RF6651ANP

The RF6651ANP is a kind of high performance, monolithic, switched-capacitor filter designed for testing telephone and telecommunication systems. The device contains three filters fabricated using double-poly CMOS technology and is available in a 24-pin, 600 mil package. Typical applications include: (1)typical tests this chip can implement are signal-to-noise ratios, harmonic distortion, and idle-channel noise. The low power and improved performance of this chip make it highly suitable for portable test equipment; (2)testing and measurement instrumentation for the US telephone system, both voice and data communication channels; (3)portable, low-power instrumentation.

There are some features of RF6651ANP as follows: (1)combination filter set: C-message filter meeting bell system specifications, 1010 Hz notch filter meeting IEEE specifications,program weighing filter meeting ANSI/IEEE Std 743-1984 specifications; (2)three incommitted op amps for user-designated functions; (3)operates from a TV color burst crystal or from an external TTL/CMOS clock; (4)low power, low noise CMOS switched-capacitor technology; (5)latchup free.

The following is about the absolute maximum ratings of RF6651ANP: (1)input voltage-any terminal with respect to substrate: -0.4 to 15 V; (2)output short-circuit duration-any terminal: indefinite; (3)operating temperature: 0 to 70; (4)storage temperature: -55 to +125; (5)lead temperature (soldering, 10 sec): 300.
