MAX292EPA+ Lowpass Filter from Maxim Integrated

The MAX292EPA+ is a precision, 8th-order, lowpass, Bessel filter that offers a seamless balance between a nearly linear phase response and a maximally flat amplitude response, making it an ideal choice for applications requiring minimal phase distortion and a smooth roll-off. Manufactured by Maxim Integrated, a leader in analog and mixed-signal engineering, this filter is designed to operate with a single +5V supply or dual ±5V supplies, providing flexibility for various system designs.

Encased in a compact 8-pin DIP package, the MAX292EPA+ is engineered for easy integration into a wide range of electronic systems. With its high-performance characteristics, it is perfectly suited for anti-aliasing and post-DAC filtering applications, as well as for data acquisition systems, signal processing, and medical instrumentation that demand high precision filtering capabilities.

One of the standout features of the MAX292EPA+ is its sharp cutoff characteristics, which are achieved without sacrificing the temporal integrity of the signal. This is due to its Bessel filter topology, which is known for its pure delay characteristics across the frequency spectrum. The filter's -3dB frequency is factory preset at 25kHz, but it can be adjusted to lower frequencies by adding external resistors.

Furthermore, the MAX292EPA+ boasts a low total harmonic distortion (THD) and a high signal-to-noise ratio (SNR), ensuring that signals are filtered with minimal noise and distortion. Its dynamic range is also noteworthy, providing ample headroom for a variety of signal amplitudes.

Key specifications of the MAX292EPA+ include:

• Supply Voltage: Single +5V or Dual ±5V
• Operating Temperature Range: 0°C to +70°C
• Package Type: 8-Pin DIP
• Factory Preset -3dB Frequency: 25kHz (adjustable)
• Filter Type: 8th-Order Bessel Lowpass

In conclusion, the MAX292EPA+ from Maxim Integrated is a high-quality, versatile lowpass filter that meets the needs of various high-precision filtering applications. Its excellent phase and amplitude characteristics make it a top choice for designers looking to maintain signal integrity in their electronic systems.
