High-performance DACs Reduce Board Space and Lower System Costs

Texas Instruments introduced a new family of digital-to-analog converters (DACs) that enables engineers to increase the accuracy and performance of programmable logic controller (PLC) I/O modules, field sensors and transmitters, and building automation systems, while decreasing overall system size and cost. The DAC8760 family is also the industry's first to provide simultaneous voltage and current outputs, giving system designers the flexibility to use either one or both outputs. Key benefits of the DAC8760 family:

Highest precision: Maximum total unadjusted error (TUE) of 0.1 percent, eliminating the need for calibration.

Highest integration for reduced board space and bill of materials: Each device in the family includes voltage output, 4- to 20-mA output, precision reference and low-dropout regulator (LDO), along with on-chip reliability and diagnostics via a watchdog timer and cyclic redundancy check.

Greater design flexibility: Designers can program the ranges for voltage and current outputs using the serial peripheral interface (SPI).

Widest temperature range: Supports temperatures ranging from -40 to +125ËšC, 32 percent wider than similar DACs.

Evaluation modules (EVMs) are available for each device in the DAC8760 family, providing an easy way to evaluate device performance and operating characteristics. This includes an enhanced EVM, which features additional components to increase immunity from electrostatic discharge (ESD) and electromagnetic interference (EMI) events. An IBIS model to perform various board-level signal integrity simulations and timing analyses is also available.
