PS25202

EPIC Ultra High Impedance ECG Sensor

Advance Information

Data Sheet 291498 issue 2

FEATURES

Ordering Information

•

Ultra high input resistance, typically 20GΩ.

PS25202

Custom package

Dry-contact capacitive coupling.

Input capacitance as low as 15pF.

-25°C to +75°C

Lower -3dB point typically 50mHz to meet clinical

ECG requirements.

•

Upper -3dB point typically 10kHz.

Plessey Semiconductors Electric Potential

Integrated Circuit (EPIC) product line targets a

range of applications.

Operates with bipolar power supply from 2.4V to

4.0V.

•

Sensors supplied in a custom package with exposed

pins for surface mount assembly.

The PS25202 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.
