| Abstract: | The design of intelligent instrument circuits with high-precision bridge type sensor is briefly described. Amplifier AD625 and A/D convert chip ICL7135 applied circuits used in programmed instruments are emphasized. The power supply circuits of newer providing constant temperature and of symmetrical follow type firm voltage are also introduced, The related working principles and some problems in need of special consideration are discussed.Some practiced measures on raising precision and preventing disturbance are also proposed. |
