TP3069
Description
The TP3069 (A-law) is a monolithic PCM CODEC Filter utilizing the A D and D A conversion architecture shown in Figure 1 and a serial PCM interface The device is fabricated using National’s advanced double-poly CMOS process (micro CMOS) 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 g 6 6V across a balanced 600X load Also included is an Analog Loopback switch and a TSX output
