Quicker conversion is obtained in Teledyne Philbrick 4109 or 4111 A/D converter by restarting converter within a few microseconds after status signal, using surestart circuit shown. Reset pulse is fed to converter when status signal is held at low DC level. When status command is high, oscillator A-B is disabled. If reset pulse is not obeyed and status signal remains low, oscillator starts up until conversion does occur.—R.W.
