ADCS7477AIMFX/NOPB

Analog To Digital Converters (ADC) Overview

The ADCS7477AIMFX/NOPB is a single-channel, 10-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with an analog and digital 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 an integrated sample-and-hold amplifier. Digital data is transmitted via a standard SPI or DSP-compatible serial interface. It is housed in a compact SOT-23-6 surface-mount package and is rated for operation across an extended industrial temperature range from -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed 1 MSPS SAR ADC with a dedicated sample-and-hold stage for accurate signal capture.
• Supports flexible digital communication through a standard SPI and DSP-compatible serial interface.
• Operates on a wide single power supply ranging from 2.7V to 5.25V for versatile system integration.

Analog To Digital Converters (ADC) Applications

• Portable battery-powered instrumentation requiring low power consumption
• Industrial process control systems with single-ended sensor inputs
• Data acquisition modules in harsh environmental conditions

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'MFX' confirms the SOT-23-6 tape and reel packaging format intended for automated surface-mount assembly. Confirm that the 'NOPB' designation indicates lead-free construction compliant with current RoHS standards. Ensure the operating environment remains within the specified -40°C to +125°C thermal limits to maintain performance specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution and 1 MSPS speed are sufficient for the application. Consider the ADCS7476 variant if 12-bit resolution is required, noting potential differences in noise performance. Verify that the single-ended input architecture aligns with the source signal type, as differential inputs are not supported by this specific model.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADCS747x family of low-power, single-channel SAR ADCs from Texas Instruments. It shares architectural similarities with the ADCS7476 (12-bit) and ADCS7478 (8-bit) variants, offering pin-compatible options for different resolution requirements within the same compact SOT-23-6 footprint.

Analog To Digital Converters (ADC) Replacement Considerations

The AD7477ARTZ-REEL7 from Analog Devices Inc. is documented as a similar replacement option. Verify electrical compatibility and pin alignment before substitution.
