Ordering number : EN873G LA1235 Monolithic Linear IC FM IF System Applications Overview The LA1235 is a high integrated IC developed for use in high S/N, low distortion FM IF system applications. This IC features S/N = 88dB, distortion factor = 0.015% and has almost all functions required for FM tuner IF stage. The IF amplifier and limiter stage consist o.
S/N = 88dB, distortion factor = 0.015% and has almost all functions required for FM tuner IF stage. The IF amplifier and limiter stage consist of 6 stages of double ended differential amplifier having an excellent AMR, and this stage is followd by the signal meter driver which consists of 4 stages of level detector, thereby creating extended linearity up to strong input. The FM detector stage consists of a double balanced quadrature detector to which a low frequency preamplifire and a muting controller are attached. The muting drive stage consists of an OR circuit for weak signal muting drive .
