CXA1915AN
Notes on Operation
1. Connection to RF amplifiers
In the CXA1915AN, the RF signals (I, J) are of the voltage-output type. Therefore, the RF amplifier should
have an I-V amplifier at the input block because the servo signals (A to F) are of current-output type.
2. Power supply
The CXA1915AN can be used either with a dual positive/negative power supply or with a single power
supply. However, this IC is not provided with a center voltage generating circuit, and so when used with a
single power supply the center voltage must be supplied by an RF amplifier or some other device.
Power supply connections for each case are as follows.
Note)
Pins 3 and 9 are shorted in the IC.
For both a dual positive/negative power supply and a single power supply, the voltage difference between
the Vcc and GND pins should be within the range of 2.5 V and 5.5 V.
