GENERAL DESCRIPTION

The ADPD2211 is an optical sensor optimized for biomedical

applications. Very low power consumption and near theoretical

signal-to-noise ratio (SNR) are achieved by packaging an ultralow

capacitance deep junction silicon photodiode operated in zero

bias photoconductive mode with a low noise current amplifier.

The ADPD2211 offers a typical 400 kHz bandwidth performance,

which is well suited for use with pulsed excitation. The ADPD2211

uses very little power during operation and incorporates a

power-down pin, enabling power cycling to optimize battery

life in portable applications. The ADPD2211 provides shot

noise limited performance, making it an excellent choice for

measuring signals with the highest possible fidelity in low light

conditions. This combination of low power, very high SNR, and

electromagnetic interference (EMI) immunity enables low power

system solutions not possible with traditional photodiode (PD)

and transimpedance amplifier (TIA) systems.
