Product Details

The AD5755-1 is a quad, voltage and current output DAC, that operates with a power supply range from -26.4 V to +33 V. On chip dynamic power control minimizes package power dissipation in current mode. This is achieved by regulating the voltage on the output driver from between 7.4 V to 29.5 V using a dc-to-dc boost converter optimized for minimum on-chip power dissipation. Each channel has a corresponding CHART pin so that HART signals can be coupled onto the current output of the AD5755-1.

The part uses a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI, QSPI™, MICROWIRE™, DSP and microcontroller interface standards. The interface also features optional CRC-8 packet error checking, as well as a watchdog timer that monitors activity on the interface.

Product Highlights

  1. Dynamic power control for thermal management.
  2. 16-bit performance.
  3. Multichannel.
  4. HART compliant.
