Активный фильтр MAX7401CSA+

Фильтр с переключаемыми конденсаторами , Бесселя, Низких Частот, 8-ой, 1, 4.5 В, 5.5 В, NSOIC

The MAX7401CSA+ is a 8th order low pass bessel switched capacitor filter (SFC) in 8 pin NSOIC 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 0°C to 70°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
