The LTC
®
1164-5 is a monolithic 8th order filter; it approxi-
mates either a Butterworth or a Bessel lowpass response.
The LTC1164-5 features clock-tunable cutoff frequency
and low power consumption (4.5mA with ±5V supplies
and 2.5mA with single 5V supply).
Low power operation is achieved without compromising
noise or distortion performance. With ±5V supplies and
10kHz cutoff frequency, the operating signal-to-noise
ratio is 86dB and the THD throughout the passband is
0.015%. Under the same conditions, a 77dB signal-to-
noise ratio and distortion is obtained with a single 5V
supply while the clock feedthrough is kept below the noise
level. The maximum signal-to-noise ratio is 92dB.
The LTC1164-5 approximates an 8th order Butterworth
response with a clock-to-cutoff frequency ratio of 100:1
(Pin 10 to V
–
) or 50:1 double-sampled (Pin 10 to V
+
and
Pin 1 shorted to Pin 13). Double-sampling allows the input
signal frequency to reach the clock frequency before any
aliasing occurrence. An 8th order Bessel response can
also be approximated with a clock-to-cutoff frequency
ratio of 140:1 (Pin 10 to ground). With ±7.5V supply, ±5V
supply and single 5V supply, the maximum clock fre-
quency of the LTC1164-5 is 1.5MHz, 1MHz and 1MHz
respectively. The LTC1164-5 is pin-compatible with the
LTC1064-2 and LTC-1064-3.

Note 1: Absolute Maximum Ratings are those values beyond which life of
the device may be impaired.
Note 2: Connecting any pin to voltages greater than V
+
or less than V
–
may cause latch-up. It is recommended that no sources operating from
external supplies be applied prior to power-up of the LTC1164-5.
Note 3: All gains are measured relative to passband gain. The filter cutoff
frequency is abbreviated as f
