Remove the DC Portion of Signals with the ADS7817
PDF, 55 Kb, Archivo publicado: sept 27, 2000
Unwanted portions of a signal, such as a DC pedestal, can be difficult to reject in a single supply circuit. A DC pedestal voltage most typically appears at the output of an operational amplifier with a small signal riding on top of it. This pedestal voltage is required in the analog domain to insure that the small signal that contains the pertinent information never falls below the ground potenti

Tuning in Amplifiers
PDF, 44 Kb, Archivo publicado: oct 2, 2000
Have you ever had the experience of designing an analog gain block with an amplifier that is specified to be unity gain stable only to find that it is oscillating out of control in your circuit? Or have you ever replaced a stable voltage feedback amplifier with a current feedback amplifier to find that the current feedback amplifier immediately oscillates when placed in the amplifier socket?

Single-Supply Operation of Operational Amplifiers
PDF, 77 Kb, Archivo publicado: oct 2, 2000
Operation of op amps from single supply voltages is useful when negative supply voltages are not available. Furthermore, certain applications using high voltage and high current op amps can derive important benefits from single supply operation.

Op Amp Performance Analysis
PDF, 76 Kb, Archivo publicado: oct 2, 2000
This bulletin reflects the analysis power gained through knowledge of an op amp circuit's feedback factor. Feedback dictates the performance of an op amp both in function and in quality. The major specifications of the amplifier descibe an open-loop device awaiting feedback direction of the end circuit's function. Just how well the amplifier performs the function reflects through the feedback inte
