155-0057-00
The Tektronix M053B (P/N 155-0057-00) is a amplifier monolithic integrated circuit that contains two operational amplifiers and two opamps connected as current sources in a Minipac package. It was designed by Dave Allen.
It is a variation of the 155-0035-00/155-0116-00 quad op-amps.
An Article in Electronics, February 20, 1975, says
Fortunately, a group within Tektronix' Information Displays division was developing a quad op amp for a graphic terminal. This IC more than met the 211's requirements, and since it was close to completion, Allen chose to run with it instead of the other vertical amplifier circuits. To make this circuit operate in the model 211, the metallization pattern on the die had to be altered. Parts of two of the four op amps were used as constant-current sources for the FET inputs on the other two op amps. The rest of the circuitry was not needed. The result was a simple circuit that performed much like the earliest vertical amplifier design but could be used in a wider range of applications.
