The Tektronix 155-0032-00 is a differential amplifier chip made by Tektronix. It is packaged in a 16-pin DIP.
The input differential amplifier's emitters are brought out to pins 1 and 16. Off-chip components provide frequency compensation and determine the gain. The chip has an input to select normal or inverted phase and an input to vary the "position", i.e., output current offset.

Used in
- The 155-0032-00 is used in the front end of the the 335 signal path, just after a JFET high-impedance buffer. It is discussed on page 3-5 of the 335 manual.
- The 155-0032-00 is also used as the trigger amplifier in the 465. In this application, the input differential amplifier has a total tail current of about 11 mA.
- The 155-0032-00 is used as a vertical gain stage in the 7A12.
