Maxim Integrated MAX5306EUE

Description
The MAX5306/MAX5307 are low-power, low-glitch, octal 12-bit voltage-output digital-to-analog converters (DACs) in a compact 16-pin TSSOP package. They operate with a wide supply voltage range of 2.7V to 5.5V and consume less than 215µA (max) supply current per DAC, making them suitable for low-power and low-voltage applications. The low 2nV/s glitch energy minimizes digital-noise feedthrough from the digital inputs to the outputs.
The MAX5306 features a digital output (DOUT) for daisy-chaining multiple devices, while the MAX5307 has a hardware reset input (CLR) to clear all registers and DACs to zero. Both devices have a software shutdown feature that reduces the supply current to 1μA. The loadDAC (LDAC) function updates the output of all eight DACs simultaneously.
The 3-wire SPI, QSPI, MICROWIRE, and DSP-compatible serial interface allows for independent or simultaneous updates of the input and DAC registers with a single software command. The double-buffered design minimizes digital-noise feedthrough from the digital inputs to the outputs.
