HA12442V

The HA12442V is a kind of IC designed for narrow band width FM-IF and is available for 58 MHz. It provides the following functions: local oscillator, mixer, IF amplifier, FM detector, electric field-strength detector, operational amp (filter amplifier) and queich trigger.

There are some features of HA12442V as follows: (1)the smaller sized PCB by applying vertical type package; (2)small quiescent current; (3)small external parts count; (4)possibe to use both the noise squelch by the operational amplifier and electric field-strength squelch; (5)small electric characteristics change to supply voltage change.

The following is about the absolute maximum ratings of HA12442V: (1)supply voltage, VCC: 8 V; (2)power dissipation, PT: 100 mW; (3)operating temperature range, TOPR: -30 to 75; (4)storage temperature range, Tstg: -55 to 125.
