LTC1562-2

tend to scale with R2.) At high fO these resistors fall below
4k, heavily loading the outputs of the LTC1562-2 and
leading to increased THD and other effects. At the other
extreme, a lower fO limit of 20kHz reflects an arbitrary
upper resistor limit of 1M
. The LTC1562-2’s MOS input
circuitry can accommodate higher resistor values than
this, but junction leakage current from the input protection
circuitry may cause DC errors.
The 2nd order transfer functions HLP(s), HBP(s) and
HHP(s) (below) are all inverting so that, for example, at DC
the lowpass gain is – HL. If two such sections are cas-
caded, these phase inversions cancel. Thus, the filter in the
application schematic on the first page of this data sheet
is a dual DC preserving, noninverting, rail-to-rail lowpass
filter, approximating two “straight wires with frequency
selectivity.”
Figure 4 shows further details of 2nd order lowpass,
bandpass and highpass responses. Configurations to
obtain these responses appear in the next three sections.
Basic Lowpass
When ZIN of Figure 3 is a resistor of value RIN, a standard
2nd order lowpass transfer function results from VIN to V2
