ANALOG DEVICES MAX86180 Evaluation System
General Description
The MAX86180 evaluation system (EV system) allows for the quick evaluation of the MAX86180 optical AFE for applications at various sites on the body, particularly the wrist. The EV system supports both I2C and SPI-compatible interfaces. The EV system has two optical readout channels that operate simultaneously. The EV system allows flexible configurations to optimize measurement signal quality at minimal power consumption. The EV system supports file logging and flash logging, allowing the user to disconnect from the computer for more convenient data-capturing sessions, such as overnight or outdoor running.
The EV system consists of two boards. MAXSENSORBLE_ EVKIT_B is the main data acquisition board while MAX86180_OSB_EVKIT_B is the sensor daughter board for the MAX86180. To enable PPG measurement capabilities, the sensor board contains seven LEDs (one OSRAM SFH7016, red, green, and IR 3-in-1 LED package, one OSRAM SFH4053 IR LED, one QT-BRIGHTER QBLP601-IR4 IR LED, one Würth Elektronik INC. W150060BS75000 Blue LED and one QT-BRIGHTERQBLP595-AG1 green LED) four discrete photodiodes (VISHAY VEMD8080), and an accelerometer.
The EV system is powered through a LiPo battery attached to it and can be charged using a Type-C port. The EV Sys communicates with MAX86180GUI (should be installed in the user’s system) using Bluetooth® built into Windows® (Win BLE). The EV sys contains the latest firmware but comes with the programming circuit board MAXDAP-TYPE-C in case a firmware upgrade is needed. Ordering Information appears at the end of the datasheet. Visit Web Support to complete the nondisclosure agreement (NDA) required to receive additional product information.
