DEMO-AD7124-DZ

DEMO-AD7124-DZ is a demonstration board for the CN0382 isolated 4mA to 20mA/HART transmitter. The CN0382 circuit uses the AD7124-4, an ultralow power, precision 24-bit, Σ-Δ analogue-to-digital converter (ADC), which includes all the features needed for temperature and pressure systems. The circuit also includes the AD5421, a 16-bit, 4mA to 20mA, loop powered digital-to-analogue converter (DAC); the AD5700, the industry’s lowest power and smallest footprint HART compliant IC modem; the ADuM1441, which provides ultralow power serial peripheral interface (SPI) isolation; the ADG5433 CMOS switch; and the ADP162 low power, 3.3V regulator in the isolated power circuitry.
