The LTC
filter, which provides a linear phase response over its
entire passband. An external TTL or CMOS clock pro-
grams the filter’s cutoff frequency. The clock to cutoff
frequency ratio is 75:1 (Pin 10 at V
V
frequency is 95kHz. No external components are needed.
The LTC1064-3 features low wideband noise and low
harmonic distortion even for input voltages up to 3V
In fact the LTC1064-3 overall performance competes with
equivalent multiple op amp RC active realizations. The
LTC1064-3 is available in a 14-pin DIP or 16-pin surface
mounted SOL package. The LTC1064-3 is fabricated using
LTC’s enhanced analog CMOS Si-gate process.
The LTC1064-3 is pin compatible with the LTC1064-1,
LTC1064-2 and LTC1064-4.
