AD8510/AD8512/AD8513  
PRECISION RECTIFIERS  
Rectifying circuits are used in a multitude of applications. One  
of the most popular uses is in the design of regulated power  
supplies, where a rectifier circuit is used to convert an input  
sinusoid to a unipolar output voltage.  
However, there are some potential problems with amplifiers  
used in this manner. When the input voltage (VIN) is negative,  
the output is zero, and the magnitude of VIN is doubled at the  
inputs of the op amp. If this voltage exceeds the power supply  
voltage, it may permanently damage some amplifiers. In addition,  
the op amp must come out of saturation when VIN is negative.  
This delays the output signal because the amplifier requires  
time to enter its linear region.  
TIME (1ms/DIV)  
Although the AD8510/AD8512/AD8513 have a very fast  
overdrive recovery time, which makes them great choices for the  
rectification of transient signals, the symmetry of the positive  
and negative recovery times is also important to keep the output  
signal undistorted.  
Figure 51. Half-Wave Rectifier Signal (OUT A in Figure 50)  
Figure 50 shows the test circuit of the rectifier. The first stage of  
the circuit is a half-wave rectifier. When the sine wave applied at  
the input is positive, the output follows the input response.  
During the negative cycle of the input, the output tries to swing  
negative to follow the input, but the power supply restrains it to  
zero. In a similar fashion, the second stage is a follower during  
the positive cycle of the sine wave and an inverter during the  
negative cycle.
