MAX7401CPA+

The MAX7401CPA+ is a 8th order low pass bessel switched capacitor filter (SFC) in 8 pin DIP package. This device draw only draw only 2mA of supply current and in shutdown mode, the supply current reduce to 0.2μA. When using the MAX7401 for anti-aliasing or post DAC filtering, synchronize the DAC and the filter clocks. If the clocks are not synchronized, beat frequencies may alias into the pass band. A high clock to corner frequency ratio allows a simple RC low pass filter with the cut-off frequency set above the SCF corner frequency to provide input anti-aliasing and reasonable output clock attenuation.

• Supply voltage range from 4.5V to 5.5V
• Operating temperature range is -40°C to 85°C
• Low noise and distortion 82dB THD + noise
• Clock tuneable corner frequency (1Hz to 5KHz)
• 100:1 clock to corner ratio
• Low output offset of ±5mV
• Low overshoot and fast settling
• Self clocking (through external capacitor)or external clocking for tighter corner frequency control
• Offset adjust pin for adjustment of the DC output level
