The difference is as follows: \u003C/span>\u003C/p>\r\n\u003Cp>\u003Cspan style=\"font-family: trebuchet-ms;\">1. The flipping speed of the comparator is fast.It is on the order of ns, and the op amp flip speed is typically on the order of us (except for special high-speed op amps).There is no phase compensation circuit inside, which is the main reason why the comparator is much faster than the op amp.\u003C/span>\u003Cspan style=\"font-family: trebuchet-ms;\">3. The output stage of the op amp generally uses a push-pull circuit and a bipolar output.Most comparator output stages are open-collector structures, so pull-up Resistorss, unipolar outputs, and easy connection to digital circuits are required.Used as an amplifier. Because the comparator is optimized for speed, this optimization reduces the range of closed-loop stability. The op amp is optimized for the closed-loop stability range, so the speed is reduced. So the comparators of the same price grade andThe amplifier is best responsible for each other. Just as the amplifier can be used as a comparator, the ratio cannot be excluded.Check to ensure stability in all working conditions of the product! At this time you have to carefully calculate the cost/risk.\u003C/span>\u003C/p>\r\n\u003Cp>\u003Cspan style=\"font-family: trebuchet-ms;\">2. The amplifier and comparator are exactly the same. In a nutshell, the comparator is the open-loop application of the op amp.However, the comparator design is for voltage threshold comparison, and the required comparison threshold is accurate.General situation: When using an op amp as a comparator, most of them do not reach the full-scale output, or the edge time after comparison is too long. Therefore, it is better to use the op amp as a comparator in the design.\u003C/span>\u003C/td>\r\n\u003C/tr>\r\n\u003C/tbody>\r\n\u003C/table>\r\n\u003Cp>\u003Cspan style=\"font-size: inherit;\">\u003Cbr />\r\n\u003C/span>\u003C/p>","3a9148f7188da4f2d8a",378,"how-to-distinguish-between-amplifiers-and-comparators",{"summary":40,"images":7,"institutionId":7,"horizontalCover":7,"siteId_dictText":8,"updateTime":33,"title":41,"verticalCover":7,"content":42,"tags":43,"cover":7,"createBy":7,"createTime":12,"updateBy":7,"cateId":13,"isTop":14,"siteId":15,"id":44,"cateId_dictText":17,"views":45,"isPage":14,"slug":46,"status":20,"uid":44,"coverImageUrl":21,"createDate":12,"cate":13,"cateName":17,"keywords":43,"nickname":22},"What are the basic components and functions of the five statement structures?

The operation of the amplifier is always in a timely state, but the sound quality is worse than the former.When purchasing a power amplifier, first pay attention to some of its technical indicators: 1, input impedance: usually indicates the size of the power amplifier’s anti-interference ability, generally 5000 ~ 15000 Ω, the greater the value represents the stronger anti-interference ability; 2Distortion: refers to the degree of distortion of the output signal compared to the input signal.In addition, when purchasing a power amplifier, you must also specify your willingness to purchase. If you want to install a subwoofer, it is best to buy a 5-channel amplifier. Usually 2-channel and 4-channel speakers can only push the front and rear speakers.The subwoofer can only be equipped with another amplifier, and the 5-channel amplifier can solve this problem.\u003C/span>\u003C/td>\r\n\u003C/tr>\r\n\u003C/tbody>\r\n\u003C/table>\r\n\u003Cp>\u003Cspan style=\"font-size: inherit;\">\u003Cbr />\r\n\u003C/span>\u003C/p>\r\n\u003C/div>\r\n\t\t\t\t\t\t\u003Cdiv class=\"clear\">\u003C/div>\r\n\t\t\t\t\t\t\r\n\t\t\t\t\t\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t\t\u003C!-- clear for photos floats -->\r\n\t\t\t\t\t\t\u003Cdiv class=\"clear\">","power","7bfb0dab29cc87dc660",175,"how-to-choose-a-car-power-amplifier",1892,1776841274484]
