5th-order Bessel, 15 kHz cutoff — the anti-aliasing gate
The MAX7413EUA+T is a 5th-order Bessel low-pass switched-capacitor filter with a 15 kHz cutoff frequency. The Bessel characteristic delivers maximally flat group delay — phase distortion across the passband is minimal, which matters when preserving the shape of a pulse or a time-domain signal through the filter. The switched-capacitor architecture sets the cutoff via an external clock or internal oscillator — the 15 kHz figure is the nominal corner; the actual roll-off tracks the clock frequency.
8-uMAX/uSOP — footprint and supply posture
Package is 8-uMAX/uSOP (also listed as 8-TSSOP/MSOP, 3.00 mm width). The surface-mount land pattern follows the MSOP-8 IPC-7351 standard.
