- Operational Amplifier Macromodels: A ComparisonPDF, 59 Kb, Archivo publicado: sept 27, 2000
All major competitors in the operational amplifier markets are providing their customers Spice-based macromodels. These models give the designer a tool to do initial characterization and a limited amount of system troubleshooting. In the interest of faster simulation times and lower CPU memory requirements, macro topologies have been developed to simulate a majority of the op amp's performance cha - Tuning in AmplifiersPDF, 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? Oscil - Level Shifting Signals with Differential AmplifiersPDF, 23 Kb, Archivo publicado: sept 27, 2000
The INA105 is a unity gain differential amplifier consisting of a premium grade operational amplifier and an on-chip precision resistor network. The self-contained INA105 makes it ideal for many applications. One such application is precision level shifting. - Single-Supply Operation of Operational AmplifiersPDF, 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. - An Error Analysis of the ISO102 in a Small Signal Measuring ApplicationPDF, 29 Kb, Archivo publicado: sept 27, 2000
High accuracy measurements of low-level signals in the presence of high isolation mode voltages can be difficult due to the errors of the isolation amplifiers themselves. - Op Amp Performance AnalysisPDF, 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
