Evaluates: MAX35101 MAX35101 Evaluation Kit General Description Features and Benefits The MAX35101 evaluation kit (EV kit) provides the Easy Evaluation of the MAX35101 hardware and graphical user interface (GUI) software Two Piezoelectric Transducers and Two RTD necessary to evaluate the MAX35101 time-to-digital Connections Provided converter designed for ultrasonic heat, water, and gas EV Kit Hardware Optionally USB Powered meters. The EV kit includes a MAX35101EHJ+ installed, (USB Cable Included) as well as the required USB-to-SPI interface needed to USB HID Interface communicate with the IC. The USB-to-SPI master section Windows XP - and Windows 7-Compatible Software of the EV kit, along with the EV kit software, provides a quick method to exercise the devices functionality. RoHS Compliant The EV kit can be powered by the USB to simplify an Proven PCB Layout evaluation setup, but also comes equipped with banana Fully Assembled and Tested jacks that enable an external supply, such as a battery, to power the system. Provided BNC connectors allow for EV Kit Contents quick connection to piezoelectric transducers housed in a Circuit Board Including MAX35101EHJ+ and spool body. The provided terminal-block connectors allow USB-to-SPI Circuitry for easy connection to the two remote platinum RTDs.
