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 are needed.

The ML2111 is a pin compatible superior replacement for

MF10, LMF100, and LTC1060 filters.
