LTC1068IN#PBF General Description

The LTC1068IN#PBF product, part of the LTC1068 family, consists of four monolithic clock-tunable filter building blocks. These filters feature four matched 2nd order switched-capacitor filter sections that are characterized by low noise and high accuracy. The center frequency of each filter section can be adjusted using an external clock, with different products offering varying clock-to-center frequency ratios (200:1, 100:1, 50:1, or 25:1). By utilizing external resistors, designers can modify the clock-to-center frequency ratio to meet their specific design requirements. With an LTC1068 product, users have the flexibility to create high-performance quad 2nd order, dual 4th order, or 8th order filters. To aid in the design process, FilterCAD™ filter design software for Windows provides comprehensive support for designing filters with LTC1068 products
