Single 5V, Gain of 1000 4th Order Bandpass Filter
The LTC
®
1060 consists of two high performance, switched
capacitor filters. Each filter, together with 2 to 5 resistors,
can produce various 2nd order filter functions such as
lowpass, bandpass, highpass notch and allpass. The
center frequency of these functions can be tuned by an
external clock or by an external clock and resistor ratio. Up
to 4th order full biquadratic functions can be achieved by
cascading the two filter blocks. Any of the classical filter
configurations (like Butterworth, Chebyshev, Bessel, Cauer)
can be formed.
The LTC1060 operates with either a single or dual supply
from ±2.37V to ±8V. When used with low supply
(i.e. single 5V supply), the filter typically consumes 12mW
and can operate with center frequencies up to 10kHz. With
±5V supply, the frequency range extends to 30kHz and
very high Q values can also be obtained.
The LTC1060 is manufactured by using Linear
Technology’s enhanced LTCMOS™ silicon gate process.
Because of this, low offsets, high dynamic range, high
center frequency Q product and excellent temperature
stability are obtained.
The LTC1060 is pinout compatible with MF10.
