The MAX263BEWI+T is part of the active interface filters available from Maxim Integrated. In order to better understand its application field and working principle, this article will delve into the device’s features and specifications.

MAX263BEWI+T Features

The MAX263BEWI+T is a single chip active filter that operates through a unique combination of capacitors, resistors, and op-amps. This combination allows for a wide range of applications including noise reduction and EMI/RFI filtering. Additionally, the device can be used for both linear and logarithmic filtering, featuring selectable cutoff frequencies from 10 Hz to 10 kHz.

Furthermore, the MAX263BEWI+T features improved signal-to-noise ratio (SNR) through low voltage noise circuitry. This circuitry also enables higher attenuation levels than can be achieved with passive filters, as well as improved EMC and ESD tolerance. The device also features an adjustable operational frequency range between 1 kHz and phase shift adjustment from 0 to 70 degrees.

MAX263BEWI+T Specifications

The MAX263BEWI+T is a single-chip, active filter featuring a wide gain control range of 0.1 to 15 dB. The device’s -3dB cutoff frequency or -3dB steepness is achievable up to 10KHz. It also supports a wide frequency range, beginning at 10 Hz and extending up to 10KHz.

In terms of power consumption, the device requires 9V DC to operate and can be operated along a voltage range of 5.0V to 13.5V. The device features non-polarized input and output signals, both positive and negative polarities. Maximum peak, rms, and differential input and output voltage ranges for the device are ±20V, ±7V and ±17V, respectively.

The device also features a low current consumption of one mA per channel, with current and voltage limiting features, allowing it to be used in mobile applications and in automobiles.

MAX263BEWI+T Working Principle

The MAX263BEWI+T device utilizes switched capacitors and active amplifiers to create an active filter, which is far more efficient than passive filters such as those used in analogue filters. By combining these two technologies, the device allows for the combined benefits of both the active and passive components.

The device operates on a principle where, when the stop-band frequency of the capacitor is higher than the pass-band frequency of the amplifier, the device acts as a low-pass filter, and when the pass-band frequency of the capacitor is higher than the stop-band frequency of the amplifier, it works as a high-pass filter.

The device also incorporates an op-amp circuit, which serves to further amplify the signal, and to ensure that the output is of the highest possible quality. The device also includes active circuits to ensure high attenuation levels, as well as improved EMC and ESD protection, significantly increasing its functionality over passive filters.

Conclusion

The MAX263BEWI+T is an essential component of many active interface filters available from Maxim Integrated. Through its unique combination of active and passive components, the device allows for both high-quality filtering and high attenuation levels, features commonly seen in both consumer and industrial applications. The device’s versatility also makes it suitable for both linear and logarithmic filtering, as well as for use in many different types of power supplies.

By understanding the features, specifications, and working principle of the MAX263BEWI+T, it is possible to identify the many different applications in which the device can be used. In addition, with its low power consumption, versatility, and improved EMC and ESD protection, the MAX263BEWI+T proves to be a reliable component in any active interface filter.
