GX7793 Replaces AD7793 for Smart Transmitters

Smart Transmitter is a kind of electronic equipment with highly intelligent and automated functions, which is mainly used to modulate various signals and transmit them out. Intelligent transmitter has a strong signal processing capability and can accept different types of input signals, such as audio, video, data, etc., and digitally process and modulate these signals to adapt to different transmission needs.

Equipped with advanced microprocessor and data processing module can ensure the quality and stability of the transmitter signal, the system data processing module can be used 8-channel, 16-bit SAR analog-to-digital converter GX7793, the GX7793 can PIN TO PIN ADI‘s AD7793, with a certain price advantage.

For wireless transmitters, sensor signal acquisition and processing is very important, the GX7793 can ensure the quality and authenticity of the audio signal. GX7793 built-in multi-channel, low-power data acquisition system requires all the devices, including a lossless 16-bit SAR ADC, low crosstalk 8-channel multiplexer, low drift 4.096V reference and buffer, temperature sensor, optional unipolar filters, and a low-cost, low-cost, low-power data acquisition system. The GX7793 has a full complement of components, including a lossless 16-bit SAR ADC, low crosstalk 8-channel multiplexer, low-drift 4.096V reference and buffer, temperature sensor, selectable unipolar filter, and sequence generator for sequential continuous scan channels.
