General Description
The TP3069 (A-law)isa monolithic PCM CODEC/Filteruti-
lizingthe A/D and D/A conversion architecture shownin
Figure1,anda serial PCM interface.The deviceis fabricat- using National’s advanced double-poly CMOS process
(microCMOS).
Similartothe TP305X family,this device featuresan addi-
tional Receive Power Amplifierto provide push-pull bal-
anced output drive capability.The receive gaincanbead-
justedby meansoftwo external resistorsforan output levelupto g6.6V acrossa balanced 600X load.
Also includedisan Analog Loopback switchandaTSXout-
put.
