Description

The CA3280 and CA3280A types consist of two variable operational amplifiers that are designed to substantially reduce the initial input offset voltage and the offset voltage variation with respect to changes in programming current. This design results in reduced AGC thump, an objectionable characteristic of many AGC devices are high-performance operational amplifiers. 5 nV/ Hz Typ at 1 kHz combining excellent DC and AC characteristics. They. Unity-Gain Bandwidth: 10 MHz Typ feature very low noise, high output-drive capability,. Common-Mode Rejection Ratio: 100 dB Typ high unity-gain and maximum-output-swing bandwidths As the signal frequency varies from DC to infinity, the phase shift will vary from 0 to +180 degrees. You can also see that by varying R1, the phase shift at a given frequency will vary likewise. If the position of R1 and C1 are reversed, as in Figure 2, the transfer function becomes. Application Note 184. Digitally- Controlled ABSTRACT. The flyback power stage is a popular choice for single and multiple output dc-to-dc converters at power levels of 150 Watts or less. Without the output inductor required in buck derived topologies, such as the forward or push-pull converter, the component count and cost are reduced. This application note will re-.
