FreqDev 1.0 Hz to 100 kHz Fixed Frequency D68 & DP68 Series 32 Pin DIP 8-Pole Filters provide high performance linear active filtering with a broad range of transfer functions and corner frequencies.
The document describes the D68 and DP68 Series of small 8-pole fixed-frequency precision active filters. These units are available in a compact 32-pin DIP package and provide high-performance linear active filtering without requiring external components or adjustments.
The datasheet details various transfer functions including Butterworth, elliptic, Bessel, and constant delay characteristics for both low-pass (D68L/DP68L) and high-pass (D68H) models. It provides comprehensive product specifications such as passband ripple, stopband attenuation rates, cutoff frequency stability, total harmonic distortion, and noise levels.
