The AD3551R is a low drift, single channel, ultra-fast, 16-bit accuracy, current output digital-to-analog converter (DAC) that can be configured in multiple voltage span ranges. The AD3551R operates with a fixed 2.5 V reference.
Each DAC incorporates three drift compensating feedback resistors for the required external transimpedance amplifier (TIA) that scales the output voltage. Offset and gain scaling registers allow for generation of multiple output span ranges, such as 0 V to 2.5 V, 0 V to 5 V, 0 V to 10 V, −5 V to +5 V, and −10 V to +10 V, and custom intermediate ranges with full 16-bit resolution.
The DAC can operate in fast mode for maximum speed or precision mode for maximum accuracy.
The serial peripheral interface (SPI) can be configured in quad SPI mode, dual SPI mode, and single SPI (classic SPI) mode with single date rate (SDR) or double data rate (DDR), with logical levels from 1.2 V to 1.8 V.
The AD3551R is specified over the extended industrial temperature range (–40°C to +105°C).
