MD3802/3805/3810 2/5/10MHz V/F, F/V Converters Models MD3802/3805/3810 are highperformance, precision 2/5/10MHz fullscale 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. All models accept a -100µV to -10V fullscale analog input signal that is converted to an output signal whose frequency is proportional to.

MD3802/3805/3810 2/5/10MHz V/F, F/V Converters Models MD3802/3805/3810 are highperformance, precision 2/5/10MHz fullscale 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. All models accept a -100µV to -10V fullscale 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 buffered complimentary TTL-compatible frequency outputs that will drive capacitive loads as high as 50 pF. Models MD3802/3805/3810, in addition to functioning as V/F converters, can also be used as F/V converters. In this configuration, the converters will accept frequencies from dc to 2/5/10MHz and will produce proportional single-ended output voltages from 0V to -10V. 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 accommodated. 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 0.80" x 0.15" 24-pin ceramic DIL package. Power dissipation is lower than 0.75/0.85/1.0 watts, and operation to specified accuracy is guaranteed over the 0°C to +70°C temperature range.
