applications of precision rectifier

When the input voltage is negative, there is a negative voltage on the diode, so it works like an open circuit, no current flows through the load, and the output voltage is zero. Precision rectifiers are used in the design of instrumentation Precision rectifier. The precision rectifier using LT1078 circuit is shown above. But diodes being cheaper than a center tap transformer, a bridge rectifier are much preferred in a DC power supply. Moreover, in an integrated circuit (IC), the modularity of sub-circuit is preferred, especially for the ease of fabrication.
