Amplifiers

These are our standard, general-purpose low-noise amplifiers with a high-impedance JFET input. The amplifiers are AC-coupled, and require only a single rail supply. Thanks to the large geometry of the input FET the amplifiers excels by its extraordinarily low noise density.

For the suppression of common-mode noise sources the FLN-series comes in balanced variants. The amplifier requires a dual rail supply, and is AC-coupled.

This is the ultra low-noise member of the FLN-series. The input contains multiple JFETs in parallel, each having a very large geometry. The result is a noise density so low that it challenges preamplifiers with transformer coupled input. The amplifier is AC-coupled and requires a single rail supply.

This buffer efficiently isolates a load from the source, and easily drives complex loads. The buffer is DC-coupled, and features a low offset voltage, a low bias current and a gain very close to one, to minimize uncertainly contributions.

This buffer allows you to tap an RF signal so that it can be scrutinized without interference. The buffer may be inserted in the signal path for minimum loading. The buffer is AC-coupled and needs only a single rail supply.

This amplifier provides a flat, stable gain of +20 dB over a wide frequency range. Being DC-coupled the amplifier requires a dual rail supply.

The amplifier targets ultrasonics, and applications with piezo control.
