Conditions AM: fi = 1 MHz; m = 0.3; fm = 1 kHz; VP = 3.0 V; measured in Fig.4 with S1 in position B and S2 in position A, unless otherwise specified. Conditions FM: fi = 100 MHz; Df = 22.5 kHz; fm = 1 kHz; VP = 3.0 V; measured in Fig.4 with S1 in position B and S2 in position A, unless otherwise specified. High input sensitivity: 1.6 mV/m (AM), 2.0 mV (FM) for 26 dB S/N. The TEA5710 is a high performance Bimos IC for use in AM/FM radios. All necessary functions are integrated: from AM and FM front-end to detector output stages. FM-RFI : FM-RF aerial input (input impedance typ. 50 W), AM-IF1I : input from IFT or ceramic filter (input impedance typ. 3 kW), AM-MIXER : open-collector output to IFT, FM-MIXER : output to ceramic IF filter (output impedance typ. 330 W), 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. AM CHARACTERISTICS fi = 1 MHz; m = 0.3; fm = 1 kHz; VP = 3.0 V; measured in Fig.4 with S1 in position B and S2 in position A, unless otherwise specified.
