TBA229-5 Datasheet | Siemens Semiconductor Group

Features High AM suppression over a very wide input voltage range High sensitivity Very high symmetry P-DIP-16 The ponent contains two separate limiter amplifiers with FM demodulators and separate AF outputs. Type TBA 229-5 Ordering Code Q67000-A5133 Package P-DIP-16 Circuit Description The ponent contains two separate FM sound IF sections for television stereo applications or for multistandard receivers. Each FM section consists of an eight-stage symmetrical limiter amplifier followed by a coincidence demodulator and an AF pre-amplifier with a low-ohmic output. The ponent features considerably improved AM suppression characteristics with small input signals, as well as a very low frequency deviation between THD min and AM min.
