Активный фильтр MAX7419EUA+T

Фильтр с переключаемыми конденсаторами , Бесселя, Низких Частот, 5-ый, 1, 4.5 В, 5.5 В, µMAX

The MAX7419EUA+T is a 5th order low pass bessel switched capacitor filter (SFC) in 8 pin µMAX package. This device draw only draw only 3.4mA of supply current and in shutdown mode, the supply current reduce to 0.2µA. When using the MAX7419 for anti-aliasing or post DAC filtering, synchronize the DAC or ADC and the filter clocks. If the clocks are not synchronized, beat frequencies may alias into the desired pass band.

• Supply voltage range from 4.5V to 5.5V
• Operating temperature range from -40°C to 85°C
• Total harmonic distortion and noise is -78dB
• Clock tuneable corner frequency (1Hz to 45KHz)
• 100:1 clock to corner ratio
• Low output offset of ±4mV
• 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
