DESCRIPTION
The LTC
®
1069-6 is a monolithic low power, 8th order lowpass
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.
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 ± 0.1dB up to 0.9f
CUTOFF
.
The gain at f
CUTOFF
is –0.7dB. The transition band of the
LTC1069-6 features progressive attenuation reaching
42dB at 1.3f
CUTOFF
and 70dB at 2.1f
CUTOFF
. 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 0.4V
RMS
to 1.4V
RMS
, the Signal-to-
(Noise + THD) ratio is ≥70dB. The wideband noise of the
LTC1069-6 is 125μV
RMS
.
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.
