ta2111n/f/fn 2002-03-05 7 application note 1. am low-cut circuit the am low-cut action is carried out by the bypass of the high frequency component of the positive-feedback signal at the af amp stage. the external capacitor: c 3 by-passes this component. the cut-off frequency f l is determined by the internal resistance 10 k ? (typ.) and the external capacitor c 3 as following ; in the case of the am low-cut function is not needed, set up the value of c 3 over 1 f. in the condition of c 3 1 f, the frequency characteristic has flat response at the low frequency. in fm mode, c 3 is a capacitor for afc low-pass filter circuit. 2. fm detection circuit for the fm detection circuit, detection coil is able to use instead of ceramic discriminator. recommended circuit and recommended coil are as follows. in this case, please take care that v in (lim.) falls a little. turns test frequency c o (pf) q o 1-2 2-3 1-3 4-6 wire (mm ) reference 10.7 mhz 51 45 D D 30 D 0.08 uew toko co., ltd. 600beas-10018z maximum ratings (ta = 25c) characteristics symbol rating unit supply voltage v cc 8 v led current iled 10 ma led voltage vled 8 v ta2111n 1200 TA2111F 400 power dissipation TA2111Fn p d (note 2) 500 mw operating temperature t opr ? 25~75 c storage temperature t stg ? 55~150 c note 2: derated above ta = 25c in the proportion of 9.6 mw/c for ta2111n, of 3.2 mw/c for TA2111F and of 4 mw/c for TA2111Fn.
