ADPD142RG-BCEZ-RL is a dedicated analog front-end for a broad range of photoplethysmographic (PPG) sensors, specifically optimized for tracking finger pulse oximetry signals. It provides a flexible and programmable interface between a PPG sensor and microcontroller (MCU). The device includes an IR/RED emission driver, an amplifier, a DC subtractor, and an analog output stage. It is designed to be tsignal robust and low power in the face of changing physiological conditions, environment and long-term product lifecycle.

Application Field

The ADPD142RG-BCEZ-RL is a sensor interface that is particularly suitable for medical, fitness, and health monitoring applications. It has a low power consumption, high performance and provides an analog output that is highly linear with respect to the PPG signals. It is capable of operating in both continuous and sleep mode and is optimized for tracking finger pulse oximetry signals.

Working Principle

The ADPD142RG-BCEZ-RL consists of four main blocks: an emission driver, a PPG signal amplifier, a DC subtractor, and an analog output stage. The emission driver is used to turn on the infrared/red light source of the PPG sensor. The PPG signal amplifier amplifies the signal from the PPG sensor and adds a low-frequency noise reduction for fewer artifacts in the signal. The signal is then sent to the DC subtractor, which subtracts the DC signal and produces a higher resolution signal with increased dynamic range. The signal is then passed to the analog output stage, which consists of a low-pass filter to remove the high-frequency noise and then sent to the MCU/SoC.

The ADPD142RG-BCEZ-RL is designed to provide a robust sensor interface in the face of changing physiological conditions, environment and long-term product lifecycle. It has a low-power consumption and a high level of signal output performance. In addition, it supports multiple programming and power conservation modes for smart energy management, allowing the device to be used for low-power sensing applications.

The ADPD142RG-BCEZ-RL is a great sensor interface for applications in the medical, fitness and health monitoring industry. It provides a robust and low-power solution for measuring PPG signals, and its analog output is highly linear with respect to the PPG signals. It is designed to be tsignal robust and low power in the face of changing physiological conditions, environment and long-term product lifecycle.
