ADS7816U

Analog To Digital Converters (ADC) Overview

The ADS7816U is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single differential or single-ended input channel and operates with a sampling rate of 200 kS/s. The device utilizes a 3-wire serial interface compatible with SPI standards. Power consumption is specified at 1.9 mW, supporting low-power applications. It requires an external reference voltage and operates within an analog and digital supply voltage range of 4.5 V to 5.25 V. The component is housed in an SOIC-8 surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Confirm RoHS compliance status as regulatory requirements may vary by production batch. Check for end-of-life notifications or obsolescence warnings before finalizing procurement plans. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between moderate speed and low power is required for single-channel conversion. Compare performance metrics such as SINAD and noise specifications against alternative SAR ADCs in the same family. Evaluate the need for external versus internal reference voltages based on system accuracy requirements. Consider the SOIC-8 footprint constraints during PCB layout design.
