BIPOLAR ANALOG INTEGRATED CIRCUIT

The

µPC8002 is a monolithic IC developed for use in digital cordless telephones. Its internal equivalent circuits

comprise a double balanced mixer (DBM), IF amplifier circuit, and RSSI (Received Signal Strength Indicator) circuit.

The

µPC8002 can operate on a wide range of power supply voltages from 2.7 V to 5.5 V, and incorporates a power-

off function, making it ideal for achieving low set power consumption.

The package is a 20-pin plastic shrink SOP (225 mil) suitable for high-density surface mounting.
