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. There are some potential
problems for amplifiers used in this manner.

TIME (1ms/DIV)
V
0
When the input voltage (V
IN
) is negative, the output is zero. The
magnitude of V
IN
is doubled at the inputs of the op amp. This
voltage can exceed the power supply voltage, which would dam-
age some amplifiers permanently. The op amp must come out of
saturation when V
IN
is negative. This delays the output signal
because the amplifier requires time to enter its linear region.
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 in keeping the
output signal undistorted.

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.
