Sensor Reference Designs

Analog Devices Inc. MAXREFDES15, MAXREFDES16, MAXREFDES23DB, MAXREFDES27, MAXREFDES38, and MAXREFDES70 are each sensor-related reference designs. 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.
