TP3069
‘‘Enhanced’’ Serial Interface
CMOS CODEC Filter COMBO
General Description
The TP3069 (A-law) is a monolithic PCM CODEC Filter uti-
lizing the A D and D A conversion architecture shown in
Figure 1 and a serial PCM interface The device is fabricat-
ed using National’s advanced double-poly CMOS process
(microCMOS)
Similar to the TP305X family this device features an addi-
tional Receive Power Amplifier to provide push-pull bal-
anced output drive capability The receive gain can be ad-
justed by means of two external resistors for an output level
of up to g6 6V across a balanced 600X load
Also included is an Analog Loopback switch and a TSX out-
put
