Now over 1,400 items in our Store! m-law) and TP3067 (A-law) are monolithic PCM CODEC/Filters utilizing the A/D and D/A conversion architecture shown in Figure 1, and a serial PCM interface. The devices are fabricated using National's advanced double-poly CMOS process (microCMOS). Similar to the TP305X family, these devices feature 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 g6.6V across a balanced 600X load. Also included is an Analog Loopback switch and a TS Complete CODEC and filtering system including: – Transmit high-pass and low-pass filtering – Receive low-pass filter with sin x/x correction m-law or A-law compatible COder and DECoder – Internal precision voltage reference – Internal auto-zero circuitry – Receive push-pull power amplifiers Designed for D3/D4 and CCITT applications Low operating power–typically 70 mW Power-down standby mode–typically 3 mW TTL or CMOS compatible digital interfaces Maximizes line interface card circuit density And we salute our friends in other countries around the world!
