Description
The U2860B-M is a dual-channel FM sound demodulator realized with Atmel ’s
advanced bipolar process. All TV FM standards, from 4.5 MHz up to 6.5 MHz
(standard M, B/G, I, D/K) can be processed with high performance. The circuit is
alignment-free and has a minimum number of external components. With 5 V supply
voltage, the U2860B-M is suitable for TV, VCR and multimedia applications.
