Precision op amp clamp circuit

.

AD I imagine the switch is a regular cmos mux. Contents move to sidebar hide. The circuit also does not solve the saturation problem.

Explore the intriguing world of voltage clamp circuits, their principle, components, and broad applications in electronics and neuroscience. The concept of voltage clamping is integral to the field of electronics and neuroscience. This article aims to provide a detailed and intuitive understanding of voltage clamp circuits, their workings, and their applications. Before we delve into the specifics, it is essential to grasp the fundamental concept. This is achieved by an external electronic circuit known as a voltage-clamp circuit. The core idea is to prevent the voltage across the device from going beyond a predetermined level, despite changes in the input voltage. The functionality of a voltage clamp circuit depends on its composition. Generally, it involves a feedback mechanism that enables the circuit to maintain the desired voltage level.

Precision op amp clamp circuit

Input-overvoltage-protected, low-power, low-noise four-channel op amp with super-beta inputs. Zero-drift technology. Post-assembly polysilicon fuse blowing trim technique enables longevity and long term stability without compromising miniaturization. Bipolar - super-beta technology. Reduces the input bias current and current drift which minimizes current noise density. The well-matched transistors help achieve very low offset voltages. The dielectric isolation helps reduce parasitic capacitance and leakage therefore providing better voltage coefficient when compared to the junction capacitance of a non-dielectrically isolated JFET.

The function relies on the opamp going open loop. SMF 2. You're right, it doesn't work. The following pages on the English Wikipedia use this file pages on other projects are not listed :. The circuit you showed, as far as I understand, does a different thing. You cannot overwrite this file. Low Noise post-regulator. If so, how can it be modified to avoid saturation? Welcome, Guest. Download as PDF Printable version. It's up to you how to power up OP amp. Low Noise LDO lm

An alternating current always changes its direction over time, but the direct current flows continuously in one direction.

This image or media file may be available on the Wikimedia Commons as File:Precision op-amp clamp. Contents move to sidebar hide. Is it bad in this clamp circuit? EEVblog on Youtube. The comparator has no hysterisis. Minorax talk contribs. The 1st BJT version is not really working because of the CE saturation voltage and effect of the base current driving a high impedance target. The version with comparator and switch should work OK when the input is low impedance. There is nothing that wrong with the initial circuit. O'k, first circuits just shows line of thoughts, R3 should be replaced by zenner. I wonder if there is any way to provide this feedback to keep output within the linear region and not affect the input signal at the same time, or achieving this in some other way.
