The AD3552R 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 synchronous 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 AD3552R is specified over the extended industrial temperature range (–40°C to +105°C). Table 1.

Analog Devices is in the process of updating documentation to provide terminology and language that is culturally appropriate. This is a process with a wide scope and will be phased in as quickly as possible. Thank you for your patience. |
