MAX263ACWI+T

Overview

The MAX263ACWI+T is a pin-programmable universal and bandwidth filter IC from the MAX263 series, manufactured by Analog Devices Inc./Maxim Integrated. It features two independent second-order switched-capacitor filter sections housed in a 28-pin SOIC-Wide (SOICW) surface-mount package. The device operates on a single +5V supply with a maximum voltage of 12.6V and minimum of 4.74V. It supports a center frequency of 57kHz and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Pin-programmable architecture allows configuration for various filter responses including low-pass, high-pass, bandpass, and notch without external components.
• Dual-channel design integrates two independent second-order switched-capacitor filters within a single integrated circuit.
• Universal functionality enables flexible signal processing applications through simple pin connections.

Applications

• Signal conditioning in communication systems requiring specific frequency filtering.
• Instrumentation circuits needing programmable analog filtering solutions.
• Audio processing equipment utilizing switch-capacitor filter topologies.

Procurement Notes

Verify the 'T' suffix indicates tape-and-reel packaging when sourcing this component. Confirm the AC grade specifications against project requirements, specifically noting the commercial temperature range limits. Ensure compatibility with the 28-SOIC-Wide footprint during PCB layout verification.

Selection Notes

Select this part for designs requiring dual-channel programmable filtering without external resistors or capacitors. Compare against MAX263BCWI+ if only a single channel is needed. Verify that the 57kHz center frequency aligns with system bandwidth requirements before finalizing the bill of materials.

Part Context

This component belongs to the MAX263 family of pin-programmable universal filters. It shares architectural similarities with the MAX264, MAX267, and MAX268 but differs in channel count and specific electrical characteristics. The AC variant denotes commercial grade performance suitable for standard industrial environments.

Replacement Considerations

MAX263ACWI is the non-tape equivalent. MAX263BCWI+ offers single-channel functionality. MAX263AEPI+ provides a PDIP-28 through-hole alternative. Verify pinout compatibility before substitution.
