MD3910

MD3902/3905/3910 2/5/10MHz V/F Converters Models MD3902/3905/3910 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. 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 capacitive 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 maximum 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 accommodated. By increasing the full-scale output frequency by 10 to 20%, for example,...
