Double Amplifier-Discriminator Board (A2DB-32)

2 modes of amplification:

K1= 65 mV/uA

K2=420 mV/uA

Designed both for wire and strip R/O

Analog and 2 digital (ECL, LVDS) outputs

Low noise: I noise r.m.s = 38nA

Low cross talk < -45 dB

Status: “table-top” tested, ready for production (80 with spares)
