TEA5757HL Overview
TEA5759HL High selectivity with distributed IF gain Soft mute Signal dependent stereo-blend High impedance MOSFET input on AM Wide supply voltage range of 2.5 to 12 V Low current consumption 18 mA at AM and FM (including tuning synthesizer) High input sensitivity Low output distortion Due to the new tuning concept, the tuning is independent of the channel spacing. GENERAL DESCRIPTION The TEA5757HL; TEA5759HL is a...
TEA5757HL Key Features
- The tuning system has an optimized IC partitioning both from application (omitting interferences) and flexibility (remov
- The tuning quality is superior and requires no IF-counter for stop-detection; it is insensitive to ceramic filter tolera
- In bination with the microcontroller, fast, low-power operation of preset mode, manual-search, auto-search and auto-stor
- The local (internal) controller function facilitates reduced and simplified microcontroller software
- The high integration level (radio and tuning synthesizer on one chip) means fewer external ponents with regard to the mu
- There will be no application considerations for the tuning system, with regards to quality and high integration level, s
- The inherent FUZZY LOGIC behaviour of the Self Tuned Radio (STR), which mimics hand tuning and yields a potentially fast
- The level of the ining signal at which the radio must lock is software programmable
- Two programmable ports
- FM-on/off port to control an external FM front-end ORDERING INFORMATION TYPE NUMBER TEA5757HL TEA5759HL PACKAGE NAME LQF
