TYPICAL APPLICATION

DESCRIPTION

Single Supply, Very Low

Power, Elliptic Lowpass Filter

TheLTC®1069-6isamonolithiclowpower,8thorderlowpass

ﬁlter 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 ﬁlter responses with higher speed can be obtained.

Please contact LTC Marketing for details.

The LTC1069-6 is available in an 8-pin SO package.
