RTKA-BDGSTKEV1Z

RTKA-BDGSTKEV1Z is a DAQ on a stick, strain gauge with programmable chopper stabilized in amp. The DAQ on a stick strain gauge with programmable in amp is one of a series of reference designs highlighting Renesas' precision products with different microcontrollers. This reference design is a self-contained demo showing a complete signal chain solution using Renesas parts and a Renesas microcontroller. This compact design draws power through the USB port and uses a graphical user interface (GUI) to display the real-time voltage readings from a bridge strain gauge or a user supplied sensor. The design uses Renesas's ISL28634 programmable instrumentation amplifier (in amp), ISL23328 digital potentiometer, ISL28233 operational amplifiers, ISL43840 dual 4-channel multiplexer (Mux) configured as a differential Mux, ISL21010 4.096V voltage reference, ISL21010 3.3V voltage reference, the ISL26104 24-bit Delta-Sigma converter and the R5F10JBC (RL78/G1C) microcontroller.
