The AD5551 and AD5552 are single, 14-bit, serial input, voltage output DACs that operate from a single 5 V 10% supply. The AD5551 and AD5552 utilize a versatile 3-wire interface that is compatible with SPI, QSPI, MICROWIRE, and DSP interface standards. These DACs provide 14-bit performance without any adjustments. The DAC output is unbuffered, which reduces power consumption and offset errors contributed by an output buffer.
