Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] Such as figure 1 Shown: a small signal isolation transmission circuit, including a first reference circuit, a first reference circuit, an addition circuit, an isolation circuit, a proportional adjustment circuit, a subtraction circuit, and a limiter clamp circuit.
[0026] The first reference circuit includes a resistor R1, a resistor R2, a resistor R3, an operational amplifier U1, and a Zener diode Z1. The fifth pin of U1 is connected to the input terminal VCC through R3 and R1, and the sixth pin of U1 is connected to the seventh pin of U1. The first pin of Z1 is connected between R1 and R3, the second pin of Z1 is connected between R2 and R3, the third pin of Z1 and one end of R2 are grounded. Among them, Zener diode Z1 can be used as a high-precision reference voltage source, which can generate a high-precision voltage refe...
