The eight-channel ASIC low-noise bipolar transresistance amplifier DOM Ampl
-8.3 has been designed on the basis of BJT-JFET technology for gaseous wire
detectors used in high-energy physics experiments. The amplifier has diffe
rential gain 130 mV/muA at 1 k Omega, input noise 35 and 60 nA r.m.s. at 0
and 60 pF input capacitance, respectively, leading/trailing edge 7 ns, inpu
t resistance approximate to 50 Omega, crosstalks -47 dB, dissipated power 1
60...640 mW/chip for +/- 3...5 V supply. The Ampl-8.3 has been accepted for
upgrading the Forward Angle Muon System of the DO experiment (Fermilab, Ba
tavia, USA), the total number of channels is about 50,000. (C) 2001 Publish
