GENERAL DESCRIPTION
The ADPD2214 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 ADPD2214 offers a typical 75 kHz bandwidth performance, which is well suited for use with pulsed excitation.
