May 1997 ML2111* Universal Dual High Frequency Filter GENERAL DESCRIPTION The ML2111 consists of two independent switched capacitor filters that operate at up to 150kHz and perform second order filter functions such as lowpass, bandpass, highpass, notch and allpass.
All filter configurations, including Butterworth, Bessel, Cauer, and Chebyshev can be formed.
The center frequency of these filters is tuned by an external clock or the external clock and resistor ratio.
The ML2111 frequency range is specified up to 150kHz with ±5.
0V ±10% power supplies.
Using a single 5.
0V ±10% power supply the frequency range is up to 100kHz.
These filters are ideal where center frequency accuracy and high Qs ...
