TP3069V

The TP3069V is one member of the TP3069 family.The TP3069 (A-law) is a monolithic PCM CODEC/Filter uti-lizing the A/D and D/A conversion architecture shown inFigure1, and a serial PCM interface. The device is fabricated using National's advanced double-poly CMOS process. The receive gain can be adjusted by means of two external resistors for an output level of up to g6.6V across a balanced 600X load.

Features of the TP3069V are:(1)Complete CODEC and filtering system including:-Transmit high-pass and low-pass filtering; -Receive low-pass filter with sin x/x correction; -Active RC noise filters; -A-law compatible COder and DECoder; -Internal precision voltage reference;-Serial I/O interface-Internal auto-zero circuitry; -Receive push-pull power amplifiers; (2)Designed for D3/D4 and CCITT applications; (3)±5V operation; (4)Low operating power-typically 70 mW; (5)Power-down standby mode-typically 3 mW; (6)Automatic power-down; (7)TTL or CMOS compatible digital interfaces; (8)Maximizes line interface card circuit density.

The absolute maximum ratings of the TP3069V can be summarized as:(1)VCCtoGNDA:7V;(2)VBBtoGNDA:-7V;(3)Voltage at any Analog Input or Output: VCCa0.3VtoVBBb0.3V;(4)LeadTemp :300; (5)Operating Temperature: -25to 125;(6)Storage Temperature Range:-65 to +150.If you want to know more information such as the electrical characteristics about the TP3069V, please download the datasheet in www.seekic.com or www.chinaicmart.com.
