ADN2891 THEORY OF OPERATION LIMITING AMPLIFIER Input Buffer The ADN2891 limiting amplifier provides differential inputs (PIN/NIN), each having single-ended, on-chip, 50 Ω termina- tion. The amplifier can accept either dc-coupled or ac-coupled signals; however, an ac-coupled signal is recommended. Using ...
