Zusammenfassung:The utility model provides an integrated observing and controlling specialized circuit of high earth orbit satellite, wherein, a power module supplies power to a FPGA chip and supplies power to a first analog-to-digital conversion chip and a second analog-to-digital conversion chip through a voltage reference source chip. After a single-ended signal is filtered by a filter chip and is amplified by an amplifier chip, the single-ended signal is transmitted into the first analog-to-digital conversion chip. The first analog-to-digital conversion chip outputs a digital quantity signal to the FPGA chip. After a difference signal is filtered by the filter chip and is amplified by the amplifier chip, the differential signal is transmitted into the second analog-to-digital conversion chip. The second analog-to-digital conversion chip outputs a digital quantity signal to the FPGA chip. After a a differential weak signal is filtered by the filter chip and amplified by the amplifier chip, the differential weak signal is
