MAX5544 Datasheet | Maxim Integrated

Description The MAX5544 serial-input, voltage-output, 14-bit monotonic digital-to-analog converter (DAC) operates from a single +5V supply. The DAC output is unbuffered, resulting in low 0.3m A supply current and low 1LSB offset error. The DAC output range is 0V to VREF. The DAC latch accepts a 16-bit serial word. A power-on reset circuit clears the DAC output to 0V (unipolar mode) when power is initially applied. The 10MHz 3-wire serial interface is SPI™/QSPI™/ MICROWIRE™ patible and interfaces directly with optocouplers for applications requiring isolation. The MAX5544 is available in an 8-pin SO package. o +5V Single-Supply Operation o Low Power: 1.5m W o 1µs Settling Time o Unbuffered Voltage Output Directly Drives 60kΩ Loads o SPI/QSPI/MICROWIRE-patible Serial Interface o Power-On Reset Circuit Clears DAC Output to 0V (unipolar mode) o Schmitt Trigger Inputs for Direct Optocoupler Interface Features o Full 14-Bit Performance Without Adjustments Applications High-Resolution Offset and Gain Adjustment Industrial Process Control Automated Test Equipment Data Acquisition Systems PART MAX5544CSA MAX5544ESA Ordering Information TEMP.
