Output Filtering

The output of the TC9400 has a sawtooth ripple super-

imposed on a DC level. The ripple will be rejected if the

TC9400 output is converted to a digital value by an inte-

grating analog-to-digital converter, such as the TC7107

or TC7109. The ripple can also be reduced by increas-

ing the value of the integrating capacitor, although this

will reduce the response time of the F/V converter.

AMP OUT

The sawtooth ripple on the output of an F/V can be

eliminated without affecting the F/V's response time by

using the circuit in Figure 7-5. The circuit is a capaci-

tance multiplier, where the output coupling capacitor is

multiplied by the AC gain of the Op Amp. A moderately

fast Op Amp, such as the TL071, should be used.
