The LA-22 Low Noise Lab Amplifier is intended to make it easy to do low-level measurements
using ordinary lab equipment such as oscilloscopes, spectrum analyzers, and data acquisition
bricks, which usually have noise levels in the tens of nanovolts per root hertz.

The LA-22 has 1-nV/ √Hz voltage noise, wide bandwidth, FET input, 100× gain, and
good manners: in the time domain, 20-ns edges with low overshoot, and in the frequency
domain, 500 Hz–20 MHz bandwidth with a smooth rolloff and no high-frequency peaking.
