Overview
The AD5552BR, produced by Analog Devices Inc., is a single, 14-bit, serial input, voltage output Digital-to-Analog Converter (DAC). It operates from a single supply voltage ranging from 2.7 V to 5.5 V, making it versatile for various applications. The DAC provides 14-bit performance without any adjustments and features an unbuffered output to reduce power consumption and offset errors. The AD5552BR can be operated in bipolar mode with an external op-amp, generating a ±VREF output swing. It also includes Kelvin sense connections for the reference and analog ground pins to enhance precision and reduce layout sensitivity.
