Maxim Sensor Reference Designs
Maxim's MAXREFDES14, MAXREFDES15, MAXREFDES16, MAXREFDES23DB, MAXREFDES27, MAXREFDES38, MAXREFDES70 are each sensor related reference designs. The MAXREFDES14 Sonoma is an energy measurement subsystem reference design that provides galvanic isolation from the system with a single pulse transformer while using resistors as the sensing elements. The MAXREFDES15 Monterey is an ultra-low power, high accuracy 4-20mA 2-wire current loop sensor evaluation board. The MAXREFDES16 Novato is a 16-bit, high-accuracy, loop-powered temperature transducer that transmits temperature information from a remote object to the central control unit over a 4-20mA current loop and using the highway addressable remote transducer (HART) communication protocol. The MAXREFDES23DB Santa Cruz is the world's smallest IO-Link light sensor with six integrated sensors ambient light (clear), red, green, blue, infrared, and temperature all on a tiny printed circuit board (PCB) that is 6.5mm x 25mm. The MAXREFDES27 is a tiny IO-Link proximity sensor with an IR receiver, matching IR LED
driver, IO-Link transceiver, and energy-efficient step-down converter
all on an 8.2mm x 31.5mm printed circuit (PC) board. The MAXREFDES38 provides the low-power, high-speed, high-accuracy analog front-end designed for the ECT/EPT or current fault sensor application. The MAXREFDES70 uses ultrasonic Time-of-Flight (ToF) which sends and receives ultrasonic
waves between piezoelectric transducers in both the upstream and
downstream directions in the pipe.
