ADS803E/1KG4

Analog To Digital Converters (ADC) Overview

The ADS803E/1KG4 is a high-speed, high dynamic range, 12-bit pipelined Analog-to-Digital Converter (ADC) manufactured by Texas Instruments. It features a sampling rate of 5 MSPS and supports both differential and single-ended input types. The device operates with an analog supply voltage ranging from 4.7V to 5.3V and includes an internal reference. Key performance metrics include a Differential Nonlinearity (DNL) of +/- 0.75 LSB and an Integral Nonlinearity (INL) of +/- 2 LSB. It utilizes a parallel data interface and is housed in a 28-SSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance when sourcing. Confirm the package type matches the 28-SSOP specification. Check current availability status as this component may be obsolete or end-of-life. Ensure the supplier provides valid datasheets matching the Texas Instruments original documentation. Validate that the operating temperature range meets the application requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications demanding 12-bit resolution at 5 MSPS speeds. Consider the parallel interface requirement for system compatibility. Evaluate power consumption against available thermal management solutions. Compare DNL and INL specifications against system accuracy needs. Assess the need for external versus internal reference options based on noise sensitivity.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS80x series of high-performance ADCs from Texas Instruments. It shares architectural similarities with the ADS803E but differs in packaging and compliance markings. The series is designed for applications requiring fast conversion rates and high dynamic range. Other variants in the family may offer different sampling rates or pin configurations.

Analog To Digital Converters (ADC) Replacement Considerations

ADS803E/1K is a manufacturer-recommended alternative with similar specifications. Verify pinout compatibility before substitution. Check if the non-G4 suffix affects RoHS compliance requirements. Ensure the replacement maintains the same 28-SSOP package dimensions.
