Application Notes
- Designing Photodiode Amplifier Circuits with OPA128PDF, 76 Кб, Файл опубликован: 2 окт 2000
The OPA128 ultra-low bias current operational amplifier achieves its 75fA maximum bias current without compromise. Using standard design techniques, serious performance trade-offs were required which sacrificed overall amplifier performance in order to reach femtoamp (fA = 10-15A) bias currents. - Diode-Connected FET Protects Op AmpsPDF, 49 Кб, Файл опубликован: 2 окт 2000
Providing input-overload protection for sensitive measurement circuits proves difficult when you must not degrade the circuits? performance in the process. It?s an especially tricky problem when you?re measuring a material?s dielectric properties. In such an application, an ultra-low input bias current op amp serves as a current integrator to measure a dielectric?s response to a 100V step. - Compensate Transimpedance Amplifiers Intuitively (Rev. A)PDF, 69 Кб, Версия: A, Файл опубликован: 30 мар 2005
Transimpedance amplifiers are used to convert low-level photodiode currents to usable voltage signals. All too often, the amplifiers have to be empirically compensated to operate properly. The problem can be easily understood if one looks at all the elements involved. - Tuning in AmplifiersPDF, 44 Кб, Файл опубликован: 2 окт 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 - Single-Supply Operation of Operational AmplifiersPDF, 77 Кб, Файл опубликован: 2 окт 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 AnalysisPDF, 76 Кб, Файл опубликован: 2 окт 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
