LTC1069-6
Single Supply, Very Low
Power, Elliptic Lowpass Filter
FEATURES DESCRIPTION n The LTCВ®1069-6 is a monolithic low power, 8th order lowpass
п¬Ѓlter optimized for single 3V or single 5V supply operation.
The LTC1069-6 typically consumes 1mA under single 3V
supply operation and 1.2mA under 5V operation. 8th Order Elliptic Filter in SO-8 Package
Single 3V Operation: Supply Current: 1mA (Typ)
fCUTOFF: 14kHz (Max) S/N Ratio: 72dB
Single 5V Operation: Supply Current: 1.2mA (Typ)
fCUTOFF: 20kHz (Max) S/N Ratio: 79dB
В± 0.1dB Passband Ripple Up to 0.9fCUTOFF (Typ)
42dB Attenuation at 1.3fCUTOFF
66dB Attenuation at 2.0fCUTOFF
70dB Attenuation at 2.1fCUTOFF
Wide Dynamic Range, 75dB or More (S/N + THD),
Under Single 5V Operation
Wideband Noise: 120ВµVRMS
Clock-to-fCUTOFF Ratio: 50:1
Internal Sample Rate: 100:1 APPLICATIONS The cutoff frequency of the LTC1069-6 is clock tunable and it is
equal to the clock frequency divided by 50. The input signal is
sampled twice per clock cycle to lower the risk of aliasing.
The typical passband ripple is В± 0.1dB up to 0.9fCUTOFF . …
