Product Overview

The AD421BRZ is a complete loop-powered Digital-to-analog Converter (DAC) designed to meet the needs of smart transmitter manufacturers in the Industrial Control industry. It provides a high precision, fully integrated. The AD421 is ideal for extending the resolution of smart 4 to 20mA transmitters. This regulator provides either 5/3.3/3V regulated output voltage. The part also contains 1.25 and 2.5V precision references. The AD421 thus eliminates the need for a discrete regulator and voltage reference. The only external components required are a number of passive components and a pass transistor to span large loop voltages. The AD421 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 10Mbps and allows for simple connection to commonly-used microprocessors and microcontrollers via a standard three-wire serial interface.
  • HART® Compatible
  • Programmable alarm current capability
  • Flexible high speed serial interface
  • 750µA Quiescent current max
