MAX292ESA

Overview

The MAX292ESA is an active filter manufactured by Analog Devices Inc./Maxim Integrated, belonging to the MAX292 series. It is an 8th-order lowpass switched-capacitor filter with a cutoff frequency of 25 kHz. The device operates on a single supply voltage ranging from 4.75 V to 11 V, with a typical operating voltage of 5 V. It features one channel and is housed in a 16-pin SOIC package suitable for surface mount installation. The component supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Provides high-order filtering performance through an integrated 8th-order lowpass architecture
• Utilizes switched-capacitor technology for precise frequency control without external inductors
• Operates reliably within a wide single-supply voltage range

Applications

• Signal conditioning in data acquisition systems
• Anti-aliasing filters in analog-to-digital conversion stages
• Noise reduction in sensor interface circuits

Procurement Notes

Verify the specific suffix and tape-and-reel packaging options when sourcing, as availability may vary by region. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before finalizing procurement plans. Ensure the selected variant matches the required industrial temperature specifications for the intended deployment environment.

Selection Notes

Select this component when a fixed 25 kHz cutoff frequency is required for 8th-order attenuation. Compare against other MAX29x variants if different cutoff frequencies or order configurations are needed. Ensure the system clock frequency aligns with the filter's operational requirements for optimal performance.

Part Context

This part belongs to the MAX292 family of switched-capacitor filters, which offers various cutoff frequencies and filter responses. It serves as a compact alternative to discrete RC networks, providing precise filtering characteristics in a small surface-mount package suitable for space-constrained electronic designs.

Replacement Considerations

Check for MAX292 variants with different cutoff frequencies or packages. Verify compatibility with existing PCB footprints and clocking requirements when substituting.
