AD5570WRSZ Datasheet PDF - ADI

●The AD5570WRSZ is a single 16-bit serial input voltage output Digital-to-analog Converter (DAC) operates from supply voltages of ±11.4 to ±16.5V. Integral linearity and differential nonlinearity are accurate to 1LSB. During power-up, when the supply voltages are changing, VOUT is clamped to 0V via a low impedance path. The AD5570 DAC comes complete with a set of reference buffers. The reference buffers allow a single, positive reference to be used. The voltage on REFIN is gained up and inverted internally to give the positive and negative reference for the DAC core. Having the reference buffers on-chip eliminates the need for external components such as inverters, precision amplifiers and resistors, thereby reducing the overall solution size. The AD5570 uses a versatile 3-wire interface that is compatible with SPI®, QSPI™, MICROWIRE™ and DSP® interface standards. Data is presented to the part as a 16-bit serial word. Serial data is available on the SDO pin for daisy-chainin
