Overview
The AD5570WRSZ, produced by Analog Devices Inc., is a single 16-bit serial input, voltage output Digital-to-Analog Converter (DAC). This device operates from supply voltages ranging from ±11.4 V to ±16.5 V, making it versatile for various high-voltage applications. The AD5570 is known for its high accuracy, with integral linearity (INL) and differential nonlinearity (DNL) accurate to 1 LSB. It features a power-on reset circuit that ensures the DAC output powers up to 0 V, and it includes on-chip reference buffers that eliminate the need for external components such as inverters, precision amplifiers, and resistors.
