Overview
The AD5546BRUZ from Analog Devices Inc. is a precision 16-bit digital-to-analog converter (DAC) designed for high-performance applications. This device is part of the AD5546/AD5556 family, which includes both 16-bit and 14-bit versions. The AD5546 operates from a single 2.7 V to 5.5 V supply and features a current output with parallel input, making it suitable for a variety of precision conversion tasks.
The DAC is built with an R-2R architecture and includes built-in resistors for four-quadrant bipolar applications, facilitating outputs in the range of 0 V to –10 V, 0 V to +10 V, or ±10 V. The device also includes a feedback resistor (RFB) to simplify current-to-voltage conversion with an external buffer.
