MAX275AEPP+

Overview

The MAX275AEPP+ is a monolithic, low-pass active filter manufactured by Analog Devices Inc./Maxim Integrated. It integrates an operational amplifier with external capacitors to realize a fourth-order Bessel-Thomson response. The device operates from a single +5V supply or dual ±5V supplies. Key electrical parameters include a cutoff frequency of 100kHz and a maximum passband ripple of 0.01dB. It features a high slew rate of 3V/µs and supports input frequencies up to 1MHz. The component is housed in a 20-pin PDIP package.

Feature Summary

• Integrates op amp and passive components for compact implementation
• Provides precise Bessel-Thomson linear phase characteristics
• Supports flexible power supply configurations

Applications

• Data acquisition systems requiring anti-aliasing filtering
• Industrial process control signal conditioning
• Medical instrumentation front ends

Procurement Notes

Verify the specific suffix 'A' against official documentation to confirm temperature range and accuracy grades. Confirm the 'EPP+' designation indicates the lead-free PDIP-20 package variant. Cross-reference the manufacturer's current product status as legacy components may have limited availability or obsolescence notices.

Selection Notes

Select this component when a fixed Bessel response is required without discrete component tolerance variations. Ensure the 100kHz cutoff aligns with system bandwidth needs. Verify that the single-supply operation meets the input common-mode voltage requirements of the application circuit.

Part Context

This part belongs to the MAX274/MAX275 family of integrated active filters. These devices are designed to replace complex discrete RC networks. They offer improved stability and reduced board space compared to traditional multi-stage filter designs.

Replacement Considerations

The MAX274 is the primary counterpart within the same datasheet, differing primarily in cutoff frequency specifications. Verify pin compatibility and functional equivalence before substitution.
