GENERAL DESCRIPTION

The AD3541R is a low drift, single channel, ultra-fast, 16-bit accuracy,

voltage output digital-to-analog converter (DAC) that can be

configured in multiple voltage span ranges. The AD3541R 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. The AD3541R has five preconfigured output ranges:

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 or 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 AD3541R is specified over the extended industrial temperature

range (–40°C to +105°C).
