ADS7813UE4

Analog To Digital Converters (ADC) Overview

The ADS7813UE4 is a low-power, serial interface analog-to-digital converter manufactured by Texas Instruments. It features a 16-bit resolution and operates with a single-ended input architecture using a successive approximation register (SAR) structure. The device supports an SPI-compatible serial interface and achieves a sampling rate of 40 kS/s. It functions within an analog and digital supply voltage range of 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 85 dB and a power dissipation of 35 mW. The component is housed in a 16-pin SOIC package and is rated for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-resolution 16-bit SAR ADC core optimized for low-power consumption applications.
• Features a flexible serial interface compatible with standard SPI protocols for simplified system connectivity.
• Includes an internal reference voltage option to reduce external component count and board space.

Analog To Digital Converters (ADC) Applications

• Portable battery-powered instrumentation requiring high resolution and low current draw.
• Industrial process control systems utilizing single-ended sensor inputs.
• Data acquisition modules in environmental monitoring equipment.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the package type corresponds to the SOIC-16 variant rather than the DIP or other pinout configurations. Ensure the ordering part number matches the exact electrical specifications required for the target application design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of 16-bit precision and moderate speed is required without excessive power usage. Compare against the ADS7813U if lead-free certification is not mandatory for the specific market regulations. Evaluate the 40 kS/s sampling rate against the Nyquist requirements of the input signal bandwidth to ensure adequate performance margins.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7813 family of low-power serial ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS7813P but differs in packaging and compliance markings. The UE4 designation specifically identifies the surface-mount SOIC version with environmental compliance attributes distinct from through-hole or non-compliant variants.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7813U is a functional equivalent within the same series, differing primarily in packaging and compliance specifications. Verify pin compatibility and electrical parameter alignment before substitution. Other family members may offer different resolutions or speeds but require careful interface matching.
