ADS7817EC/250

Analog To Digital Converters (ADC) Overview

The ADS7817EC/250 is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with differential input signals and supports a sampling rate of 200 kS/s. The device utilizes an external reference type and communicates via a 3-Wire or SPI serial interface. It functions within an analog and digital supply voltage range of 4.75 V to 5.25 V. The component is housed in a VSSOP-8 package and is designed for surface mount installation. It maintains an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'EC/250' against the manufacturer's current datasheet to confirm package type and tape-and-reel quantity specifications. Ensure that the external reference circuitry matches the required voltage levels for optimal performance. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to align with assembly line standards.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is sufficient for the application. Consider the 200 kS/s sampling rate limit for bandwidth requirements. Verify that the system can accommodate an external reference voltage source, as internal references are not included in this specific part variant. Evaluate the VSSOP-8 footprint constraints against available PCB space.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS7817 family of micro-power sampling ADCs. It shares architectural similarities with other members like the ADS7816 and ADS7818 but differs in specific features such as reference integration and input configurations. The EC/250 designation indicates a specific commercial grade version with defined packaging and testing parameters distinct from automotive or industrial extended variants.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7817UB is a related variant within the same family offering similar performance characteristics. Check pinout compatibility and reference configuration differences before substitution. Other family members may require different external components due to varying reference types.
