Maxim Integrated MAX295ESA+ Lowpass Filter

Introducing the MAX295ESA+, a high-performance, 8th-order, lowpass, elliptic, switched-capacitor filter from Maxim Integrated that significantly simplifies the design of precision filtering applications. This compact and efficient integrated circuit is designed to operate with a single +5V supply, making it an ideal choice for a wide range of applications in the signal processing domain.

The MAX295ESA+ features a fixed cutoff frequency of 100kHz, which is perfectly suited for anti-aliasing before A/D conversion, or for smoothing out signals post-D/A conversion. Its 8th-order filter response ensures a steep roll-off, providing excellent attenuation of unwanted frequencies beyond the passband. The elliptic response of this filter provides a sharp transition band and a high level of stopband attenuation, making it an excellent choice for applications requiring a fast roll-off and minimal signal distortion.

One of the key advantages of the MAX295ESA+ is its ease of use. With no external components required for tuning, this filter can be easily integrated into a variety of designs without the need for complicated adjustments. Additionally, the device features a clock-tuning range of 100:1, allowing for a wide range of clock frequencies and providing designers with flexibility in their system design.

The MAX295ESA+ comes in a small 8-pin NSOIC package, making it suitable for space-constrained applications. Its low power consumption and single supply operation make it an energy-efficient choice for battery-powered devices. Furthermore, the device boasts a dynamic range of 86dB, ensuring that signals are processed with high fidelity.

Whether you're developing audio equipment, communication systems, or precision measurement instruments, the MAX295ESA+ from Maxim Integrated is an excellent choice for your lowpass filtering needs. It combines high-performance filtering capabilities with ease of use and compact form factor, providing a reliable and straightforward solution for your signal processing challenges.
