AD3551R Digital-to-Analogue Converters (DACs)

Analog Devices Inc. AD3551R Digital-to-Analogue Converters (DACs) are low drift, 16-bit accuracy, current output DACs that can be configured in multiple voltage span ranges. These DACs incorporate three drift compensating feedback resistors for the required external trans-impedance amplifier (TIA) that scales the output voltage. The offset/gain scaling registers generate multiple output ranges like 0V to 2.5V, 0V to 5V, 0V to 10V, -5V to 5V, -10V to 10V, and custom intermediate ranges with 16-bit resolution. The AD3551R DACs feature a 33 MUPS rate in fast mode, 22 MUPS rate in precision mode, and 65ns small signal settling time to 0.1% accuracy. These DACs operate at 2.5V fixed reference, 5ns low latency, 10ppm/°C maximum temperature coefficient, and an industrial temperature range of -40°C to 105°C. Typical applications include instrumentation, process control equipment, medical devices, automated test equipment, data acquisition systems, optical communications, and programmable voltage sources.
