MAX30033CTA+T

Overview

The MAX30033CTA+T is a single-channel biopotential analog front-end (AFE) from Analog Devices/Maxim Integrated, designed for high-precision physiological signal acquisition. It features an 18-bit resolution Sigma-Delta converter with a serial SPI interface. The device operates on a supply voltage range of 1.1 V to 2 V and functions within a temperature range of 0°C to +70°C. Packaged in a TQFN-28 surface-mount format, it integrates the necessary circuitry for accurate bio-potential measurement applications.

Feature Summary

• Integrates an 18-bit Sigma-Delta analog-to-digital converter for high-resolution signal processing
• Supports serial communication via SPI interface for system integration
• Optimized for low-voltage operation suitable for portable medical devices

Applications

• Biomedical instrumentation requiring precise bio-potential signal acquisition
• Portable diagnostic equipment utilizing single-channel physiological monitoring
• Medical sensor interfaces demanding high-resolution analog front-end capabilities

Procurement Notes

Verify the specific suffix 'CTA' against official Analog Devices documentation to confirm tape-and-reel packaging and temperature grade specifications. Ensure compatibility with the required 1.1 V to 2 V power supply rails and SPI protocol implementation during design validation.

Selection Notes

Select this component when a single-channel, high-resolution AFE is required for biopotential signals. Consider the 18-bit resolution and low-voltage operation as key differentiators. Verify that the TQFN-28 package fits the board space constraints and that the operating temperature range meets the application environment requirements.

Part Context

This part belongs to the MAX30003 series of biopotential analog front-ends. It serves as a specialized solution for acquiring weak physiological signals, distinguishing itself through its integrated 18-bit conversion capability and compact form factor compared to discrete amplifier solutions.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully if considering other members of the MAX30003 family or competing biopotential AFEs.
