“Current Source DAC AD5420 and Arduino UNO
Hello.In this article, I would like to share my experience with the AD5420 current digital-to-analog converter, which has the following characteristics:
16-bit resolution and monotonicity
Current output ranges: 4 mA to 20 mA, 0 mA to 20 mA, or 0 mA to 24 mA
±0.01% FSR typical total unadjusted error (TUE)
±3 ppm/°C typical output drift
Flexible serial digital interface
On-chip output fault detection
On-chip reference (10 ppm/°C maximum)
Feedback/monitoring of output current
Asynchronous clear function
Power supply (AVDD) range
10.8 V to 40 V; AD5410AREZ/AD5420AREZ
10.8 V to 60 V; AD5410ACPZ/AD5420ACPZ
Output loop compliance to AVDD − 2.5 V
Temperature range: −40°C to +85°C
For work, I took the following components:- Arduino UNO,- AD5420 shield for Arduino (with galvanic isolation),- Multimeter (for measuring the output current).”
