Essential for digital processing! Noise is below 60%, distortion has significantly reduced second-order components, and power consumption has also been reduced by about 10%.

This device is an improved version of the frequency-selective, rapid cutoff characteristic low-pass filter PGF-8, with significant enhancements in noise and distortion achieved through a review of its components and circuits. Noise in the high-frequency range has been reduced to below 60%, and the second harmonic distortion has been significantly decreased. The average current consumption has also decreased by about 10%. It features a low distortion rate filter that can handle up to 12 frequencies through a switch. This filter switches frequencies using a 4-bit (line) control signal. Its primary application is as an anti-aliasing low-pass filter for AD converters. The filter characteristics are of the 8th order Chebyshev type, available in two types: 130dB/oct and 100dB/oct. ◇◆◆◇◆━━━━━━━━━━━━━━━━━━━━━━━━━ For more details on "distortion rate" and other specifications, please take this opportunity to download the "latest specification sheet" or feel free to contact us. ━━━━━━━━━━━━━━━━━━━━━━━━━◇◆◆◇◆
