ON LA1145M-MPB-E

Overview

1. On-chip IF count buffer circuit and microprocessor   controlled switch circuit for ETR.2. Compared to the LA1140, the LA1145, 1145M offer:   1 Improved signal meter output linearity;   2 Improved band mute temperature stability;   3 Improved S/N ratio;   4 Improved sound quality at weak signal input when    noise is present, and;   5 Improved AMR characteristics during weak signal    input.3. Reduced parts’ count simplifies design:   1 On-chip IF count buffer circuit;   2 On-chip SD circuit — sensitivity can be set      independently of soft mute characteristics, and;   3 Variable S-meter gradient — three pin S-meter output      (pins 5, 16 and 17) facilitates independent control of      SNC and HCC.
