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 ...
Description:
Wurth WE-LPF series Multilayer Chip Low-Pass Filters with
a power capacity up to 3W, low insertion loss and high attenuation in the stop-band. Applications include: RF functions; Wireless communication systems (e.g. DECT; PACS; PHS; GSM; WLAN; Bluetooth).
Description:
The MAX7408/MAX7411/MAX7412/MAX7415 5th-order, lowpass, elliptic, switched-capacitor filters (SCFs)
operate from a single +5V (MAX7408/MAX7411) or +3V (MAX7412/MAX7415) supply. The devices draw only 1.2mA of supply current and allow corner frequencies from 1Hz to 15kHz, making them ideal for low-power post-DAC ...
