Parameter Interpretation and selection of common op ops, Parameters There are many parameters for Integrated Op-ops. The main parameters are DC and AC indicators, and all chips have limit parameters. This article takes NE5532 as an example to briefly explain each indicator. The following content is not only captured from the NE5532 Data Manual, but also from the network.Limit Parameter It is mainly used to

Q: If the input signal is systematically referenced, must the capacitive coupling be added? I am actually testing, either positive, inverting input, operation is not working.A: The capacitive coupling is isolated from the DC component, and the non-work may be caused by no static working point. AC Signal amplification Circuit or audio amplification circuit, you can also use a power bias circuit, the static DC output voltage is reduced to half the supply voltage, based on a single supply operation

Target detection (object detection), which requires the model not only to determine what kind of target is included in an input image, but also to frame the target location (bounding box). In order to achieve these requirements, the traditional method is to use the sliding Windows (Sliding window) way, with different scales (scale), proportional (aspect Ratio) window on the image slide, poor to enumerate all possible locations of sub-image blocks. These sub-image blocks are then entered into the

Linear regulator based on op ampLinear regulator based on op ampWhy DIY?There are two reasons, the first is the market on the three-terminal regulator does not meet the requirements, either performance is not good, or not enough power.Second, the market also has a single show, excellent performance of the regulator, but they are expensive,For example, Ling Linear Technology's lt1581,13 dollars/piece, buy a

After more than 3 years of groping, experienced a bear market bull's experience, and finally completed the long-held OP trend system practice, next, I will be in the post-disaster, every day to share the OP trend system signal, can be very responsible, after 10 years of historical data testing, plus 3 years of real plate, More determined my confidence in this OP

, especially for the experienced excellent operation and maintenance of talent demand, And the older the more valuable; At present, domestic graduates are basically the choice of training (limited to large companies), high cost, and no experience to join the company will lead to slow technology updates, the impact of the company's technological development; Of course, graduates are also good: a white paper, plasticity, more identification and easy to

scenarios where phase consistency is emphasized, phase effects need to be considered.5, grounding, the eternal topic.Reasons for the self-excitation of op-amp shocks:1, the loop gain is greater than 1 2, the signal before and after the phase difference of 360 degrees, that is to be able to form positive feedback.Reference to "the principle of self-control" and "Circuit design based on OP amps and analog in

Before using Multisim to do op amp circuit simulation found that op amp output is more than the phenomenon of power rails, and sometimes want to take the OP put when the comparator do open-loop simulation, but in the Multisim simulation is actually linear amplification, and output over the supply voltage, very depressed, so after simulation is used cadence The or

1 Topic Description: There is an array: 2,1,4,3. For an array, there is an operation op (idx): Moves the number corresponding to the index to the first. Like what: OP (3): 2 1-> 3 2 1 4 OP (1): 3 2-> 2 3 1 4OP (2): 2 3 1 4-> 1 2 3 4 Q for a given array, each element of the array is an arbitrary integer, possibly with duplicate values, and how many

A few days ago, I heard from my friends that I was talking about PIM on mobile. This is a cutting-edge technology. I suddenly remembered that I used to see an article on Sun's website about Pim, so I will give a rough introduction to it today. Pim refers to personal Infomation Management (personal information management), which is mainly used for important user information, such as communication records, reminders, and schedules. Pim op defines a seri

During the weekend 《Attacking giantI liked its super-burning op "gongya of Red Lotus" very much and found its Chinese lyrics, very good translation (most popular Chinese translation of the animation op is quite good ): The name of hua Xie's fallen victim is hard to identify so far The Fallen birds of the earth looked forward to the wild Pray for any changes in the world To change the present, we can

First, the main parameters of the integrated op amp 1.1 Open-loop differential mode voltage amplification factor AUOAUO=20LG (uo/ui) DBAUO is an important factor to determine the stability and precision of the op amp Circuit, hoping that the bigger the AUO the better. 1.2 Maximum output voltage Uoppat a certain supply voltage, the integrated op-amp output v

Pm--product Manager This is what the product manager means. I always thought it was the project manager's abbreviation. Too pit Dad, I also wrote a cock wire article, it seems to be laughable. Rd--research and develop RD is research and development (R D). Apes like PHP programs, java program Apes, both crazy and Android belong to this category. FE--Front end development Fe is the front-end development. It's a little interesting! ue--User Experience

OP amp Pee(a) we must first understand the virtual short, virtual break. This is what constitutes the op amp always①Virtual Break : 2, 32 points between the open circuit. No current (how much bit)Virtual Short : 2, 32 point voltage, no pressure difference (somewhat)② Why is there a virtual break in the op amp, short?We take the CA3130 that we use often.This is CA
