Current Input, Voltage Output, Front-End Amplifier

The LI-76A is a current-voltage converter used for detecting signals from high-impedance sensors such as photomultiplier tubes (PMTs) using locked-in amplifiers.

Power is supplied by battery (S-006P), phase-locked amplifier 5610B, LI5630, LI5640, or the dedicated DC power supply PS-70A.
