| The MAX7408/MAX7411/MAX7412/MAX7415 5th-order, lowpass, elliptic, switched-capacitor filters (SCFs) operate from a single +5V (MAX7408/MAX7411) or +3V (MAX7412/MAX7415) supply. The 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 can be put into a low-power mode, reducing supply current to 0.2μA. Two clocking options are available: self-clocking (through the use of an external capacitor) or external clocking for tighter cutoff-frequency control. An offset-adjust pin allows for adjustment of the DC output level. The MAX7408/MAX7412 deliver 53dB of stopband rejection and a sharp rolloff with a transition ratio of 1.6. The MAX7411/MAX7415 achieve a sharper rolloff with a transition ratio of 1.25 while still providing 37dB of stop-band rejection. Their fixed response limits the design task to selecting a clock frequency.5th-Order, Elliptic Lowpass Filters Low Noise and Distortion: -80dB THD + Noise Clock-Tunable Corner Frequency (1Hz to 15kHz) Single-Supply Operation +5V (MAX7408/MAX7411) +3V (MAX7412/MAX7415) Low Power 1.2mA (operating mode) 0.2μA (shutdown mode) Available in 8-Pin μMAX®/DIP Packages Low Output Offset: ±4mV Applications ADC Anti-Aliasing CT2 Base Stations Post-DAC Filtering Speech Processing More information: | | Filter Type: | Low Pass Filter | Maximum Order: | 5th | Architecture: | Switched Capacitor | Cut-off Frequency: | 1 Hz → 15 kHz | Power Supply Type: | Single | Typical Single Supply Voltage: | 5 V | Number of Circuits: | 1 | Mounting Type: | Surface Mount | Package Type: | DIP | Pin Count: | 8 | Dimensions: | 3.1 x 3.1 x 0.95mm | Height: | 0.95mm | Length: | 3.1mm | Maximum Operating Temperature: | +85 °C | Minimum Operating Temperature: | -40 °C |
