LA1776M

Ordering number : ENN8085 www.DataSheet4U.com SANYO Semiconductors DATA SHEET LA1776M Overview Functions FM front end FM IF Noise canceller Multiplex AM up-conversion FM/AM switch MRC Monolithic Linear IC Single-Chip Tuner IC for Car Radios The LA1776M integrates all six blocks required in a car radio tuner on a single chip. Feature Reduced noise in the mixer and amplifier blocks for improved performance Increased FM front end mixer dynamic range for improved three signal characteristics Improved AM practical sensitivity and saturated signal-to-noise ratio S-meter sample-to-sample variations can be improved by using the FM S-meter shift function (Fixed resistors can be used for the SD, keyed AGC, muting on adjustment, muting attenuation, SNC, and HCC.) High-speed searching can be implemented using the FM band mute time constant switching function. Superb listenability provided by improved medium and weak field noise canceller characteristics. Improved separation temperature dependency characteristics Excellent FM S-meter voltage linearity Noise rejection improved by modifications to the NC circuit Sample-to-sample variation correction circuit (zapping) in the FM IF circuit Stopping at stations with heavy interference is prevented by increasing the AM wide AGC sensitivity by 10 dB during seek operations Built-in anti-birdie filter Any and all SANYO products described or contained herein do not have specifications that can handle ap...
