TCA240 DIP16 - Doubly balanced modulator and similar items

The TCA240 is a monolithic integrated circuit used primarily as a doubly balanced modulator/demodulator for general-purpose electronic applications. Key Features Function: It is designed to operate as a modulator, mixer, switch/chopper, AM or FM quadrature synchronous demodulator, phase comparator, and differential amplifier. Design Flexibility: The circuit is structured to offer highly flexible circuit design possibilities, thanks to the excellent coupling and temperature tracking of the internal transistors. Alternative IC: It is considered Philips/Siemens' answer to the competitor Motorola MC1496, although it is not pin-for-pin compatible. RF Applications: It is also suitable for radio frequency (RF) applications, with some circuits effectively using it well beyond 100 MHz. Package: It is typically available in a DIP-16 (Dual In-line Package with 16 pins) plastic package. Temperature Range: Specified for an extended ambient operating temperature range from -40C to 105C. Applications Due to its versatility, the TCA240 has been employed in various circuits, including: Modulators and Demodulators: Its primary function, used in various analog communication systems. Mixers: For combining signals at different frequencies in RF applications. Differential Amplifiers: Leveraging the excellent matching of the internal transistors. Phase Comparators: Useful in phase-locked loop (PLL) circuits.
