NAFE33352-EVB

NAFE33352-EVB is a software configurable universal AIO-AFE evaluation board. It is designed to test NAFE33352, which is a software-configurable universal analogue input and output (AIO) analogue front-end (AFE) that meets high-precision measurement and control requirements of industrial-grade applications. NAFE33352’s highly integrated and innovative system architecture includes precision 14/16/18-bit DAC and a 16/24-bit ADC, a low-drift voltage reference, low-offset drift buffers and high-voltage and high-precision amplifiers with a 70V input-protection circuit for EMC and miswiring scenarios, enabling true software configurable universal analogue inputs and outputs. This evaluation board, along with the LPC54S018 MCU (with custom firmware) board, provides an easy-to-use evaluation platform.

• ±36V protected I/O (external transient voltage suppressor required for output)
• Short circuit protection on both input and output
• Supply voltage range from ±7V to ±28V
• Two universal inputs
• EMC compliant and ready-to-use complete hardware design
• Easy-to-use evaluation platform with GUI
• Channel configurations: ranges: ±12.5V, ±25mA, 1mohm-1Mohm I/O
• Factory calibration or user calibration options
• ±0.01% accuracy at room and ±0.08% accuracy overtemperature (after room calibration)
• Temperature range from -40°C to 125°C
