Overview
The MAX274AEWI+T is a fourth-order, continuous-time active filter manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a single 5V supply and features an external clock input with a maximum frequency of 150kHz. The device integrates four operational amplifiers and two capacitors within a 28-pin Thin Small Outline Package (SO-Wide). Designed for low-power applications, it provides high-performance filtering capabilities suitable for signal processing tasks requiring precise analog signal conditioning.
Feature Summary
- Integrates four op amps and two capacitors to form a complete fourth-order filter solution
- Supports external clock inputs up to 150kHz for flexible frequency tuning
- Operates efficiently on a single 5V power supply
Applications
- Wireless communication systems
- Data acquisition systems
- Instrumentation
Procurement Notes
Verify the specific suffix 'AEWI+T' against official documentation to confirm temperature range and tape-and-reel packaging status. Ensure compatibility with existing board layouts regarding the SO-Wide-28 footprint. Confirm RoHS compliance requirements match the '+T' designation.
Selection Notes
Select this component when a compact, low-power fourth-order active filter is required. Compare performance metrics such as cutoff frequency and Q-factor against other members of the MAX274/MAX275 family. Consider the availability of evaluation kits for initial circuit validation before finalizing the design.
Part Context
This part belongs to the MAX274/MAX275 family of continuous-time active filters. These devices are designed to replace traditional LC or switched-capacitor filters in portable applications. The family offers various order configurations and package options to suit different system constraints.
Replacement Considerations
Check for direct pin-compatible substitutes within the MAX274/MAX275 series. Verify if alternative packages or temperature grades meet the specific application requirements without redesigning the PCB layout.
