LTC1068-25IG#PBF

LTC1068 is a clock-tunable, quad second order, filter building blocks. It contains four matched, low noise, high accuracy 2nd order switched capacitor filter sections. An external clock tunes the centre frequency of each 2nd order filter section. External resistors can modify the clock to-centre frequency ratio. High performance, quad 2nd order, dual 4th order or 8th order filters can be designed with an device family product. Designing filters with a this product is fully supported by FilterCAD™ filter design software for windows. It is used in application such as low pass or high pass filters: LTC1068-200, 0.5Hz to 25KHz; LTC1068, 1Hz to 50KHz; LTC1068-50, 2Hz to 50KHz; LTC1068-25, 4Hz to 200KHz, bandpass or band reject (notch) filters: LTC1068-200, 0.5Hz to 15KHz; LTC1068, 1Hz to 30KHz; LTC1068-50, 2Hz to 30KHz; LTC1068-25, 4Hz to 140KHz etc.
