The Tektronix 155-0032-00 is an 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 for the emitter current source and the frequency compensation.

  • pin 1: emitter current source
  • pin 2: gain switching
  • pin 3: input balance
  • pin 4: bias
  • pin 5: -8V
  • pin 6: position current source
  • pin 7: ground
  • pin 8: signal out -
  • pin 9: signal out +
  • pin 10: position
  • pin 11: +8V
  • pin 12: norm / -inv
  • pin 13: +5V
  • pin 14: signal in -
  • pin 15: gain switching
  • pin 16: emitter current source

The 155-0032-00 is used in the front end of the the 335 signal path, just after a JFET high-impedance buffer. In this application, the input differential amplifier has a total tail current of about 11mA.
