ADS7817U/2K5G4

Analog To Digital Converters (ADC) Overview

The ADS7817U/2K5G4 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a high-impedance fully differential analog input and operates with a single +5V supply, consuming 2.3mW at a 200kHz sampling rate. The device utilizes an external reference voltage ranging from 100mV to 2.5V to define the input span. Communication is handled via a synchronous 3-wire serial interface compatible with SPI. The component is housed in an SOIC-8 package and is rated for operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix /2K5G4 corresponds to the Tape and Reel packaging format containing 2500 devices per reel. Confirm the specific performance grade (ADS7817U, UB, or UC) required for the application, as linearity specifications vary between grades. Ensure the SOIC-8 package type matches the PCB footprint design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a differential input is required to reject common-mode noise. The external reference allows flexibility in setting the LSB size between 49µV and 1.22mV. Note that lower reference voltages increase the relative impact of internal noise and offset errors. Ensure the driving source impedance is low enough to charge the 15pF input capacitance within 1.5 clock cycles.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7817 family of micro-power sampling ADCs. The 'U' designation indicates the SOIC-8 plastic package. The '/2K5' suffix specifies the tape and reel quantity of 2500 units. Other variants in the family include the PDIP-8 (P) and MSOP-8 (E) packages, as well as different performance grades (B and C) offering tighter linearity specifications.
