• Input coupling (AC/DC)
• Single ended / differential
• Optional passive filter

Description

The GPIA has screw-terminal inputs and outputs making it ideal for the engineering environment or research labs. The GPIA is an economical alternative to high-cost instrumentation amplifiers yet it provides all the functionality necessary for basic engineering work. Many configuration options are possible including gain, input/output filters, coupling and input resistors. The unit was designed for amplifying Hall-sensor signals but can be used for many other purposes.

A dual 12 Volt power supply is required for operation; this can be supplied separately or by the user. Power entry is through a 5-pin 180-degree DIN socket.
