AM/FM stereo DTS radio circuit
Product specification
TEA5712; TEA5712T
FEATURES
• Wide supply voltage range: 1.8 or 2.1 to 12 V
• Low current consumption: 16 mA at AM, 17 mA at FM
• High selectivity with distributed IF gain
• LED driver for stereo indication
• High input sensitivity: 1.6 mV/m (AM), 2.0 µV (FM) for
26 dB S/N
• Good strong signal behaviour: 10 V/m at AM,
500 mV at FM
• Low output distortion: 0.8% at AM, 0.3% at FM
• Signal level output
• Soft mute
• Signal dependent stereo
• IF output signals available for IF counting
• Designed for simple and reliable printed-circuit board
layout
• High impedance MOSFET input on AM.
APPLICATIONS
• Portable AM/FM stereo radio
• Mini/midi receiver sets
• Digitally tuned personal headphone radio.
DESCRIPTION
The TEA5712 is a high performance Bimos IC for use in
digitally tuned AM/FM stereo radios. All necessary
functions are integrated: from AM and FM front-end to AM
detector and FM stereo output stages.
