MAXREFDES38#

MAXREFDES38# is an ECT/EPT current fault sensor evaluation kit. The ECT/EPT is a low-power sensor that may be placed at many points in the grid thereby increasing the granularity grid health data and fault location. It features a low-power, 16-bit, high-accuracy, 3-ch analogue I/P. Input channels can be configured as ±3VP-P single-ended or ±6VP-P differential. The MAXREFDES38# design integrates a 3-ch analogue switch (MAX14531E), a quad precision low-power buffer (MAX44245), a 16-bit fully differential ADC (MAX11901), an ultra-high-precision, 3V voltage reference (MAX6126), a low-noise precision op amp (MAX44241), a STM32L1 microcontroller; a supervisory circuit (MAX16058), a 64KB SRAM, a FTDI USB-UART bridge, a dual-output step-down DC-DC converter (MAX1775), a switched-capacitor voltage converter (MAX1044) and -3V, 1.8V, 3.3V, 3.38V, 4.5V power rails (MAX1735/ MAX8891/ MAX8881/ MAX8902B/ MAX16910).

• High accuracy
• Accepts 3VP-P single-ended signal or 6VP-P differential signal
• Optimized layout and size
• Example C source code
• Test data and device drivers
• Entire sys typically operates at less than 85mW and fits in a space roughly size of a credit card
