Overview
The AD5348BRU is a high-performance, 12-bit, octal digital-to-analog converter (DAC) produced by Analog Devices Inc. This device operates from a 2.5 V to 5.5 V supply and features a parallel interface for data input. The AD5348BRU is designed to provide high accuracy and reliability, making it suitable for a variety of applications requiring precise digital-to-analog conversion.
The device includes an on-chip output buffer that can drive the output to both supply rails and offers a choice of buffered or unbuffered reference inputs. It also features simultaneous update of DAC outputs via the LDAC pin, an asynchronous CLR facility, and power-on reset to 0 V. The AD5348BRU is available in a 38-lead TSSOP package and operates over a wide temperature range of -40°C to +105°C.
