AD3542R Dual Channel, 16-Bit, 16 MUPS, Multispan, Multi-IO SPI DAC
●The AD3542Ris a low drift, dual channel, ultra-fast, 16-bit accuracy, voltage output digital-to-analog converter (DAC) that can be configured in multiple voltage span ranges. The AD3542Roperateswith a fixed 2.5 V reference.
●The device incorporates three drift compensating feedback resistors for the internal 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 −2.5 V to +7.5 V.
●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 single SPI (classic SPI) mode, dual SPI mode and synchronous dual 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 AD3542Ris specified over the extended industrial temperature range (–40°C to +105°C).
