The LeCroy DA1855A is a standalone high-performance 100 MHz differential amplifier designed for precise signal conditioning and differential measurements. It offers selectable bandwidth filters (20 MHz, 1 MHz, 100 kHz) to limit noise, and an internal Precision Voltage Generator (PVG) with a ±15.5 V DC range for differential offset or comparator functions. With gain selection of ×1 or ×10 and input attenuation of ×10, it supports a common-mode dynamic range up to ±155 V and recovers from overdrive within 100 ns.
Ideal for high-dynamic-range measurements, this amplifier is essential for capturing accurate signal data across varying test conditions and voltage levels.
