Product Description

Product Details
The AD5570 is a single 16-bit serial input, voltage output DAC that operates from supply voltages of ±11.4 V up to ±16.5 V. Integral linearity (INL) and differential nonlinearity (DNL) are accurate to 1 LSB. During power-up, when the supply voltages are changing, VOUT is clamped to 0 V 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 and cost.
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-chaining purposes. Data readback allows the user to read the contents of the DAC register via the SDO pin.
Features on the AD5570 include LDAC which is used to update the output of the DAC. The device also has a power-down pin (PD), allowing the DAC to be put into a low power state, and a CLR pin that allows the output to be cleared to 0 V.
The AD5570 is available in a 16-lead SSOP.
