Working Principle

The MAX261BEWG consists of two high-speed trans-impedance amplifiers, a low-noise bias current source, and a low-offset voltage amplifier. The combined components form a complete low-noise signal conditioning solution. The two trans-impedance amplifiers provide high-speed and low-output impedance. The amplifiers’ output is free from low-frequency noise, making them an ideal choice for high-resolution applications. The low-noise bias current source is used to bias the trans-impedance amplifiers, providing a low-noise output for applications that require minimal output variance. The low-offset voltage amplifier is designed to provide low input-voltage offset and high input-current rejection, making it suitable for use in applications where a low-noise input signal is necessary.

The MAX261BEWG is designed to operate on a wide voltage and current range, with a supply voltage of 2.5V to 12V and a quiescent current draw of 1µA or less. The device is designed to consume minimal power, making it suitable for battery-operated applications. The trans-impedance amplifiers have a maximum gain of 100V/V and a bandwidth of up to 5GHz. The device is also capable of operating over the full temperature range of -40°C to +85°C, making it suitable for use in harsh environment applications.

The MAX261BEWG is a versatile active filter device that provides a low-cost and low-power solution for a wide range of analog signal processing applications. With its two high-speed trans-impedance amplifiers, low-noise bias current source, and low-offset voltage amplifier, the MAX261BEWG is an ideal choice for medical, automotive, and industrial applications. Its small size and wide operating range make it a perfect choice for space-constrained applications, allowing designers to minimize system size and power consumption while still delivering high performance.
