Key Featrues
8th-Order Lowpass Elliptic Filters - This feature provides a steep roll-off and sharp cutoff frequency, making it ideal for applications requiring precise filtering, such as anti-aliasing and DAC post-filtering. Its high-order design ensures superior signal attenuation beyond the cutoff frequency, enhancing overall system performance.
Clock-Tunable Corner-Frequency Range (0.1Hz to 50kHz) - The ability to adjust the corner frequency via an external or internal clock allows for flexible tuning across a wide range of applications, from low-frequency data acquisition to high-frequency voice/data signal filtering, improving adaptability and efficiency.
No External Resistors or Capacitors Required - By eliminating the need for external components, this feature simplifies circuit design, reduces board space, and lowers overall system cost while maintaining high performance and reliability.
Operates with Single +5V or Dual ±5V Supplies - This dual-supply flexibility makes the filter suitable for a variety of power configurations, ensuring compatibility with both single-supply and dual-supply systems, thereby broadening its use cases and ease of integration.
Uncommitted Op Amp for Anti-Aliasing or Clock-Noise Filtering - The inclusion of an uncommitted operational amplifier allows for additional filtering stages, such as anti-aliasing or clock-noise reduction, further enhancing signal quality and system performance in noise-sensitive applications.
