ADCS7478AIMFX

Analog To Digital Converters (ADC) Overview

The ADCS7478AIMFX is a single-channel, 8-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 1 MSPS and supports single-ended input signals. The device functions within an analog and digital supply voltage range of 2.7V to 5.25V. It utilizes a 3-wire serial interface compatible with SPI and DSP standards. Packaged in a compact SOT-23-6 surface-mount configuration, the component is rated for operation across an industrial temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'MFX' corresponds to the tape-and-reel packaging format required for automated assembly. Confirm that the NOPB designation indicates lead-free and RoHS compliance if environmental regulations apply to the target deployment. Ensure the ordering quantity aligns with standard reel sizes to avoid cut-tape premiums.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution is sufficient for the application signal chain, offering a trade-off between cost and performance compared to higher-resolution variants like the ADCS7476 or ADCS7477. Verify that the single-ended input topology matches the sensor output type, as differential inputs are not supported by this specific part number.

Analog To Digital Converters (ADC) Part Context

This model belongs to the ADCS747x family of low-power, high-speed SAR ADCs from Texas Instruments. The family includes 12-bit (ADCS7476), 10-bit (ADCS7477), and 8-bit (ADCS7478) variants sharing identical pinouts and interfaces to facilitate design scalability.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same package include ADCS7476AIMFX/NOPB and ADCS7477AIMFX/NOPB, provided the system can accommodate their respective 12-bit and 10-bit resolutions.
