ADCS7476AIMFX

Analog To Digital Converters (ADC) Overview

The ADCS7476AIMFX is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with an analog supply voltage range of 2.7V to 5.25V and supports a maximum sampling rate of 1 MSPS. The device features a single-ended input configuration and utilizes a standard SPI or DSP-compatible serial interface for data transfer. Packaged in a compact SOT-23-6 surface-mount footprint, it is designed for applications requiring high precision within a small form factor. The component functions as a standalone system-on-chip solution with an integrated sample-and-hold amplifier.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 12-bit SAR ADC core with a dedicated sample-and-hold circuit for accurate signal capture.
• Supports flexible digital communication through a standard three-wire serial interface compatible with SPI and DSP protocols.
• Operates on a single power supply ranging from 2.7V to 5.25V, simplifying power management in portable systems.

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation
• Industrial process control monitoring
• Battery-powered measurement devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'MFX' against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure that the ordering information matches the required temperature grade and RoHS compliance status. Cross-reference the DigiKey part number 296-35216-2-ND or equivalent distributor identifiers to validate availability and packaging format before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution at 1 MSPS is required in a minimal SOT-23-6 footprint. Consider the ADCS7477AIMFX if 10-bit resolution is sufficient for the application, or the ADCS7478AIMFX for higher speed requirements. Verify that the single-ended input architecture aligns with the sensor output characteristics and that the 2.7V minimum supply voltage meets the system power budget constraints.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADCS747x family of low-power, high-speed ADCs from Texas Instruments. It shares architectural similarities with the ADCS7476AIMF/NOPB and ADCS7476AIMFE/NOPB variants, differing primarily in packaging and reel configurations. The series is designed to replace older discrete solutions by integrating the ADC and reference components into a single monolithic chip.

Analog To Digital Converters (ADC) Replacement Considerations

The AD7477ARTZ-REEL7 from Analog Devices Inc. is documented as a similar replacement option. Verify pinout compatibility and software register settings when transitioning between manufacturers.
