5th-Order, Lowpass, Switched-Capacitor Filters MAX7409/MAX7410/MAX7413/MAX7414 General Description Features
The MAX7409/MAX7410/MAX7413/MAX7414 5th-order, ♦
5th-Order Lowpass Filters
lowpass, switched-capacitor filters (SCFs) operate from
Bessel Response (MAX7409/MAX7413)
a single +5V (MAX7409/MAX7410) or +3V (MAX7413/
Butterworth Response (MAX7410/MAX7414)
MAX7414) supply. These devices draw only 1.2mA of supply current and allow corner frequencies from 1Hz ♦
Clock-Tunable Corner Frequency (1Hz to 15kHz)
to 15kHz, making them ideal for low-power post-DAC ♦
Single-Supply Operation
filtering and anti-aliasing applications. They feature a shutdown mode, which reduces the supply current to
+5V (MAX7409/MAX7410)
0.2µA.
+3V (MAX7413/MAX7414)
Two clocking options are available on these devices: ♦
Low Power
self-clocking (through the use of an external capacitor)
1.2mA (operating mode)
or external clocking for tighter corner-frequency control.
0.2µA (shutdown mode)
An offset adjust pin allows for adjustment of the DC out- ♦
