The TDA2546A is a monolithic integrated circuit developed by NXP Semiconductors for quasi-split-sound processing, including 5.5 MHz demodulation, specifically for television receivers.
This IC features a 3-stage gain-controlled IF amplifier with an AGC circuit, and a reference amplifier and limiter amplifier for vision carrier processing. It also includes a linear multiplier for quadrature demodulation. The second IF stage incorporates an 8-stage limiter amplifier, a quadrature demodulator, an AF amplifier with de-emphasis, and an AV switch.
Key electrical characteristics include a typical supply voltage of 12V and a typical supply current of 57mA. The minimum IF vision carrier input voltage is typically 150 µV. The device is housed in an 18-lead DIL plastic package (SOT 102).
Operating within an ambient temperature range of 0°C to 70°C, the TDA2546A is suitable for various television receiver applications requiring robust sound processing.
