Working Principles

The MAX7403CSA+ utilizes switched-capacitor technology to implement the 8th-order elliptic filter. Switched-capacitor filters use a series of capacitors and switches to create an equivalent continuous-time filter response. By controlling the timing of the switches, the desired filtering characteristics can be achieved.

The input signal is applied to the IN+ and IN- terminals, and the filtered output is obtained from the OUT pin. The external capacitors connected to the C1, C2, and C3 pins determine the specific filter response.

Detailed Application Field Plans

The MAX7403CSA+ finds application in various audio and communication systems, including: - Audio amplifiers - Wireless communication devices - Digital audio processing equipment - Voice recognition systems - Equalizers and tone control circuits

Its high-performance filtering capabilities make it suitable for applications that require precise frequency response and low distortion.
