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
integrating Analog-to-Digital Converter, such as the
TC7107. The ripple can also be reduced by increasing
the value of the integrating capacitor, although this will
reduce the response time of the F/V converter.
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
capacitance 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.
