MAX294ESA+

Overview

The MAX294ESA+ is an active filter component manufactured by Analog Devices Inc./Maxim Integrated. It functions as an 8th-order, lowpass, elliptic, switched-capacitor filter. The device supports a cutoff frequency of 25 kHz and operates with a single channel. It requires a supply voltage ranging from a minimum of 4.75 V to a maximum of 11 V. The component is designed for surface mount installation in an SOIC-8 package.

Feature Summary

• Provides high-order filtering using switched-capacitor technology
• Delivers elliptic response characteristics for sharp roll-off
• Integrates clock generation capabilities within the circuit

Applications

• Signal conditioning in data acquisition systems
• Anti-aliasing filters for analog-to-digital converters
• Audio processing circuits requiring precise frequency rejection

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead times prior to order placement. Ensure storage conditions meet specified humidity and temperature limits to prevent damage to the integrated circuit during handling and assembly processes.

Selection Notes

Select this component when designing circuits requiring steep attenuation beyond the passband without external inductors. Consider the internal clock frequency requirements relative to the desired cutoff frequency. Evaluate power supply stability within the specified voltage range to maintain consistent filter performance across operating temperatures.

Part Context

This part belongs to the MAX292/MAX294 series of active filters. These components utilize switched-capacitor architecture to achieve complex filter responses in small packages. They are commonly used in applications where space constraints prohibit traditional LC filters while maintaining high precision and stability.
