The circuit voltage regulator tube is connected with the capacitor and resistor components. The voltage regulator tube is connected with the AC power supply through the input capacitance in the conduction direction of it, and it limits the current in the blocking direction, so the rear capacitance recharges to stabilize the output voltage. This circuit has larger voltage pulse than the bridge type, and because the circuit is connected with the AC power supply directly, so the current consumption is small.

The 3-wire interface of the AD7714 can be equipped with a variety kinds of microcontrollers (contains the microcontroller or the microprocessor). The 3-wire serial interface can be used in the isolation system, and it can reduce the number of the optical coupler to minimum. The interface circuit of the AD7714 and 80C51 (or the 87C51, 89C51) is as shown in the figure. The 80C51 only use two interface leads (P3.0,P3.1). At this time, the non-bit DRDY of the monitoring configuration register can be used to determine the update time of the data register.

The typical application circuit of the TSS400-S1/S2 is as shown in the figure. This system uses the 3V lithium battery (E) as the power supply, the C1 and C2 are the power-supply decoupling capacitance. The crystal frequency is 32.768kHz. The external memories uses two pieces of 512 bytes 24C04 type E2PROM. The silicon pressure sensor is in the range of dotted line. You can get the measurement accuracy that is equivalent with the voltage value of 12-bit ADC by using the temperature compensation software. The analog circuit of the figure is connected with the USDD port, and it supplies power to the sensor only when the circuit need the A/D conversion, this can save the power consumption of the whole system.
