描述
Support is limited to customers who have already adopted these products.
The HA-5020 is a wide bandwidth, high slew rate amplifier optimized for video applications and gains between 1 and 10. Manufactured on Intersil’s Reduced Feature Complementary Bipolar DI process, this amplifier uses current mode feedback to maintain higher bandwidth at a given gain than conventional voltage feedback amplifiers. Since it is a closed loop device, the HA-5020 offers better gain accuracy and lower distortion than open loop buffers. The HA-5020 features low differential gain and phase and will drive two double terminated 75Ω coax cables to video levels with low distortion. Adding a gain flatness performance of 0.1dB makes this amplifier ideal for demanding video applications. The bandwidth and slew rate of the HA-5020 are relatively independent of closed loop gain. The 100MHz unity gain bandwidth only decreases to 60MHz at a gain of 10. The HA-5020 used in place of a conventional op amp will yield a significant improvement in the speed power product. To further reduce power, HA-5020 has a disable function which significantly reduces supply current, while forcing the output to a true high impedance state. This allows the outputs of multiple amplifiers to be wire-OR’d into multiplexer configurations. The device also includes output short circuit protection and output offset voltage adjustment. For multi channel versions of the HA-5020 see the HA5022 dual with disable, HA5023 dual, HA5013 triple and HA5024 quad with disable op amp data sheets.

- 应用说明英语PDF 263 KB r13an0003eu0100-biasing-op-amps 2019年12月06日AI 生成的摘要: Proper biasing of operational amplifiers is essential to avoid malfunction in AC-coupled circuits. A missing DC bias path causes long stabilization times and potential failures. Adding input resistors to ground provides a DC path for bias currents, minimizing offset errors. For single-supply AC-coupled amplifiers, biasing uses a reference voltage, ideally from a high-PSRR voltage reference or buffered voltage divider, to maintain signal symmetry and reduce noise. Understanding frequency responses of input and feedback components is crucial for setting bandwidth and gain characteristics.
- 应用说明英语PDF 564 KB an1993 2018年5月22日AI 生成的摘要: Voltage feedback (VFB) amplifiers use a differential input pair, a high-impedance stage, and an output buffer to convert input voltage differences into output voltage. The VFB amplifier's gain decreases at a dominant pole frequency due to compensation capacitors. Current feedback (CFB) amplifiers include a class AB input amplifier, current mirror, high-impedance stage, and output buffer. CFB amplifiers provide faster switching and higher slew rates by drawing charge/discharge currents directly from supply rails, unlike VFB amplifiers which are limited by biasing current sources.

- 应用说明英语PDF 843 KB an535 2002年6月05日AI 生成的摘要: A Data Acquisition System (DAS) requires careful design of signal conditioning, transducer selection, and signal transmission to ensure high accuracy. Signal conditioning includes multiplexing, amplification, filtering, and calibration, ideally performed near the transducer. Transducers convert physical variables to electrical signals, often voltage, with low source resistance preferred. Signal paths can be single-ended or differential; differential paths better reject common mode noise, especially for low-level signals. Shielded twisted pairs and balanced lines reduce interference. Filters, typically Butterworth low-pass, prevent aliasing and maintain signal integrity.

It highlights layout considerations to minimize stray capacitance and noise, advises on component selection, and discusses noise characteristics and accuracy differences between CFAs and VFAs. CFAs offer better high-frequency performance and cost advantages but require careful design adjustments.
