ISL28276_ISL28476 Functional Diagram
Description
Support is limited to customers who have already adopted these products.
The ISL28176, ISL28276 and ISL28476 are single, dual and quad channel micropower operational amplifiers optimized for single supply operation over the 2. 4V to 5V range. They can be operated from one lithium cell or two Ni-Cd batteries. These devices feature an Input Range Enhancement Circuit (IREC) which enables them to maintain CMRR performance for input voltages 10% above the positive supply rail and down to the negative supply. The output operation is rail-to-rail. The ISL28276 and ISL28476 draw minimal supply current while meeting excellent DC-accuracy, AC-performance, noise and output drive specifications. The ISL28276 (QSOP package only) contains a power-down enable pin that reduces the power supply current to typically 4µA in the disabled state.
Applications
- Battery- or solar-powered systems
- 4mA to 25mA current loops
- Handheld consumer products

- 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 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.
