DA1855A LeCroy Differential Amplifier

The DA1855A is a differential amplifier from LeCroy. Amplify RF and Microwave signals to measure, test, and design circuits. Applications include radio communications, cellphones, EMI testing, and much more.

Additional Features:

  • Full control from oscilloscope through ProBus interface
  • DC to 100 MHz bandwidth
  • Risetime (typical): <3.5 ns
  • Outstanding 100,000: 1 Common Mode Rejection Ratio (CMRR)
  • Gain of X1 or X10
  • Industry-leading overdrive recovery
  • Low noise
  • Selectable BW limiting
  • Two gain control modes when connected to a LeCroy oscilloscope
  • Built-in Precision Voltage Generator (PVG)
  • Comparator and true differential offset modes

The LeCroy DA1855A is a stand-alone, high-performance 100 MHz differential amplifier. It is intended to act as a signal conditioning preamplifier for oscilloscopes, digitizers and spectrum analyzers, providing differential measurement capability to instruments having only a single-ended input. When used with a DA1855A, oscilloscopes can obtain Common Mode Rejection Ratio (CMRR) and overdrive recovery performance levels previously unobtainable.
