Product Overview

The AD5421BREZ is a 1-channel 16-bit Serial Input Loop-powered DAC designed to meet the needs of smart transmitter manufacturers in the industrial control industry. The DAC provides a high precision and fully integrated solution. It includes a regulated voltage output that is used to power itself and other devices in the transmitter. This regulator provides a regulated 1.8V to 12V output voltage. It also contains 1.22V and 2.5V references, thus eliminating the need for a discrete regulator and voltage reference. It can be used with standard HART® FSK protocol communication circuitry without any degradation in specified performance. The high speed serial interface is capable of operating at 30MHz and allows for simple connection to commonly used microprocessors and microcontrollers via a SPI-compatible, 3-wire interface.
  • 16-bit Resolution and monotonicity
