Photometric Front Ends

Data Sheet

ADPD105/ADPD106/ADPD107

FEATURES

GENERAL DESCRIPTION

Multifunction photometric front end

The ADPD105/ADPD106/ADPD107 are highly efficient,

photometric front ends, each with an integrated 14-bit analog-

to-digital converter (ADC) and a 20-bit burst accumulator that

works with flexible light emitting diode (LED) drivers. The

accumulator is designed to stimulate an LED and measure

the corresponding optical return signal. The data output and

functional configuration occur over a 1.8 V I²C interface on the

ADPD105 or SPI on the ADPD106 and ADPD107. The control

circuitry includes flexible LED signaling and synchronous

detection.

Fully integrated AFE, ADC, LED drivers, and timing core

Enables best-in-class ambient light rejection capability

without the need for photodiode optical filters

Three 370 mA LED drivers

Flexible, multiple, short LED pulses per optical sample

20-bit burst accumulator enabling 20 bits per sample period

On-board sample to sample accumulator, enabling up to

27 bits per data read

Low power operation

SPI, I²C interface, and 1.8 V analog/digital core

Flexible sampling frequency ranging from 0.122 Hz to 3820 Hz

FIFO data operation

The analog front end (AFE) features best-in-class rejection of signal

offset and corruption due to modulated interference commonly

caused by ambient light.

APPLICATIONS

Couple the ADPD105/ADPD106/ADPD107 with a low

capacitance photodiode of <100 pF for optimal performance.

The ADPD105/ADPD106/ADPD107 can be used with any LED.

The ADPD105 is available in a 2.46 mm × 1.4 mm WLCSP and a

4 mm × 4 mm LFCSP. The SPI only versions, ADPD106 and

ADPD107, are available in a 2.46 mm × 1.4 mm WLCSP.
