HIGH PERFORMANCE, LOW NOISE, PROGRAMMABLE VOLTAGE PREAMPLIFIERS FOR A WIDE RANGE OF SMALL SIGNAL APPLICATIONS. THE PRIMARY DIFFERENCES BETWEEN THE TWO MODELS ARE THEIR INPUT IMPEDANCE AND INPUT NOISE. BOTH MODULES MAINTAIN VERY LOW OUTPUT NOISE RESULTING IN EXCEPTIONAL OVERALL NOISE PERFORMANCE, EVEN AT LOW GAIN LEVELS. THE BANDWIDTH OF THESE PREAMPLIFIERS IS INDEPENDENT OF GAIN SETTING SO WAVEFORMS DO NOT CHANGE SHAPE AS THE GAIN IS VARIED. DUAL PARALLEL OUTPUTS (ONE FRONT AND ONE REAR)
