Product Summary
The LA1137NM-TE-L is a high-performance AM electronic tuner IC offering sophisticated function. The LA1137NM-TE-L is especially suited for use in car radio and home stereo (antenna: loop) application.
Parametrics
LA1137NM-TE-L absolute maximum ratings: (1)Maximum supply voltage VCC max Pin 19 (LA1136N), Pin 15 (LA1137N): 12 V; (2)Output voltage VO1 Pin 6: 13.4 V; (3)VO2 Pin 13 (LA1136N), Pin 10 (LA1137N): 15.5 V; (4)Input voltage VIN Pin 5: 5.6 V; (5)Current drain ICC Pin 15+6+10, V11 = 0 (LA1137N): 60 mA; (6)Flow-out current I20 Pin 20 (LA1137N), Pin 24 (LA1136N): 2 mA; (7)Allowable power dissipation Pd max Ta % 77°C (LA1137N): 680 mW; (8)Allowable power dissipation Pd max1 Independent IC, Ta % 63°C (LA1137NM): 540 mW; (9)Allowable power dissipation Pd max2 With PCB, Ta % 77°C (LA1137NM): 680 mW; (10)Operating temperature: –40 to +85 °C; (11)Storage temperature: –40 to +125 °C.
Features
LA1137NM-TE-L features: (1)Local oscillation buffer output: Facilitates designing of electronic tuner system, frequency display, etc; (2)OSC (with ALC): Improves tracking error because oscillation output is stabilized at a low level (350 mVrms: LA1137N)for varactor diode; (3)MIX: Double-balanced differential MIX meeting the requirements for preventing spurious interference, IF interference; (4)Good characteristic at high input: 130 dBμ inputfm = 400 Hz 80%mod THD = 0.5% typ; (5)High S/N: Good S/N at medium input (55 dB typ). Usable sensitivity: (S/N = 20 dB input): 25 dBμ (when using 2SK715 ); (6)VCC variation compensation: Less variation in gain, distortion: 8 to 12 V.
