LTC1560-1 - 1MHz/500kHz Continuous Time/ Low Noise/ Lowpass Elliptic Filter

Description

The LTC ®1560-1 is a 5th order, continuous-time, lowpass filter.

The elliptic transfer function of the LTC1560-1 was carefully chosen to reach a compromise between selectivity, for antialiasing applications, and transient response.

LTC1560-1 1MHz/500kHz Continuous Time, Low Noise, Lowpass Elliptic Filter FEATURES s s s s s s s 5th Order, 1MHz Elliptic Filter in SO-8 Package Pin Selectable 1MHz/500kHz Cutoff Frequency Signal-to-Noise Ratio (SNR): 75dB Signal-to-Noise Ratio with – 63dB THD: 69dB Passband Ripple (fCUTOFF = 1MHz): ± 0.3dB Stopband Attenuation Better Than 60dB No External Components Required U APPLICATIONS s s s either 500kHz (Pin 5 to V +) or 1MHz (Pin 5 to V –). When programmed for 1MHz, the passband ripple is typically ± 0.2dB up to 0.55fCUTOFF and ± 0.3dB to 0.9fCUTOFF. The transition band gain is – 24dB at 1.4fCUTOFF and – 51dB at 2fCUTOFF. Stopband attenuation is 63dB at 2.43fCUTOFF and above, remaining at least 60dB to 10MHz with proper board layout.
