RF5614A

The RF5614A is a kind of monolithic, switched-capacitor bandpass filter. It is available in 8-pin mini-DIP. Each contains a 6-pole Chebyshev ANSI class II bandpass filter with one external input clock trigger. The center frequency of all filters is tunable by the clock frequency. Dynamic range is typically 86 dB and distortion is less than 0.3%.

There are some features of RF5614A as follows: (1)easy to use; (2)no external components required; (3)small size: 8-pin mini-DIP; (4)wide power supply range: ±5 V to ±10 V; (5)dynamic range: up to 86 dB; (6)center frequency range: 9 Hz to 20 kHz. The typical applications include: (1)spectrum analysis (parallel or swept filters); (2)audio filtering; (3)noise analysis; (4)equalization; (5)harmonic analysis; (6)modems.

The following is about the absolute maximum ratings of RF5614A: (1)input voltage-any terminal with respect to substrate, pin (VSS): -0.4 to 21 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. Then is about the device characteristics and operating range limits: (1)supply voltages, VDD: +5 to +10 V; (2)supply voltages, VSS: -5 to -10 V; (3)supply current, ID: 8 mA typ and 25 mA max; (4)center frequency, fo: 9 Hz min and 20000 Hz max; (5)clock frequency, fc: 500 kHz min and 1000 kHz max; (6)input impedance, RI: 3 M min; (7)input impedance, CI: 20 pF max.
