The LA1806 is a characteristics-improved version of the LA1811, with the same pin assignment and package as those of the LA1811. Improvements are made on the following points:
`Separation (35 dB 48 dB) and its dependence on free-running frequency (Refer to the separate catalog of the LA1805.)
`FM main distortion (0.8% 0.45%)
`AM detection output (approximately 5 dB increased)
The constants on five external parts are changed as LA1811
