AD630  
AD630 when used to modulate a 100 kHz square wave carrier  
with a 10 kHz sinusoid. The result is the double sideband sup-  
pressed carrier waveform.  
system input tied to 0 V, and a switching or carrier waveform  
applied to the comparator, a low level square wave will appear at  
the output. The differential offset adjustment pot can be used to  
null the amplitude of this square wave (Pins 3 and 4). The  
common-mode offset adjustment can be used to zero the residual  
dc output voltage (Pins 5 and 6). These functions should be  
implemented using 10k trim pots with wipers connected directly  
to Pin 8 as shown in Figures 9a and 9b.  
These balanced modulator topologies accept two inputs, a signal  
(or modulation) input applied to the amplifying channels, and a  
reference (or carrier) input applied to the comparator.

CHANNEL STATUS OUTPUT  
The channel status output, Pin 7, is an open collector output  
referenced to –VS which can be used to indicate which of the  
two input channels is active. The output will be active (pulled  
low) when Channel A is selected. This output can also be used  
to supply positive feedback around the comparator. This produces  
hysteresis which serves to increase noise immunity. Figure 7  
shows an example of how hysteresis may be implemented. Note  
that the feedback signal is applied to the inverting (–) terminal  
of the comparator to achieve positive feedback. This is because  
the open collector channel status output inverts the output sense  
of the internal comparator.

The channel status output may be interfaced with TTL inputs

APPLICATIONS: BALANCED MODULATOR  
Perhaps the most commonly used configuration of the AD630 is  
the balanced modulator. The application resistors provide precise  
symmetric gains of 1 and 2. The 1 arrangement is shown in  
Figure 9a and the 2 arrangement is shown in Figure 9b. These  
cases differ only in the connection of the 10 kΩ feedback resistor  
(Pin 14) and the compensation capacitor (Pin 12). Note the use  
of the 2.5 kΩ bias current compensation resistors in these  
examples. These resistors perform the identical function in the  
1 gain case. Figure 10 demonstrates the performance of the
