LTC1164ACN - Low Power, High Performance, Octal 8th Order Lowpass Filter

The LTC1164ACN is a highly integrated solution designed by Linear Technology for advanced signal processing applications requiring multiple filtering stages. This precision octal 8th order lowpass filter features a maximally flat Bessel frequency response, which provides a near-ideal delay characteristic, making it perfect for applications that demand minimal signal distortion and a smooth phase response.

Encased in a 24-pin narrow DIP package, the LTC1164ACN offers a compact footprint for space-constrained designs. It operates with a single or dual power supply ranging from ±2.37V to ±8V, which allows for flexible integration into various system architectures. The low power consumption of the device, typically 2.5mA per filter section, makes it an excellent choice for battery-powered devices and energy-efficient systems.

The LTC1164ACN is characterized by its ease of use, requiring no external components for fixed frequency operation. This plug-and-play aspect significantly simplifies the design process and accelerates time to market. The filter’s cutoff frequencies are factory set, which means they can be directly implemented into the signal chain without the need for additional tuning or calibration.

With eight independent 8th order lowpass filter sections, the LTC1164ACN is capable of handling multiple channels simultaneously, making it ideal for multi-channel applications such as audio processing, data acquisition systems, anti-aliasing filters, and other sophisticated industrial or consumer signal processing tasks. The high order of the filter ensures a sharp cutoff characteristic, which is essential for rejecting unwanted high-frequency noise and preserving the integrity of the desired signal.

Overall, the LTC1164ACN from Linear Technology stands out as a robust, high-performance filtering solution that delivers precision and reliability in a user-friendly package. Its combination of low power operation, high filter order, and ease of integration make it a top choice for designers looking to enhance their signal processing capabilities without compromising on efficiency or space.
