The BUF 0.12 is a CMOS-based precision buffer amplifier, operating in room temperature down to deep cryogenic environments (T = 4.2 K, liquid helium).
BUF 0.12 covers a frequency range from 0 Hz to 10 MHz in terms of max. 1% voltage deviation.
It features a very high input impedance and has an input voltage noise in the order of 5 nV/√Hz.
The device is based on highly-doped silicon CMOS technology which allows for operation over a very wide temperature range from room temperature to liquid helium temperature, provided the device is located in a vacuum cryostat.
- precision voltage buffer DC 0 Hz to 10 MHz
