Description
The MAX291/MAX292/MAX295/MAX296 are easy-to-use, 8th-order, lowpass, switched-capacitor filters that can be set up with corner frequencies from 0.1Hz to 25kHz (MAX291/MAX292) or 0.1Hz to 50kHz (MAX295/MAX296).
Features
- o 8th-Order Lowpass Filters:

o Clock-Tunable Corner-Frequency Range: 0.1Hz to 25kHz (MAX291/MAX292) 0.1Hz to 50kHz (MAX295/MAX296)
o No External Resistors or Capacitors Required
o Internal or External Clock
o Clock to Corner Frequency Ratio: 100:1 (MAX291/MAX292) 50:1 (MAX295/MAX296)
o Low Noise: -70dB THD + Noise (Typ)
o Operate with a Single +5V Supply or Dual ±5V Supplies
o Uncommitted Op Amp for Anti-Aliasing or ClockNoise Filteri.
