from a single +5V supply.

They provide 14-bit performance (±0.5LSB INL and ±0.9LSB DNL) over temperature without any adjustments.

19-1088; Rev 3; 12/99 +5V, Serial-Input, Voltage-Output, 14-Bit DACs General Description The MAX544/MAX545 are serial-input, voltage-output, 14-bit digital-to-analog converters (DACs) that operate from a single +5V supply. They provide 14-bit performance (±0.5LSB INL and ±0.9LSB DNL) over temperature without any adjustments. The DAC output is unbuffered, resulting in a low supply current of 0.3mA and a low offset error of 0.6mV. The DAC output range is 0V to VREF. For bipolar operation, matched scaling resistors are provided in the MAX545 for use with an external precision op amp (such as the MAX400), generating a ±V REF output swing. The MAX545 also includes Kelvin-sense connections for the reference and analog ground pins to reduce layout sensitivity.
