Integrierte Innovation


The SCOPE IC has been developed for visualization of electrical signals. The function principle of a one-channel storage oscilloscope and a minimum of external wiring permit both use in smallest measuring devices for service and test field and placement near the front panels in operator consoles and switch cabinets.

  • A/D conversion with 6-bit resolutionen
  • Time base programmable from 50ns..3,27ms (at 20 MHz CLK)
  • Trigger Modes: Auto, Internal+/-, External +/-
  • 5 discrete trigger levels
  • Internal SRAM for 128 values
  • Input Range ± 0.5V
  • Shift of base line by adjustable control voltage
  • Single supply 5 Volts
  • Power Down
  • Package PLCC44
  • Technology CMOS C4A 1,2µm

After loading of the parameters of
time basis, trigger level and trigger
mode into the control registers,
the recording is started as soon as
the trigger condition occurs. It
ends when 128 data words have
been written from the A/D
converter into the internal SRAM.
An externally connected
microcontroller can read the
stored data and prepare it for
an LC display or for transfer via
an interface.
