Universal Dual High Frequency Filter
BLOCK DIAGRAM
1
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 are needed.
The ML2111 is a pin compatible superior replacement for
MF10, LMF100, and LTC1060 filters.
