The DAC8760 family is also the industry’s first to provide simultaneous voltage and current outputs, giving you flexibility to use either one or both outputs. Features inlcude;

  1. Highest precision: Maximum total unadjusted error (TUE) of 0.1%, eliminating the need for calibration;
  2. 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;
  3. Greater design flexibility: Designers can program the ranges for voltage and current outputs using the serial peripheral interface (SPI);
  4. Widest temperature range: Supports temperatures ranging from -40 to +125˚C, 32 percent wider than similar DACs.

Support tools for the DAC8760 family include reference designs, simulation models and hardware evaluation modules. Reference design circuits provide theory, simulation, calculation, design methodology and more, examples include;

  1. Combined Voltage and Current Output Terminal for Analogue Outputs (AO) in Industrial Applications (TIPD119);
  2. Single-Channel Industrial Voltage and Current Output Driver, Isolated, EMC/EMI Tested (TIPD153);
  3. 16-Bit Analogue Output Module Reference Design for Programmable Logic Controllers (TIDA-00118).

Evaluation modules (EVMs) include 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.
