Maxim Integrated MAX291EWE+T Programmable Universal Active Filters

The MAX291EWE+T from Maxim Integrated is a high-performance, programmable universal active filter that is designed to offer precision filtering applications in a compact and efficient package. This device is part of the MAX291 series, which is renowned for its versatility and ease of use in various signal processing environments.

Constructed with advanced CMOS technology, the MAX291EWE+T is capable of operating in low-pass, high-pass, band-pass, or notch filter configurations. This flexibility allows designers to use the same part for multiple filtering needs, streamlining the design process and reducing inventory overhead. The filter's cutoff frequencies are programmable through an external clock or by using an external resistor, providing further adaptability to a wide range of applications.

The MAX291EWE+T's filter response is of the 8th-order, which ensures a sharp roll-off and excellent selectivity. The device can be configured as a 4th-order filter with two separate filtering blocks, each programmable independently, thereby offering a dual-channel filtering option. This feature is particularly useful in stereo audio applications or when two distinct filtering profiles are required simultaneously.

With a single-supply voltage operation ranging from 4.5V to 5.5V, the MAX291EWE+T is suitable for many electronic systems, including those that run on standard 5V power rails. The device also boasts a wide dynamic range, making it an ideal choice for audio processing, data acquisition systems, anti-aliasing filters, and other signal conditioning applications.

The MAX291EWE+T is offered in a 16-pin SOIC package, which is well-suited for space-constrained applications. Its surface-mount design allows for efficient assembly in automated production environments. Additionally, the MAX291EWE+T is characterized for operation over the extended industrial temperature range (-40°C to +85°C), ensuring reliable performance in harsh environmental conditions.

Overall, the Maxim Integrated MAX291EWE+T programmable universal active filter is a highly versatile and reliable solution for designers seeking a high-quality, easily configurable filter to enhance their signal processing applications.
