MAXIM INTEGRATED PRODUCTS  MAX531AESD+  数模转换器, 精准, 12 bit, 串行, 4.5V 至 5.5V, NSOIC, 14 引脚

The is a +5V, low power, voltage output, serial 12bit digital to analogue converter DAC in 14 pin NSOIC package. It uses an "inverted" R-2R ladder network with a single supply CMOS op-amp to convert 12bit digital data to analogue voltage levels. This device use a three-wire serial interface that is compatible with SPI, QSPI CPOL = CPHA = 0 and Microwire standards. This DAC is specified for single +5V power supply operation and can also be operated with ±5V supplies. The internal op-amp can be configured for a gain of +1 or +2 as well as for unipolar or bipolar output voltages. The device can also be used as a four quadrant multiplier without external resistors or op-amps. It is trimmed for offset voltage, gain and linearity.
