Key Featrues
8th-Order Lowpass Elliptic Filter - This high-order filter provides sharp roll-off and excellent stopband attenuation, making it ideal for applications requiring precise frequency separation, such as anti-aliasing in ADCs or post-DAC filtering. Its elliptic response ensures minimal passband ripple, enhancing signal integrity.
Clock-Tunable Corner Frequency (1Hz to 10kHz) - The ability to adjust the corner frequency via an external clock allows for flexible tuning across a wide range of applications, from low-frequency signal processing to higher-frequency filtering needs, improving adaptability in diverse use cases.
Low Power Consumption (2mA Operating, 0.2µA Shutdown) - With a low operating current of 2mA and an ultra-low shutdown current of 0.2µA, this filter is highly efficient, making it suitable for battery-powered or energy-sensitive applications, such as portable devices or IoT sensors.
Single-Supply Operation (+3V or +5V) - The ability to operate from a single +3V or +5V supply simplifies power management and reduces system complexity, making it easier to integrate into both low-voltage and standard voltage systems without additional components.
Low Noise and Distortion (-82dB THD + Noise) - The filter's low noise and distortion levels ensure high-quality signal processing, critical for applications like speech processing or audio filtering, where maintaining signal fidelity is paramount.
