An active filter is a type of analog circuit that implements an electronic filter to a signal using active components such as an amplifier. When an amplifier is included in a filter design or application, it can improve the predictability and performance of the filter.
Types of Active Filters
Brand Pass Filters
Brand Reject Filter
High Pass Filter
Low pass Filter
Quad Filters and Universal Filters are devices that can be programmed to perform one of the other types of active filters
Description:
The LTC1068 product family consists of four monolithic
clock-tunable filter building blocks. Each product contains four matched, low noise, high accuracy 2nd order switched-capacitor filter sections. An external clock tunes the center frequency of each 2nd order filter section. The LTC1068 products differ only in their clock-to-center frequency ratio. The ...
Description:
Linear Technology filter ICs present continuous time and
switched capacitor filters that offer flexibility as well as being easy to use. The active filters can support low pass and a wide range of frequencies. They are suitable for use in Phased locked loop, smoothing filters, discrete RC active filter replacement ...
