ADS7806U/1K

Analog To Digital Converters (ADC) Overview

The ADS7806U/1K is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input channel and operates with a sampling rate of 100 kS/s. The device utilizes a parallel interface for data output and supports both external and internal reference configurations. It functions within an analog and digital supply voltage range of 4.75 V to 5.25 V, consuming approximately 81.5 mW of power. The component is housed in a 28-pin SOIC package and is rated for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '1K' indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets before finalizing procurement plans. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 100 kSPS speed are sufficient for the application. Consider the parallel interface requirements and 28-pin SOIC footprint during PCB layout. Evaluate if the single-ended input configuration meets the signal source requirements compared to differential alternatives.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS780x family of CMOS sampling ADCs from Texas Instruments. It shares architectural similarities with the ADS7804 and ADS7809 but differs in resolution and interface type. The U/1K designation specifies the SOIC-28 package and reel-based shipping format.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7804U/1K offers similar performance with 12-bit resolution. ADS7809U/1K provides 16-bit resolution with a serial interface. Verify pin compatibility and software changes when substituting these variants.
