General Description
The MAX270/MAX271 are digitally-programmed, dual second-order continuous-time lowpass filters. Their typical dynamic range of 96dB surpasses most switched capacitor filters which require additional filtering to remove clock noise. The MAX270/MAX271 are ideal for anti-aliasing and DAC smoothing applications and can be cascaded for higher-order responses.

FEATUREs
♦ Continuous-Time Filtering - No Clock Required

♦ Sections Independently Programmable: 1kHz to 25kHz
♦ 96dB Dynamic Range
♦ No External Components
♦ Cascadable for Higher Order
♦ Low-Power Shutdown Mode
♦ Track-and-Hold (MAX271)
