PS25201A / B

EPIC Ultra High Impedance

Electrophysiological Sensor

Data Sheet 291841 issue 3

FEATURES

Ordering Information

•

Ultra high input resistance, typically 20GΩ.

Dry-contact capacitive coupling.

PS25201B

Custom package

Input capacitance as low as 15pF.

Lower -3dB point typically 200mHz.

Upper -3dB point typically 10kHz.

-25°C to +75°C

Operates with bipolar power supply from 2.4V to

5.5V.

Plessey Semiconductors Electric Potential

Integrated Circuit (EPIC) product line targets a

range of applications.

•

Sensors supplied in a custom package with exposed

pins for surface mount assembly.

The PS25201B is an ultra high impedance

solid state ECG (electrocardiograph) sensor. It

can be used as a dry contact ECG sensor

without the need for potentially dangerous low

impedance circuits across the heart. The

resolution available is as good as or better

than conventional wet electrodes.

APPLICATIONS

•

Contact ECG signal detection for:

•

Non-critical patient monitoring

equipment.

•

Emergency response diagnostics.

Lifestyle sports and health products.

Suitable for long-term and remote

monitoring.

The device uses active feedback techniques to

both lower the effective input capacitance of the

sensing element (Cin) and boost the input

resistance (Rin). These techniques are used to

realise a sensor with a frequency response

suitable for both diagnostic and monitoring ECG

applications.
