Introduction

The TP3069 (A-law) is a monolithic PCM CODEC Filter utilizing the A D and D A conversion architecture and a serial PCM interface. The device is fabricated using advanced double-poly CMOS process (microCMOS). Similar to the TP305X family, this device features an additional Receive Power Amplifier to provide push-pull balanced output drive capability. The receive gain can be adjusted by means of two external resistors for an output level of up to ±6.6V across a balanced 600Ω load. Also included is an Analog Loopback switch and a TSₓ（overline） output.
