Model 533 Dual Sum and Invert Amplifier

The ORTEC Model 533 Dual Sum and Invert Amplifier is a single-width NIM that incorporates two wideband unity-gain amplifiers. Amplifier A has four summing inputs and Amplifier B has two summing inputs. Both amplifiers invert the signals. If a noninverting output is required, Amplifier A can be cascaded through Amplifier B to form the noninverting 4-input summing amplifier.
