EM Electronics – Nanovolt Amplifiers

Miniature amplifier modules for high resolution temperature measurement and calorimetry. Resolve micro degrees with Thermocouples.

EM Electronics – Nanovolt Amplifiers

EM Electronics was formed in 1979. One of the earliest projects undertaken was the study of very low level DC amplification.

The original prototype instrument was demonstrated to the Division of Electrical Science at the National Physical Laboratory in Teddington, and shortly after this a first instrument was ordered.

A22 is a low noise amplifier module for sensitive DC measurements, data collection and systems, and is ideal for very sensitive temperature measurement using thermocouples.

The A22 has many other features desirable in a measurement amplifier. The very high loop voltage gain of 100T, or 280dB, means that high overall gain may be used, controlled precisely by feedback resistors, thus ensuring good linearity, with the accuracy defined by the feedback resistors used.
