155-0032-00
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. It is discussed on page 3-5 of the 335 manual. In this application, the input differential amplifier has a total tail current of about 11mA.
