**Teledyne LeCroy Differential Amplifier DA1855A**

The DA1855A 1 channel and DA1855A-PR2 2 channels are stand-alone, high-performance 100MHz differential amplifiers. They act as signal conditioning preamplifiers 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. The DA1855A has a bandwidth of 100MHz but any one of the three 3-pole bandwidth limit filters can be selected to reduce bandwidth to 20MHz, 1MHz or 100kHz to limit noise above the frequency of interest.
