Lecroy DA1855A

This amplifier is a stand alone, high performance 100MHz 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 this unit, oscilloscopes can obtain Common Mode Rejection Ratio (CMRR) and overdrive recovery performance levels previously unobtainable.

Optional probes increase the maximum input signal and common mode ranges in proportion to their attenuation ratio but do not exceed their maximum input voltage rating.

This unit output is carefully limited to ±500mV, so that the oscilloscope is not overdriven by large inputs.

This allows many oscilloscopes to directly measure the settling of D/A converters with 14-bit (60 ppm) precision, better than any other differential comparator.
