GENERAL DESCRIPTION

The ADPD2210 is a low noise current amplifier designed to

allow the use of smaller photodiodes by amplifying sensor signal

currents by a factor of 24 while adding minimal noise. This

amplification provides the system sensitivity of a large photodiode

with the benefits of a smaller photodiode. A minimum linearity

of 60 dB allows accurate extraction of very small time variant

signals on top of large dc or low frequency offsets.

The ADPD2210 is designed for applications where power

conservation is critical. The ADPD2210 uses very little power,

typically 140 μA with no input to 9±4 μA at full scale. A power-

down pin places the ADPD2210 in standby when sensing is

inactive. This mode adds critical time for battery-powered

monitoring and can reduce battery costs in disposable applications

Using the ADPD2210 to provide sensor site amplification

reduces the effect of electromagnetic interference (EMI) in low

level wired interfaces, providing improved signal-to-noise ratio

(SNR) and rejection of interferer signals from nearby equipment.

The combination of low power, high SNR, and EMI immunity

enables low power system solutions not possible with traditional

small current sensors, such as photodiodes plus transimpedance

amplifiers (TIAs).

The ADPD2210 is optimized for pulse mode applications such

as wrist worn heart rate monitoring (HRM) or finger worn

pulse oximeter oxygen saturation (SpO2), where low power

consumption and rejection of ambient light is critical. In photodi-

ode applications, the ADPD2210 holds the sensor input to

within ±± mꢀ (typical) of the reference terminal, providing

near zero-bias voltage and allowing minimal dark current and

shot noise limited performance.
