Overview
The AD5570ARS-REEL is a single 16-bit serial input, voltage output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This device operates from supply voltages of ±11.4 V up to ±16.5 V, making it versatile for various high-voltage applications. The AD5570 features high accuracy with integral linearity (INL) and differential nonlinearity (DNL) accurate to 1 LSB. It includes on-board reference buffers, which eliminate the need for external components such as inverters, precision amplifiers, and resistors, thereby reducing the overall solution size and cost.
