ADC141S626CIMMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC141S626CIMMX/NOPB is a 14-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments, which acquired National Semiconductor. It features a single differential input channel and supports sampling rates from 50 kSPS to 250 kSPS. The device operates with an analog supply voltage range of 2.7 V to 5.5 V and a digital supply voltage range of 2.7 V to 5.5 V. It utilizes a 3-wire SPI-compatible serial interface for data output. Key performance metrics include a signal-to-noise ratio (SNR) of 93 dB and low power consumption characteristics suitable for battery-operated systems.

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer designation as Texas Instruments due to the acquisition of National Semiconductor. Confirm the package type is MSOP-10 and ensure the suffix /NOPB indicates lead-free and RoHS compliance. Check for AEC-Q100 qualification if automotive reliability is required for the specific revision.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-resolution conversion is needed at moderate speeds up to 250 kSPS. Ensure the application can accommodate an external reference voltage between 1.0 V and VA. Consider the MSOP-10 package constraints for PCB layout and thermal management compared to larger packages.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC141S626 family, which includes variants like the ADC141S628. It shares architectural similarities with other SAR ADCs in the portfolio but is distinct in its 14-bit resolution and specific power-saving features. The transition from National Semiconductor branding to Texas Instruments requires attention to updated datasheets and documentation sources.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADC141S628, which offers multiple channels. For single-channel replacements, verify compatibility with the ADC161S626 series, noting differences in resolution and sampling speed. Ensure pinout and electrical specifications match before substitution.
