U2510B
All-Band AM/FM Receiver and Audio Amplifier
Description
The U2510B is an integrated bipolar one-chip AM/FM
radio circuit. It contains an FM front end with
preamplifier, FM IF and demodulator, a complete AM
receiver, an AF amplifier and a mode switch for AM, FM
and tape. This circuit is designed for clock radios and
portable radio-cassette recorders.
Features
D Superior FM strong signal behavior by using RF AGC
D Soft mute and HCC for decreasing interstation noise
in FM mode
D Excellent AFC performance (level controlled, both
polarities available)
D Level indicator (LED drive) for AM and FM
D DC mode control: AM, FM and tape
D Wide supply-voltage range and low quiescent current
D High AF output power: 1 W
D Electronic volume control
D Electronic AF bandwidth control (treble and high cut)
D Output stage for headphone and speaker drive
