1 / 9 page Ordering number : EN5688C Monolithic Linear IC For Home Stereo IC with Electronic Tuning Support Single-Chip IC LA1837 Overview The LA1837 is a single-chip AM/FM IF and MPX IC that supports electronic tuning and was developed for use in home stereo systems. It is optimal for use in automatic station selection systems that use the SD and IF counting techniques. Features • On-chip MPX VCO (no external components required). • Adjacent channel interference rejection function (third and fifth order). • Supports both the SD and the IF counting techniques. • The AM and FM SD sensitivities can be set independently. • The AM and FM output levels can be set independently. • Improved AM practical sensitivity and high-input distortion characteristics. Functions • AM : RF amplifier, mixer, oscillator, IF amplifier, detector AGC, oscillator buffer, S-meter, narrowband SD, IF buffer • FM-IF : IF amplifier, quadrature detector, S-meter, Scurve detector, IF buffer output • MPX : PLL stereo decoder, stereo display, forced mono, VCO stop, post amplifier, audio muting, adjacent channel interference rejection function Specifications Maximum Ratings at Ta = 25 °C Parameter Symbol Conditions Ratings Unit Maximum supply voltage VCC max 12 V Allowable power dissipation Pd max Ta ≤ 70°C 550 mW Operating temperature Topr -20 to +70 °C Storage temperature Tstg -40 to +125 °C Specifications of any and all SANYO Semiconductor Co.,Ltd. products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer 's products or equipment.
