Product Details

The AD3552R is a low drift, ultra-fast, 16-bit accuracy, current output digital-to-analog converter (DAC) that can be configured in multiple voltage span ranges. The AD3552R operates with a fixed 2.5 V reference.

The device 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 SPI interface can be configured in single SPI (classic SPI) mode, dual SPI mode, synchronous dual SPI mode, and quad SPI mode with single date rate (SDR) or double data rate (DDR), with logical levels from 1.2 V to 1.8 V.

To improve device robustness, cyclic redundancy check (CRC) can be enabled. Multiple error checkers have also been integrated to detect VREF failures or memory map corruption.

The AD3552R is specified over the extended industrial temperature range (–40°C to +105°C).
