Datasheet Summary
TCA770
II TCA770D
I.F. LIMITER-AMPLIFIER with very low current consumption
The TCA 770 is a limiter-amplifier with a balanced f. m. detector and an audio preamplifier intended for a frequency range of 100 kHz to 500 kHz with narrow band f. m. The circuit is especially intended for use in portophone sets, where low current consumption and high sensitivity are important.
