25 kHz cutoff — what it buys the signal chain
The MAX292ESA+ is an 8th-order Bessel low-pass switched-capacitor filter from Maxim Integrated, with a cutoff frequency of 25 kHz. The Bessel characteristic delivers maximally flat group delay, so a pulse or step waveform sees minimal overshoot and ringing — important when the filter sits in a data-acquisition path ahead of an ADC or after a DAC for reconstruction. The switched-capacitor architecture sets the corner frequency by an external clock or an internal oscillator; the 25 kHz figure is the nominal -3 dB point when the clock-to-cutoff ratio follows the datasheet divider.
Supply flexibility: single or dual rails
Runs from a single 4.75 V to 11 V supply, or split supplies of ±2.375 V to ±5.5 V. That covers the common +5 V single-rail and ±5 V analog rails found in industrial signal-conditioning boards and audio processing. A dual-supply connection lets the signal swing around ground without level shifting.
Package and mounting
Housed in an 8-pin SOIC (0.154" width, 3.90 mm body) — the standard narrow SOIC footprint that fits a two-layer PCB without difficulty. Surface-mount only; the 8-SOIC supplier device package matches the package/case entry.
Lifecycle and sourcing posture
Marked as Active in the lifecycle record and ROHS3 compliant.
