  • 0 ÷ 4 V input range

  • Full 12 bit resolution

  • 1 mV LSB

  • 1.2 µs / ch. conversion time

  • ±0.5 counts integral non linearity

  • ±1% differential non linearity

  • Gate width (Rise Time Protection) programmable from 2 to 32 µs

The Mod. V419 is a 1-unit wide VME 6U module which houses 4 channels of linear gate and stretcher with a multiplexed 12 bit ADC.
The input signals can be square waves, or semi-gaussian positive pulses with a rise time greater than 0.5 µs; it can also convert constant or very slow signals working in sampling mode. A sliding scale technique is featured to improve the differential non linearity. The unit has an A24, D16 VME interface.
