The amplifiers in the AV-143 family were designed to serve as booster amplifiers for arbitrary function generators and TTL-level pulse generators. Models AV-143A and AV-143B are linear non-inverting DCcoupled bipolar amplifiers providing peak outputs of +/-10 and +/-20 Volts, with rise times of 10 and 50 ns and voltage gains of 2.5 and 5.0. Models AV-143A and AV-143B have an output impedance of 2 Ohms
while the A1 and B1 versions have an output impedance of 50 Ohms. Models with the "-PS" suffix do not require DC power supplies.
