DESCRIPTION

· The MAX7400/MAX7403/MAX7404/MAX7407 are 8th-order, lowpass, elliptic, switched-capacitor filters (SCFs) operating from a single +5V or +3V supply.

· They feature a shutdown mode reducing supply current to 0.2µA and allow corner frequencies from 1Hz to 10kHz.

· Available in 8-pin SO and DIP packages.

FEATURES

· 8th-Order Lowpass Elliptic Filter with low noise and distortion.

· Clock-tunable corner frequency with a 100:1 clock-to-corner ratio.

· Single-supply operation: +5V for MAX7400/MAX7403, +3V for MAX7404/MAX7407.

· Low power consumption: 2mA in operating mode, 0.2µA in shutdown mode.

· Low output offset: ±5mV.

APPLICATIONS

· ADC Anti-Aliasing and Post-DAC Filtering.

· Speech Processing and Air-Bag Electronics.

· CT2 Base Stations.
