National Semiconductor LM3065

LM3065 television sound system
general description
The LM3065 is a monolithic integrated circuit
television sound system that requires a minimum
of external components for operation. It includes
three stages of I F limiting, an FM detector, an
electronic attenuator or volume control, an audio
amplifier-driver, and a temperature stable regulated power supply. Volume control is accomplished by varying bias levels of the electronic
attenuator with a potentiometer between pin 6
and ground. Because no audio signal is present in
this control, hum and noise pickup are easily filtered. Unshielded wire may be used for volume
control.

Features include:
• Electronic attenuator: replaces conventional ac
volume control
• Volume reduction range: >60 dB
• Sensitivity: 3 dB limiting voltage-200 J1V typically
• High stability
• Low harmonic distortion
• Audio drive capability: 6 mA p-p
• Undistorted audio output voltage: 7V p-p
• Differential peak detector
• Simple detector alignment: one coil
• Internal zener diode regulator
• Excellent AM rejection-50 dB typo @ 4.5 MHz

This part came to us as part of a lot of surplus stock from a large Milspec type OEM and has been kept in storage for some time, we have therefore classified it as ‘new other’. It is however still a good serviceable component, the photographs are representative of it’s excellent condition, and, as with all our products it comes with a full guarantee.
