LMC660 CMOS Four Movement is a amplifier
General description
lmc660 CMOS four lucky amplifiers is a single power operation. The working voltage from+5V to+15V and the rail -to -orbit output width and input include the co -mode range including ground. The limitations of performance that troubles the CMOS amplifier in the past is not the problem of this design. Enter VOS, drift and broadband noise and actual load voltage gain (2 kΩ and 600Ω) are equal to or better than the bipolar equivalent of extensive communication and acceptance. This chip is a national advanced bisodiacum CMOS process. For dual CMOS operations, see the LMC662 data table with the same function amplifier.

for the topology selected by LMC660, such as Figure 1 does not adopt traditional unit gain buffer output levels (compared to universal computing amplifiers); on the contrary, the output is obtained directly from the output of the input integror to allow orbit output to swing. Because of the tradition of the buffer, in maintaining the gain and stability of the high -transportation amplifier, it is necessary to bear whether the railway must be able to withstand the railway. These tasks are now responsible for the integrator. Due to these requirements, the integrator is an event in the phase of a complex and an embedded gain. This stage is a dual -feed (CF and CFF) compensation through a dedicated unit gain. In addition, the output part of the integral device is push -pull configuration for transporting heavy objects. When the entire amplifier path of the absorption current is the stage of obtaining first -level feedback, the source path contains four gain stages and two FED forward places.
The large signal voltage gain at the source pole is comparable to traditional bipolar computing amplifiers, even if the load is 600Ω. The gain at the time of sink is higher than that of most CMOS computing amplifiers to the additional gain stage; however, the gain (600Ω) gain will be reduced, such as the characteristics shown in the electrical diagram. 
The high input resistance of the LMC660 computing amplifier allows large feedback and source resistance values, and will not cause gain accuracy due to the load. However, the circuit will be particularly sensitive to its layout when these large value resistors are used.
Application prompts (continued)
Each amplifier has some capacitors between each input end and the differential capacitors between the exchange ground and the input end. When the amplifier is resistant, the input capacitor (and the additional capacitor sockets generated by the circuit board traces, etc.) and the feedback resistor are on the feedback path. In the following universal computing amplifier circuit, the frequency of Figure 2 is
. CS is the total capacitor input, including the amplifier input capacitance and any bandate capacitance from the IC socket (if you if the IC socket (if Use), circuit board trajectory, etc. RP is a parallel combination of RF and RIN. For the formula and all the formulas below, the formula is suitable for the configuration of reverse and non -inverse operations amplifiers. The frequency of feedback poles when the feedback resistance is less than a few KΩ, because CS is generally less than 10 PF. If the frequency of the feedback is much higher than the ideal " closed -loop bandwidth (the nominal closed -loop bandwidth of the CS)
