533 Dual Sum and Invert Amplifier

ORTEC 533 Dual Sum and Invert Amplifier
  • Sums up to four linear inputs, inverting or noninverting
  • Two independent amplifiers, each with a gain of –1
  • Wide bandwidth, dc to 7 MHz
  • Wide dynamic range, 0 to ±10 V
  • Excellent temperature stability

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 non-inverting output is required, Amplifier A can be cascaded through Amplifier B to form the noninverting 4-input summing amplifier. By connecting A inputs in parallel and B inputs in parallel, the Model 533 can be used as a non-inverting amplifier with a gain of 1, 2, 3, 6, or 8.

    The wide dynamic range and wide bandwidth make the ORTEC Model 533 useful for summing and/or inverting any signals that fall within the dc to 7 MHz bandwidth, such as most NIM-standard linear or logic signals. A convenient oscilloscope monitor test point is located next to each of the six front-panel connectors.
