MAX263ACWI+

Overview

The MAX263ACWI+ is a pin-programmable universal and bandpass active filter manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 4.74 V to 12.6 V, with a typical operating voltage of 5 V. The device features two channels and supports a cutoff frequency of 57 kHz. It is housed in a 28-SOIC package designed for surface-mount installation. The component functions reliably across an operating temperature range from 0°C to +70°C.

Feature Summary

• Pin-programmable architecture allows configuration of universal and bandpass filter functions without external components.
• Dual-channel design integrates two independent second-order filter sections on a single chip.

Applications

• Microprocessor-controlled signal processing systems
• Universal switched-capacitor filter implementations
• Bandpass filtering applications requiring programmable center frequencies

Procurement Notes

Verify the specific suffix 'ACWI+' against official documentation to confirm the commercial temperature grade and SOIC-28 package variant. Confirm RoHS compliance status through current manufacturer declarations. Check for end-of-life notifications or discontinuance alerts prior to finalizing procurement plans.

Selection Notes

Select this component when dual-channel programmable filtering is required at frequencies up to 57 kHz. Ensure the system environment remains within the 0°C to +70°C operational range. Verify that the 28-SOIC surface-mount footprint aligns with the PCB layout constraints and assembly capabilities.

Part Context

This part belongs to the MAX263A series of CMOS dual second-order universal switched-capacitor active filters. It shares functional similarities with the MAX263B and MAX263C variants, which differ primarily in temperature ratings and package options. The MAX263 family enables precise filter control via digital inputs.

Replacement Considerations

The MAX263BCWI+ serves as a direct replacement offering identical electrical characteristics but with an extended industrial temperature range. Evaluate thermal requirements to determine if the commercial grade of the ACWI+ suffices or if the BCWI+ variant is necessary.
