ADS7815U/1K

Analog To Digital Converters (ADC) Overview

The ADS7815U/1K is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input configuration and operates with a sampling rate of 250 kS/s. The device utilizes a parallel interface for data output and requires both analog and digital power supplies within the range of 4.75 V to 5.25 V. Packaged in a 28-pin SOIC format, it supports an operating temperature range from -40°C to +85°C. Key performance metrics include a signal-to-noise ratio of 83 dB and a total power dissipation of approximately 100 mW.

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 component matches the exact part number to avoid pinout or electrical specification mismatches.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications demanding 16-bit resolution at moderate speeds. Compare against the ADS7815U variant if reel packaging is not required. Evaluate power consumption requirements against the 100 mW dissipation limit. Consider the parallel interface complexity relative to serial alternatives like the ADS7809 if pin count is constrained.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7815 family of 16-bit CMOS ADCs. It shares architectural similarities with other devices in the series but differs in packaging and delivery format. The U/1K designation specifically identifies the SOIC-28 package type combined with tape-and-reel distribution for automated assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7815U serves as the non-reel equivalent. Verify pin compatibility and electrical specifications before substituting. No direct cross-manufacturer replacements are confirmed in the provided data.
