Overview
19-4766; Rev 1; 9/98 5th-Order, Lowpass, Switched-Capacitor Filters General Description The MAX7409/MAX7410/MAX7413/MAX7414 5th-order, lowpass, switched-capacitor filters (SCFs) operate from a single +5V (MAX7409/MAX7410) or +3V (MAX7413/ MAX7414) supply.
These devices draw only 1.
2mA of supply current and allow corner frequencies from 1Hz to 15kHz, making them ideal for low-power post-DAC filtering and anti-aliasing applications.
They feature a shutdown mode, which reduces the supply current to 0.
2µA.
Two clocking options are available on these devices: 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.
The MAX7409/MAX7413 Bessel filters provide low overshoot and fast settling, while the MAX7410/MAX7414 Butterworth filters provide a maximally flat passband response.
Their fixed response simplifies the design task to selecting a clock frequency.
