MAX7424CUA+, Фильтр с переключаемыми конденсаторами, Баттерворт, Низких Частот, 5-ый, 1, 2.7 В, 3.6 В, MAX

The MAX7424CUA+ is a 5th order low pass, switched capacitor filter in 8 pin µMAX package. This butterworth filters provides a maximally flat pass band response, making them ideal for instrumentation applications that require minimum deviation from the DC gain throughout the pass band. It operates with a 100: 1 clock to corner frequency ratio. Two clocking options are available on this device, self-clocking (through the use of an external capacitor) or external clocking for tighter corner-frequency control. An offset adjust pin allows for adjustment of the DC output level. It uses an alternative approach which is to emulate a passive network using switched-capacitor integrators with summing and scaling. It is used in DAC post filtering, air-bag electronics and CT2 base stations.
