M491B control equivalent, single-chip voltage synthesis tuning system with 1 analog control.
bits. - Modification time of FT D/A is of 1 step every 200ms if issued locally or every 2 received signals from Remote control transmitter. PIN 5 : TUNING D/A (see Figure.
The M491B is a monolithic N-MOS LSI circuit including a Floating-gate Non-Volatile Memory for storage of up to 16 stations. Tuning of the station is performed with a 8192 step D/A converter, using the principle of voltage synthesis. It is designed fo.
