Description
Dymec’s Frequency to Voltage Converters are considerably lower in
cost and easier to use in complex circuits than conventional Digital to
Analog Converters of comparable accuracy. Utmost flexibility is al-
lowed in the form factor of the input frequency waveform, and a spe-
cial internal timing section makes these Frequency to Voltage Convert-
ers insensitive to variations in input wave duty cycle.
Models 9110, 9010, and 9200 are available in three Temperature
Compensation ranges. They provide extremely tight linearity, accu-
racy, and performance levels, and are complementary to Dymec’s high
performance Series 8000 Voltage to Frequency Converters, with no
compromise in system performance.
