This document establishes the requirements and test procedures for the procurement of an electronic summing amplifier module.
The following electrical parameters reflect the 0° to 60°C end-of-life limits from table I.
Name Amplifier, summing Family Analog Key code BED Size 1A Weight 35 grams maximum Failure rate 0.290 failures/106 hours maximum Environment Class I as specified in MIL-STD-1389 Maximum power dissipation 693 mW Supply voltages ± 15 V ± 10 percent Maximum input signal Supply voltage or ± 15 Vp Output impedance 15Ω maximum at 10 kHz Gain Programmable (unity, ½) Gain accuracy ± 0.5 dB maximum Input offset voltage 6 mV maximum Bandwidth 75 kHz minimum Output slew rate 0.3 V/µs minimum
The summing amplifier module, designated as key code BED, is a Standard Electronic Modules Program (SEMP) electronic module with 0.100 inch (2.54 mm) grid center contacts. This module contains six independent inverting amplifiers. The two summing inputs on each amplifier give a unity gain or a gain of one half. The summing node on each amplifier is brought out for gain programming.
