Accurate Switched-Capacitor Technology
The high frequency resistor programmable universal
active filter is a CMOS chip that can be configured
for Lowpass, Bandpass, Highpass, Elliptic, Notch or
Allpass filters using external resistors. The filters
come in one (8 pin) or two (16 pin) section ver-
sions. The device is a switched-capacitor filter
using a topology that requires fewer pins, less
power consumption and provides higher frequency
performance than other switched-capacitor universal
8 or 16 pin DIP or SOIC
0.5 to over 20
6.25:1 to over 50:1
active
filters. The clock to corner ratio as well
as the Q are set by external resistors.
Ap p lica tio n s _______________________
Depending on the filter type and response, from
zero to nine external resistors are needed for each
section. The sections may be cascaded to realize
higher order filters.
General Purpose Filtering
Portable Equipment
Instrumentation
The devices have a selectable nominal sample to
corner ratio of either 6.25 to 1 or 12.5 to 1 and
come in either a low power version (fo<100 kHz)or
a higher power version (fo<500kHz). The devices
are double sampled to reduce the clock frequency
by a factor of two.
