The M377 is a Tek-made amplifier integrated circuit designed by John Addis. It is used in the 11A32, 11A33, 11A34, and 11A52.
About the M377, John Addis says:
The M377 was a single channel plugin on a chip with 0V common mode input and output voltages, excellent variable gain control, two four pole bandwidth limits, three outputs which could be separately inverted and turned on or off.
It was the first wideband analog IC with level shift on chip (allowing 0V common mode input and output and without PNP transistors), first wideband amplifier with any on-chip bandwidth limit selection, first to have more than two fixed gain settings (it has six), and first to require only one transient response adjustment (no thermals), and the first to have a highly linear relationship between a control voltage and gain. It also had excellent overdrive recovery.
