MD3902/3905/3910
2/5/10MHz V/F Converters
Models MD3902/3905/3910 are high-
performance, precision 2/5/10MHz full-
scale voltage-to-frequency converters,
intended for those applications that
require maximum performance at the
most economical cost. These converters
feature >126/134/142-dB dynamic range,
±0.01/0.02/0.05%
linearity, and
±5%
overrange capability. The MD3902/3905/
3910 devices feature overall performance
and stability virtually identical to that of
similar units costing 40% or more.
All models accept a -100µV to -10V
full-scale single-ended analog input
signal that is converted to an output signal
whose frequency is proportional to the
full-scale frequency, within 0.01/0.02/
0.05% linearity, using the long-proven
charge-balance technique. The devices
offer 5% overrange capability, and
buffered complimentary TTL-compatible
frequency outputs that will drive capaci-
tive loads as high as 50 pF.
Stability of the MD3902/3905/3910
Series is excellent for V/F converters in
the respective price ranges, with 10µV/°C
typical, 30µV/°C maximum offset and
60 ppm/°C typical, 100 ppm/°C maxi-
mum gain temperature coefficients.
Warm-up time to specified accuracy
is less than two minutes.
In applications where overall system
throughput must be maintained at a
specific rate, or where fixed offset or
different scale voltages would be more
convenient, custom frequencies and/or
custom trimming can be easily accommo-
dated. By increasing the full-scale output
frequency by 10 to 20%, for example,
additional time would be available for
the system microprocessor to access the
results of each conversion. Please contact
the factory to discuss your specific timing
requirements.
All models are packaged in a 1.31" x
0.69" x 0.22" 24-pin ceramic DIL
package. Power dissipation is lower
than 0.65/0.80/0.85 watts, and operation
to specified accuracy is guaranteed over
the 0°C to +70°C temperature range.
