The LTC1563-2IGN#PBF is a highly integrated active RC lowpass filter produced by Linear Technology, now part of Analog Devices. This advanced component is designed to meet the stringent requirements of today's high-performance signal processing applications without the need for clock-driven switched capacitors.
Featuring a 4th-order filter with a fixed frequency response, the LTC1563-2IGN#PBF is specifically configured to provide a Butterworth characteristic, ensuring maximally flat passband without ripples. This makes it an ideal choice for applications requiring a clean and stable signal pass-through such as anti-aliasing for data acquisition systems, audio signal processing, and various communications equipment.
Key Features:
- Filter Order: 4th-order active RC lowpass filter
- Filter Response: Butterworth for maximally flat amplitude response
- Cutoff Frequency: Adjustable from 1kHz to 150kHz
- Supply Voltage: Single 5V supply
- Dynamic Range: 84dB at 1kHz
- Low Noise: 90μV RMS noise at 1kHz
- Package: 16-lead narrow SSOP package
- Part Number: LTC1563-2IGN#PBF
The LTC1563-2IGN#PBF is also noted for its ease of use, requiring no external components to set the filter's corner frequency. This corner frequency is easily set by a single external resistor, or it can be adjusted on-the-fly, which adds to the versatility of the design. The filter's dynamic range is maintained over the entire audio frequency range, making it exceptionally well-suited for high-fidelity audio applications.
In terms of design flexibility, the LTC1563-2IGN#PBF offers a simple, compact solution that reduces the complexity and component count of traditional filter designs. Its single-supply operation and integrated features make it an economical choice for a wide range of filtering applications, while the small footprint of the SSOP package allows for space-saving on the PCB.
