LA1145 Features

Features

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.
