EL5175_EL5375 Functional Diagram
Description
The EL5175 and EL5375 are single and triple high bandwidth amplifiers designed to extract the difference signal from noisy environments. They are primarily targeted for applications such as receiving signals from twisted-pair lines or any application where common mode noise injection is likely to occur. The EL5175 and EL5375 are stable for a gain of one and requires two external resistors to set the voltage gain for each channel. The output common mode level is set by the reference pin (VREF), which has a -3dB bandwidth of over 450MHz. Generally, this pin is grounded but it can be tied to any voltage reference. The output can deliver a maximum of ±60mA and is short circuit protected to withstand a temporary overload condition. The EL5175 is available in the 8 Ld SOIC and 8 Ld MSOP packages and the EL5375 in the 24 Ld QSOP package. All are specified for operation over the full -40°C to +85°C temperature range.
Applications
- Twisted-pair receivers
- Differential line receivers
- VGA over twisted-pair
- Differential to single-ended amplification
- Reception 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.

It covers input offset adjustment, AC recovery with bypass capacitors to preserve high-frequency signals, and input limiting with Schottky diodes to prevent saturation. Reflection control and AC impedance termination reduce signal distortion. ESD protection is implemented with Schottky diodes to safeguard against static discharge. The output network includes an auto gain adjust circuit using transistors to maintain signal integrity and prevent saturation, optimizing data transmission over long cables.

- Application NotePDF 929 KB an1307 Jan 19, 2004AI-generated Summary: The document addresses common video transmission issues over CAT-5 cables, including ghosting caused by improper termination, color mismatch due to gain or offset differences, common-mode noise affecting synchronization, power supply noise causing picture disturbances, and channel timing mismatches leading to color blurring. It explains termination schemes for driver and receiver sides, and presents equalization techniques to compensate for signal attenuation and distortion inherent in CAT-5 cables. Solutions include hardware adjustments and integrated circuits for delay and gain correction.
- 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.
