... DETAILED DESCRIPTION 3.1 Theory of Operation Figure 3-1 shows the major elements of the TC7650. There are two amplifiers (the main amplifier and the nulling amplifier), and both have offset null capability. The main amplifier is connected full-time from the input to the output. The nulling amplifier, under the control of the chopping frequency oscillator and clock circuit, alternately nulls itself and the main amplifier ...

... Clock Operation The internal oscillator is set for a 200Hz nominal chop- ping frequency on both the 8- and 14-pin DIPs. With the 14-pin DIP TC7650, the 200 Hz internal chopping fre- quency is available at the internal clock output (Pin 12 400Hz nominal signal will be present at the external 6 clock input pin (Pin 13) with INT/EXT high or open ...

... LOW during the time an overload signal is applied, neither capacitor will be charged. The leakage currents at the capacitors pins are very low. At 25°C a typical TC7650 will drift less than 10µV/sec. 3.6 Output Clamp Chopper-stabilized systems can show long recovery times from overloads ...

... Pin Compatibility On the 8-pin mini-DIP TC7650, the external null stor- age capacitors are connected to pins 1 and 8. On most other operational amplifiers these are left open or are used for offset potentiometer or compensation capaci- tor connections. For OP05 and OP07 operational amplifiers, the ...
