TYPICAL APPLICATION
DESCRIPTION
Single Supply, Very Low
Power, Elliptic Lowpass Filter
TheLTC1069-6isamonolithiclowpower,8thorderlowpass
lter 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.
ThecutofffrequencyoftheLTC1069-6isclocktunableanditis
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 ± 0.1dB up to 0.9fCUTOFF.
The gain at fCUTOFF is –0.7dB. The transition band of the
LTC1069-6 features progressive attenuation reaching
42dB at 1.3fCUTOFF and 70dB at 2.1fCUTOFF. The maximum
stopband attenuation is 72dB.
The LTC1069-6 can be clock tuned for cutoff frequencies
up to 20kHz (single 5V supply) and for cutoff frequencies
up to 14kHz (single 3V supply).
The low power feature of the LTC1069-6 does not penalize
the device’s dynamic range. With single 5V supply and
an input range of 0.4VRMS to 1.4VRMS, the Signal-to-
(Noise + THD) ratio is ≥70dB. The wideband noise of the
LTC1069-6 is 125μVRMS.
Other lter responses with higher speed can be obtained.
Please contact LTC Marketing for details.
The LTC1069-6 is available in an 8-pin SO package.
