EL5173_EL5373 Functional Diagram
Description
Support is limited to customers who have already adopted these products.
The EL5173 and EL5373 are single and triple high bandwidth amplifiers with a fixed gain of 2. They are primarily targeted for applications such as driving twisted-pair lines in component video applications. The inputs can be in either single-ended or differential form but the outputs are always in differential form. The output common mode level for each channel is set by the associated REF pin, which has a -3dB bandwidth of over 190MHz. 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 EL5173 and EL5373 are specified for operation over the full -40°C to +85°C temperature range.
Applications
- Twisted-pair drivers
- Differential line drivers
- VGA over twisted-pairs
- ADSL/HDSL drivers
- Single-ended to differential amplification
- Transmission of analog signals in a noisy environment

- Application NotePDF 263 KB r13an0003eu0100-biasing-op-amps Dec 06, 2019AI-generated Summary: 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.
- Application NotePDF 564 KB an1993 May 22, 2018AI-generated Summary: 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.

- Application NotePDF 843 KB an535 Jun 05, 2002AI-generated Summary: 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.
