MAX291ESA+ General Description

The MAX291ESA+ is a low-power, monolithic, voltage-controlled bandpass filter in a 8-pin SOIC package. It is designed to receive and amplify signals within a specific frequency range while rejecting signals outside of that range. This bandpass filter has a wide bandwidth of 0.1Hz to 50kHz, making it suitable for a variety of audio and telecommunications applications. It has a high input impedance of 2kΩ, allowing for easy interfacing with other electronic components. The MAX291ESA+ operates on a single 5V supply voltage and has a low power consumption of only 2.5mA, making it ideal for battery-powered applications. It also features a control voltage range of 0V to 5V, allowing for easy tuning of the center frequency of the filter.

Key Features

MAX291ESA+ is a low-power, dual, 8th-order elliptic, switched-capacitor low-pass filter

It operates from a single +5V supply and features a unity-gain frequency of 100kHz, a stopband rejection of -40dB at 1

5MHz, and an adjustable passband gain of up to 10V/V

It comes in an 8-pin SOIC package

Application

Low-power signal conditioning in communication systems

Mobile communication devices

Audio processing applications

Signal filtering and amplification in biomedical devices

It came to tomsk in two weeks. in the work i will check, i will add a review. but the marking is different from the original.

M**y 09/30/2022

Order received after about month and one week (Poland). 100% match with description. Tested with 3.3V power supply. Output voltage drops from 2.3V (dry) to about 1.15V (fully submerged probe) . Measured with standard multimeter. Works great.
