Ordering number : EN4787A
Monolithic Linear IC
LA1836, 1836M
Single-Chip Home Stereo Electronic Tuning IC
Overview
AM: RF amplifier, mixer, oscillator (with ALC), IF
amplifier, detector, AGC, oscillator buffer, tuning
indicator (narrow-band SD), IF buffer output, IF output
for AM stereo
• FM IF: IF amplifier, quadrature detector, band muting,
tuning indicator, IF buffer output, S-meter
• MPX: PLL stereo decoder, stereo indicator, forced
mono, VCO stop function, adjacent channel interference
rejection function (114 kHz), post-amplifier (with
muting function)
Features
• Reduced number of adjustments (adjustment-free MPX
VCO: ceramic resonator adopted)
• Tuning indicator pin (Can be used as a narrow-band stop
signal and as a muting output driver.)
• Variable FM stop sensitivity and band
• Variable AM stop sensitivity
• Built-in AM local oscillator buffer
• Variable AM low cut control
