| NTE1495 Integrated Circuit AM RF Mixer, IF Amplifier Description: The NTE1495 is a monolithic integrated circuit in a 15-Lead Staggered SIP type package. This device is suitable for use as an AM tuner in automotive radio receivers, specifically where compact mounting is required and contains an RF amplifier, mixer, IF amplifier, and two types of AGC circuits. Features: D High Sensitivity D Excellent Two-Signal Selectivity Characteristics which Permits Receiving any Weak Signal Without Interference from the Next Strongest Signal D Wide AGC Range Provided by Two AGC Circuits (Delay Type) Employed in the IF and RF Stages, in Addition to the Ability to Withstand Large Input and to the Yeild of High S/N Ratio Absolute Maximum Ratings: (TA = +25C unless otherwise specified) Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16V Input Voltage, Vi . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7VP-P Power Dissipation (TA = +75C), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 310mW Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -20 to + 75C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -40 to +125C Recommended Operating Conditions: (TA = +25C unless otherwise specified) Parameter Operating Supply Voltage Operating Ambient Temperature Symbol VCC TA Test Conditions Min 9 -20 Typ 13 - Max 16 +75 Unit V C Electrical Characteristics: (TA = +25C, VCC = 13V, f = 1MHz, fmod = 400Hz, MOD = 30%, RL = 10k unless otherwise specified) Parameter Circuit Current Maximum Sensitivity Signal-to-Noise Ratio Detector Output Total Tarmonic Distortion Symbol ICC MS S/N O THD Test Conditions At No Signal Input level (i) at which detector output o gets 20mVrms i = 24dBV i = 74dBV i = 126dBV Min 18 - 15 40 - Typ 26 10 20 60 0.4 Max 34 17 - 90 3.0 Unit mA dBV dB mVrms % Tuner Performance Characteristics: (TA = +25C, VCC = 13V, f = 1MHz, fmod = 400Hz, MOD = 30%, RL = 10k unless otherwise specified) Parameter Maximum Sensitivity Usable Sensitivity Detector Output Detector Distortion Signal-to-Noise Ratio Overload Distortion IF Rejection Image Rejection Selectivity Tweet Test Conditions Input voltage at which detector output voltage is 20mVrms Input voltage at which S/N Ratio is 20dB Resistors connected to Pin5 are 47k and 33k, i = 74dBV i = 74dBV i = 74dBV i = 126dBV f = 1MHz, o = 20mVrms, IF = 450kHz f = 1MHz, o = 20mVrms, f + 2 IF f = 1MHz, f = 10kHz i = 74dBV 2 IF = 900kHz 3 IF = 1350kHz Pin Connection Diagram (Front View) Value 10 24 60 0.4 50 0.4 67 80 31 45 50 Unit dBV dBV mVrms % dB % dB dB dB dB dB 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 IF Output Bypass AGC Input IF Input Mixer Input Mixer Output GND GND RF Output Bypass Bypass RF Input VCC OSC Input OSC Output .767 (19.5) .110 (2.79) .259 (6.57) 1 15 .500 (12.7) .468 (11.8) .100 (2.54) .100 (2.54) .700 (17.78) .039 (1.0) .100 (2.54) |
