The TDA2540 from Philips is an integrated circuit designed as an IF amplifier with demodulator and AFC capabilities. It is suitable for use in color and black and white television receivers, compatible with both PNP and NPN tuners. This component is intended for the reception of negative or positive modulation CCIR standards.
Key electrical characteristics include a typical supply voltage of 12V and a typical supply current of 50mA. The IF input voltage sensitivity is typically 85μVRMS at 38.9MHz, with a typical IF voltage gain control range of 64dB. The video output voltage for white is typically 2.7VPP. The device also features a signal-to-noise ratio of 58dB at 10mV input voltage.
The TDA2540 incorporates several functions such as a gain-controlled amplifier, synchronous demodulator, white spot inverter, video preamplifier with noise protection, switchable AFC, and AGC with noise gating. It is available in a DIP16 plastic package, suitable for through-hole mounting.
Absolute maximum ratings include a supply voltage of 13.8V and a power dissipation of 900mW. The operating ambient temperature range is from 0°C to 70°C.
