ADS7817UB

Analog To Digital Converters (ADC) Overview

The ADS7817UB is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a 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. It communicates via a synchronous 3-wire serial interface compatible with SPI. The ADS7817UB is housed in an SOIC-8 package and supports an operating temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and check for moisture sensitivity labeling prior to soldering. Ensure storage conditions comply with JESD22-A113 standards to prevent lead frame corrosion or package delamination during assembly.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS7817UB when a differential input is required to reject common-mode noise in noisy environments. Choose this part over single-ended variants if system ground loops are present. Ensure the external reference voltage source can supply the peak current demands during bit decisions without significant droop.

Analog To Digital Converters (ADC) Part Context

The ADS7817UB belongs to the ADS7817 family of micro-power ADCs. It shares architectural similarities with the ADS7817P and ADS7817E but differs in packaging. The 'UB' suffix specifically denotes the SOIC-8 plastic small-outline package variant within the Texas Instruments product line.
