(1) Signal chain analog chip
Signal chain analog chip refers to the integrated circuit that has the ability to transmit, receive, convert, amplify and filter analog signals. The company’s signal chain analog chips have many subdivision models, which can be divided into the following three categories according to the overall function:
Category main technical level purpose
Operational amplifiers and high side wire products with various specifications and indicators are widely used. They mainly complete the amplification, filtering, selection and quasi switching of analog current detection amplifier, comparator, video filter and analog signal in the transmission process. The key technical level of some products, such as comparison and other functions. Signal amplification is the most common function under analog signal processing. It is generally realized by connecting the wired products of operational amplifier into a special amplification circuit. The bandwidth of the high side current operational amplifier is 10khz-20mhz. The detection amplifier is a special amplifier specially used to convert the high side current into static current of 0.3ua-3.5ma, with single channel and double voltage signals and amplification. Filtering has three specifications: channel and four channel. It is packaged as a general seal. It filters the signal according to the frequency characteristics and retains the installed. The design is for the purpose of general use. Parts required by different product lines. The analog switch is turned on or off by control
Category main technical level purpose
The supply voltage can support 2.7-36v; Turn off to select whether the signal is on or not, or select the required signal from multiple signal high side current detection amplifiers with signals greater than 90dB.
The comparator compares the common mode rejection ratio of the two, and has the results of low noise, low temperature drift, size between input signals and output 0 or 1 at the same time. The highest performance of common mode terminal can be supported by the following examples:
80V； The power signal conditioning and filter comparator conversion time in the communication base station can reach 3.5ns, including low wave;
The static current of the power comparator can be less than 200na; The detection of motor current and video filter in industrial frequency converter have low power consumption and excellent visual amplification;
