Overview
The LA1600, being an AM tuner IC placed in a 9-pin SIP,
provides the functions of an AM tuner. It is usable in the
band range up to SW band and is especially suited for use
in low-cost AM radios and radio-controlled receivers.
Functions
• AM : RF amp, MIX, OSC, IF amp, detector, AGC.
Features
• Minimum number of external parts required.
• Low current drain (3.7mA).
• Low supply voltage (1.8V min).
• Adoption of double-balanced mixer.
• Usable in the band range up to SW band.
