Precision matching coupled with a unique analog resistor trim technique is used to obtain low input offset voltages. Our devices are built using state-of-the-art proprietary technologies which provide very low offset, drift These high speed, low distortion (1 nV or less) op amps enable better signal fidelity in the most demanding conditions, allowing system designers to achieve the lowest total system noise performance in applications with high source impedances. A simple feedback network and load resistor are included for completeness. parametric-filter Operational amplifiers (op amps) parametric-filter Programmable & variable gain amplifiers (PGAs & VGAs) parametric-filter Special function amplifiers; High-speed op amps (GBW ≥ 50 MHz) parametric-filter Audio op amps; parametric-filter General-purpose op amps; parametric-filter High-speed op amps (GBW ≥ 50 MHz) parametric 2 Video Designs Using High-Speed Amplifiers 1 Introduction Video design has been the domain of discrete circuitry from the days of vacuum tubes. We offer the industry's broadest portfolio of precision op amps to fit a wide range of applications such as automotive, industrial, instrumentation and aerospace. Jacob (Jake) Baker, PhD, PE. Part # To find p4, we must find CI which is the output capacitance of the first stage of the op amp. The low noise character-istic of the OP471 is, in part, achieved by operating the input transistors at high collector currents since the voltage noise is inversely proportional to the square root of the collector current. jt pj gc pe ro qo jb nr rs sa
