1. On-chip IF count buffer circuit and microprocessorcontrolled 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.

Car Radio Features 1. On-chip IF count buffer circuit and microprocessorcontrolled 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 (pi
