LTC1064

Low Noise, Fast, Quad

Universal Filter Building Block

FEATURES

DESCRIPTIO

■

Four Filters in a 0.3 Inch Wide Package

The LTC^®1064 consists of four high speed, low noise

switched-capacitor filter building blocks. Each filter build-

ing block, together with an external clock and three to five

resistors can provide various 2nd order functions like

lowpass, highpass, bandpass and notch. The center fre-

quency of each 2nd order function can be tuned with an

external clock, or a clock and resistor ratio. For Q ≤ 5, the

center frequency range is from 0.1Hz to 100kHz. For Q ≤

3, the center frequency range can be extended to 140kHz.

Up to 8th order filters can be realized by cascading all four

2nd order sections. Any classical filter realization (such as

Butterworth,Cauer,BesselandChebyshev)canbeformed.
