Application Boards for EPIC sensor PS25202

Features

Description

The PS25012A2 and PS25012B2 are single and

boards

demonstration of the Plessey PS25202 electric

potential sensor.

•

Ultra high input resistance, typically 5x10¹⁰Ω.

dual

channel

application

for

the

Frequency response (-3dB) 50mHz to 4.0kHz.

Wide operating voltage from 4.0 to 8.0V.

Operating temperature range 0 to 50ºC.

200pF load drive capability.

The PS25202 electric potential sensors on these

boards allow the measurement of a wide range of

electric potential sources from electrophysiological

signals through to spatial electric field. The sensors

incorporate a DC block feature that allows the DC

component of an applied signal to be rejected while

maintaining good low frequency response. The

electrode surface of the detector is passivated with a

thin dielectric that allows the direct application to a

test surface. In the case of contact with skin there is

no need for electrically conductive gel.

Ground referenced output.

DC signal rejection.

Dual sensor board allows differential operation.

Applications

•

Electrophysiological signal detection.

• ECG/EOG/EMG/EEG

Electric field and potential sensing.

• Movement sensing

The PS25202 sensor demonstrated on these boards

is an integrated assembly designed for surface

mount assembly on a motherboard.

The application boards provide the regulated +2.5V

and generated -2.5V supplies that are used to

operate the sensor. This allows the boards to

demonstrate the sensors from a wide, single sided,

power supply voltage while the output of the sensor

can cover the range 2.1V. The boards are

connected by a high reliability five pin connector.

Two single channel PS25012A2 boards or a dual

channel PS25012B2 board may be used to generate

a differential signal. A typical example is shown in

Figure 3 below:
