FUNCTIONAL DESCRIPTION
The TEA5710 incorporates internal stabilized power supplies. The maximum supply voltage is 12 V, the minimum voltage
can go down temporarily to 1.8 V without any loss in performance.
The AM circuit incorporates a double balanced mixer, a one pin low-voltage oscillator (up to 30 MHz), a field-strength
dependent indicator output and is designed for distributed selectivity.
The AM input is designed to be connected to the top of a tuned circuit. AGC controls the IF amplification and for large
signals it lowers the input impedance.
The first AM selectivity can be an IFT as well as an IFT combined with a ceramic filter; the second one is an IFT.
The FM circuit incorporates a tuned RF stage, a double balanced mixer, a one-pin oscillator, a field-strength indicator
output and is designed for distributed IF ceramic filters. The FM quadrature detector uses a ceramic resonator.
