Overview
The AD5691RBCPZ-RL7 is a 12-bit, single-channel, buffered voltage output Digital-to-Analog Converter (DAC) from Analog Devices Inc. It is part of the nanoDAC+ family, known for its low power consumption and high precision. This device operates from a single 2.7 V to 5.5 V supply and features an internal 2.5 V reference with a low drift of 2 ppm/°C. The AD5691RBCPZ-RL7 is available in an 8-lead LFCSP (2mm x 2mm) package, making it suitable for space-constrained applications.
