ADPD103

 ▪Fully integrated AFE, ADC, LED-Driver, and Timing Core.

▪Usable in a broad range of optical measurement applications, including

▪Photoplethysmography-(PPG)

▪SpO2

▪Proximity

▪ALS

▪UV Measurement

▪Best-in class ambient light rejection capability without the need for photodiode optical filters

▪Separate data registers for each LED/PD combination

▪20 Bit burst accumulator

▪I2C interface and 1.8 V analog/digital core

▪Flexible sampling frequency ranging from 0.1 Hz to 2.6 kHz

▪FIFO Data operation

▪Onboard summation of channels to cut the number of required read-events by ¼

▪This can be used to make greater use of the FIFO.

▪Three fully tunable LED drivers

▪1 to 8 optical inputs (LFCSP)

▪1 to 2 optical inputs (WLCSP)

▪4x4 LFCSP

▪2.42 x 1.32 WLCSP

▪Released
