TA1249F

The TA1249F is a 2-channel recording amplifier and preamplifier for use in VCR.Since the recording amplifier uses a differential mechanism,it is particularly effective in reducing high-frequency even-ordered distortion.The pre-amplifier also has a differential mechanism and thus also reduces noise.

Features of the TA1249F are:(1)differential drive type recording amplifier;(2)differential input type pre-amplifier;(3)built-in envelope detector for auto-tracking;(4)built-in recording mute circuit;(5)board patterns can easily be shared,due to the high pin compatibility with the TA1250F 4-channel recording amplifier and pre-amplifier,and the TA1273F 6-channel recording amplifier and pre-amplifer.

The maximum ratings of the TA1249F can be summarized as:(1):the characteristic is supply voltage,the symbol is VCC,the rating is 7,the unit is V;(2):the characteristic is input  voltage,the symbol is VIN,the rating is GND-0.3 to VCC+0.3,the unit is V;(3):the characteristic is power dissipation 1,the symbol is PD1,the rating is 378,the unit is mW;(4):the characteristic is power dissipation2,the symbol is PD2,the rating is 780,the unit is mW;(5):the characteristic is operating temperature range,the symbol is Topr,the rating is -20 to 75,the unit is ;(6):the characteristic is storage temperature range,the symbol is Tstg,the rating is -55 to 150,the unit is .
