MAX544BCPA+

The MAX544BCPA+ is a serial input, voltage output, 14bit digital to analogue converter (DAC) in 8 pin DIP package. This single channel DAC operates from a single +5V supply and provides 14bit performance (±0.15LSB INL and ±0.15LSB DNL) over temperature without any adjustments. The DAC output is unbuffered resulting in a low supply current of 0.3mA and low offset error of 0.6mV. A 16bit serial word is used to load data into the DAC latch. The 10MHz, 3-wire serial interface is compatible with SPI/QSPI/MICROWIRE and it also interfaces directly with optocouplers for applications requiring isolation. A power-on reset circuit clears the DAC output to 0V (unipolar mode) when power is initially applied. The MAX544B is used in digital offset and gain adjustment, automated test equipment and data acquisition systems.
