ADS7817E/250

Analog To Digital Converters (ADC) Overview

The ADS7817E/250 is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a maximum sampling rate of 200 kS/s and accepts differential analog inputs. The device utilizes an external reference architecture and communicates via a 3-wire serial interface compatible with SPI. It functions within an analog and digital supply voltage range of 4.75 V to 5.25 V. The component is housed in an 8-pin VSSOP package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix E/250 against the manufacturer's current datasheet to confirm package type and operational temperature grade. Ensure the ordering part number matches the required reel or cut tape format if applicable. Cross-reference the RoHS status and moisture sensitivity level with the latest production change notices before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-resolution conversion is required with minimal power usage. The differential input architecture is critical for applications involving noisy environments or small signal amplitudes. Verify that the system can accommodate the external reference requirement and that the 200 kS/s sampling rate meets the bandwidth requirements of the target application.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS7817 family of micro-power ADCs. It shares architectural similarities with other members like the ADS7818 but differs in sampling speed and internal reference availability. The E/250 designation typically indicates the commercial temperature grade and specific packaging variant within the broader product line.
