A150 Pulse Amplitude Discriminator

The A150 is a high performance hybrid pulse amplitude discriminator developed for use in precision pulse spectroscopy.

Its low power dissipation (17 mW) and high speed (> 4 MHz) make it ideal for space flight use. The A150 is packaged in a standard 14 Pin hybrid DIP.

NOTE: The A150 has been discontinued. Some parts from prior programs and old date codes may be available. Contact Amptek for more information.
