EL8108 Functional Diagram
Description
Support is limited to customers who have already adopted these products.
The EL8108 is a dual current feedback operational amplifier designed for video distribution solutions. This device features a high drive capability of 450mA while consuming only 5mA of supply current per amplifier and operating from a single 5V to 12V supply. The EL8108 is available in the industry standard 8 Ld SOIC as well as the thermally-enhanced 16 Ld QFN package. Both are specified for operation over the full -40°C to +85°C temperature range. The EL8108 has control pins C0 and C1 for controlling the bias and enable/disable of the outputs. The EL8108 is ideal for driving multiple video loads while maintaining linearity.
Applications

- 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.

It includes important legal notices from Renesas Electronics regarding the use, liability, and intellectual property rights of their semiconductor products. The document clarifies product quality grades, intended applications, and restrictions on use in life-critical or hazardous systems. It emphasizes compliance with applicable laws and safety responsibilities when using Renesas products. Contact information for Renesas sales offices worldwide is also provided.
- Application NotePDF 8.19 MB an1548 Jan 19, 2004AI-generated Summary: The iSim Active Filter Designer sequences poles from high Q to low Q in ascending gains to reduce output clipping and noise. It allows manual or semi-automatic pole and gain entry, placing real poles last for noise and stopband advantages. The design process involves defining constraints, selecting op amps, and simulating solutions. Users can preview filter shapes or manually input poles from external tools. The tool supports multi-stage designs with selectable op amps based on supply voltage and output swing requirements.
- 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.
- Application NotePDF 245 KB an9507 Aug 22, 1998AI-generated Summary: The document outlines important legal disclaimers and usage guidelines for semiconductor products. It emphasizes user responsibility for product design and safety, disclaims liabilities for damages, and restricts unauthorized modifications or reverse engineering. Products are categorized into 'Standard' and 'High Quality' grades, each intended for specific applications. Users must comply with environmental and export laws and ensure safety measures against product failures. Contact details for Renesas Electronics sales offices worldwide are provided.
