G589

This document is a circuit schematic for a "Filtered Differential Amplifier," identified as document number G589-0-1, Revision C.

It was created by Digital Equipment Corporation (DEC) in 1969, with the design drawn by R. Clemens on 9/10/69 and checked by A. Yauga on 9/15/69. The schematic is furnished for test and maintenance purposes, and the circuits are explicitly stated to be proprietary to DEC.

The circuit features an integrated circuit (E1, MC1520G) and numerous discrete components, including inductors (L1, L2), capacitors (C1-C12), resistors (R1-R8), and diodes (D1-D8). General specifications for the components are provided: capacitors are rated at 100V, 5%; diodes are D664 (which converts to IN3606); and resistors are 1/8W, 1%, MF. The document also includes revision history and a transistor/diode conversion chart.
