GENERAL DESCRIPTION

The AD3542R is 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 AD3542R operates

with 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 AD3542R is specified over the extended industrial temperature

range (–40°C to +105°C).
