ADC128S052CIMTX

Analog To Digital Converters (ADC) Overview

The ADC128S052CIMTX is an 8-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It supports a sampling rate range of 200 kSPS to 500 kSPS with single-ended inputs. The device operates on a supply voltage between 2.7 V and 5.25 V for both analog and digital domains. It features a serial peripheral interface (SPI) compatible digital interface and is housed in a 16-pin TSSOP package. Key performance metrics include a signal-to-noise ratio of 73 dB, differential nonlinearity from -0.9 LSB to +1.3 LSB, integral nonlinearity of 1 LSB, and a gain error of 2 LSB. The component functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix against the manufacturer's current product status documentation. Suffixes such as NOPB indicate RoHS compliance and lead-free material composition. Confirm that the CIMTX designation matches the required tape-and-reel packaging format for automated assembly processes. Ensure the ordering information aligns with the latest datasheet revisions to avoid discrepancies in electrical specifications or pin configurations.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight single-ended channels are required at moderate sampling speeds up to 500 kSPS. The SAR architecture provides low latency compared to delta-sigma alternatives. Verify that the source impedance of the connected sensors remains below the recommended limit to maintain accuracy. Consider the operating temperature range and supply voltage compatibility with the system's power rails before finalizing the design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC128S family of high-speed, multi-channel ADCs from Texas Instruments. It serves as a successor to earlier National Semiconductor products in the same series. The device integrates a sample-and-hold stage with the conversion engine to minimize aperture jitter. It is designed to replace older discrete solutions by providing integrated multiplexing and digital filtering capabilities in a compact surface-mount package.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC128S052CIMTX/NOPB is a direct equivalent offering identical functionality with verified environmental compliance. Other variants within the ADC128S series may offer different sampling rates or resolution but require interface verification.
