Application Boards for EPIC sensor PS25402

Features

Description

The PS25014A2 and PS25014B2 are single and

dual channel application boards for the

demonstration of the Plessey PS25402 electric

potential sensor.

•

Ultra high effective input impedance, typically 20GΩ.

Wide operating voltage from 4.0 to 8.0V.

Operating temperature range 0 to 50^oC.

200pF load drive capability.

Ground referenced output.

The PS25402 electric potential sensors on these

boards allow the measurement of a wide range of

electric potential sources. Two sensors may be used

differentially to determine 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

an inert dielectric that provides environmental

protection. These sensors are not intended for direct

coupling to the surface of the skin. In the case of

electrophysiological sensing the following sensors

should be used:

DC signal rejection.

Dual sensor board allows differential operation.

Movement sensing due to electric field

disturbance

The application boards provide a 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.
