Product Details

The MAX5216LPT evaluation kit (EV kit) enables evaluation of the loop-powered 4–20mA current-loop transmitter with the fault current-limiting capabilities and Highway Addressable Remote Transducer (HART) modem input/output ready, which utilizes the MAX5216 single-channel, low-power, buffered-output, 3-wire SPI interface 16-bit DAC, the MAX6133 3ppm/°C, low-power voltage reference, the MAX9620 single-channel, zero-drift, high-efficiency op amp with RRIO, and the MAX15007 40V, ultra-low quiescent current LDO. The EV kit also includes Windows XP®, Windows Vista® and Windows® 7-compatible software that provides a simple graphical-user interface (GUI) for exercising the features of this reference design.
