PIN AND FUNCTIONAL DESCRIPTIONS
(ADPCM CODEC)
AIN+, AIN–, GSX
Transmit analog inputs and transmit level adjustment pin.
The AIN– input is connected to the inverting input of the internal transmit amplifier and AIN+
input is connected to the non-inverting input. The GSX pin is connected to the output pin of the
amplifier.
See Figure 1 for level adjustment.
VFRO, SAO
Receive analog output and sounder output.
VFRO is a receive filter output pin and SAO is a sounder output pin. These outputs can directly
drive the load of over 10 kW. When the system is in the power down mode, these outputs become
high impedance.
AOUT+, AOUT–, PWI
Input and outputs for internal operation amplifier.
See Figure 1 for connection. When the system is in the power down mode, these outputs become
high impedance. The AOUT– and AOUT+ outputs can directly drive the load of over 150 W.
