描述
The EL5171 and EL5371 are single and triple bandwidth amplifiers with an output in differential form. They are primarily targeted for applications such as driving twisted-pair lines in component video applications. The input signal is single-ended and the outputs are always differential. On the EL5171 and EL5371, two feedback inputs provide the user with the ability to set the gain of each device (stable at minimum gain of one). For a fixed gain of two, please see EL5170 and EL5370. The output common mode level for each channel is set by the associated VREF pin, which have a -3dB bandwidth of over 50MHz. generally, these pins are grounded but can be tied to any voltage reference. All outputs are short circuit protected to withstand temporary overload condition. The EL5171 and EL5371 are specified for operation over the full -40°C to +85°C temperature range.
应用
- Twisted-pair driver
- Differential line driver
- VGA over twisted-pair
- ADSL/HDSL driver
- Single-ended to differential amplification

- 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.
