The MAX7423EUA is an advanced integrated circuit (IC) component manufactured by Maxim Integrated. This device is a third-order, low-pass, elliptic switched-capacitor filter operating with a single +5V power supply. It is designed to offer precision filtering capabilities for various applications such as audio, video, and data communications.
Key features of the MAX7423EUA include a 3rd order, low-pass, elliptic switched-capacitor filter with 0.1dB pass-band ripple and 62dB stop-band attenuation. This allows for effective noise suppression and signal conditioning. The device has a fixed cutoff frequency of 2.8kHz, making it suitable for filtering out high-frequency noise from audio and video signals.
The IC component integrates a clock generator with a frequency of 500kHz, eliminating the need for external clock sources. This simplifies the design and reduces component count. Additionally, the MAX7423EUA provides a high input impedance, allowing for easy interfacing with various input sources.
One notable feature of this device is its ability to be easily cascaded with other MAX7423EUA filters, enabling the creation of higher-order filter designs. This cascade capability is achieved through the use of a single resistor and capacitor. This feature provides flexibility in designing complex filter structures to meet specific application requirements.
The MAX7423EUA operates with an extended temperature range from -40°C to +85°C, ensuring reliable performance in harsh environmental conditions
