TP3069
‘‘Enhanced’’ Serial Interface
CMOS CODEC/Filter COMBO
é
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
g
6.6V across a balanced 600
X
load.
Also included is an Analog Loopback switch and a TS
X
out-
put.
Note:

COMBO Circuits.’’
