5th Order Lowpass Filter

FEATURES  
DESCRIPTIO  
The LTC®1062 is a 5th order all pole maximally flat  
lowpass filter with no DC error. Its unusual architecture  
puts the filter outside the DC path so DC offset and low  
frequency noise problems are eliminated. This makes the  
LTC1062veryusefulforlowpassfilterswhereDCaccuracy  
is important.  
Lowpass Filter with No DC Error  
Low Passband Noise  
Operates DC to 20kHz  
Operates On a Single 5V Supply or Up to ±8V  
5th Order Filter  
Maximally Flat Response  
Internal or External Clock  
Thefilterinputandoutputaresimultaneouslytakenacross  
an external resistor. The LTC1062 is coupled to the signal  
through an external capacitor. This RC reacts with the  
internal switched capacitor network to form a 5th order  
rolloff at the output.  
Cascadable for Faster Rolloff  
Buffer Available  
U
APPLICATIO S  
The filter cutoff frequency is set by an internal clock that  
can be externally driven. The clock-to-cutoff frequency  
ratio is typically 100:1, allowing the clock ripple to be  
easily removed.

single or dual supplies ranging from ±2.5V to ±9V.  
The LTC1062 is manufactured using Linear Technology’s  
enhanced LTCMOSTM silicon gate process.
