LA1235 Datasheet | SANYO

Ordering number : EN873G 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 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...
