ADCS7477AIMFE/NOPB

Analog To Digital Converters (ADC) Overview

The ADCS7477AIMFE/NOPB is a single-channel, 10-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 digital supply voltages within the same range. The device achieves a sampling rate of 1MSPS and features a single-ended input configuration. Data transfer is handled via a standard SPI or DSP-compatible interface. It is housed in a compact SOT-23-6 surface-mount package and 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 FE against the manufacturer datasheet to confirm pinout and packaging details, as variations exist within the ADCS7477 family. Ensure compatibility with existing PCB footprints for the SOT-23-6 package. Confirm RoHS compliance status if required by project specifications. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution at 1MSPS is sufficient for the application. Consider the SOT-23-6 package constraints regarding thermal dissipation and board space. Compare performance metrics such as SINAD and noise performance against higher-resolution alternatives like the 12-bit ADCS7476 if greater precision is needed. Verify that the single-ended input architecture meets the sensor interface requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADCS747x series, which includes 8-bit, 10-bit, and 12-bit variants sharing similar architectures. The ADCS7477 specifically provides the 10-bit resolution option within this family. It shares design characteristics with other devices in the series, such as the ADCS7476 and ADCS7478, differing primarily in resolution and potentially pin configurations depending on the package suffix.
