What this filter does — and where you'd use it
The Maxim Integrated MAX292CSA+ is an 8th-order Bessel lowpass switched-capacitor filter with a cutoff frequency of 25 kHz. Bessel topology gives maximally flat group delay, so the filter preserves the shape of a pulse or transient waveform — useful in anti-aliasing for data acquisition or signal reconstruction in audio-band measurement chains. The switched-capacitor architecture sets the cutoff via an external clock or the internal oscillator, but the rated 25 kHz is the nominal corner. It runs from a single 4.75 V to 11 V supply or dual ±2.375 V to ±5.5 V rails, packaged in an 8-SOIC.
Active lifecycle — no obsolescence concern
The MAX292CSA+ carries an Active product status.
Package and mounting — standard SOIC, no surprises
The 8-SOIC package (0.154" width, 3.90 mm body) is a common footprint shared across many Maxim filter and interface parts. Surface-mount assembly is straightforward. The supplier device package is listed as 8-SOIC, and the shipping medium is Tube. No thermal pad or exposed paddle to worry about — the part dissipates through the leads and plastic body, so keep the ambient within the standard commercial/industrial range for this package.
