ADS7815U

Analog To Digital Converters (ADC) Overview

The ADS7815U 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 transfer and requires both analog and digital power supplies within the 4.75 V to 5.25 V range. Key performance metrics include a signal-to-noise ratio of 83 dB and an integral nonlinearity of +/- 4 LSB. It is housed in a SOIC-28 package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'U' corresponds to the standard SOIC-28 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the supply chain source provides valid traceability records for quality assurance purposes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed 16-bit ADC is required. Compare against the ADS7805 if lower sampling rates are acceptable. Verify that the system can accommodate the parallel interface timing requirements. Ensure the power supply rails match the specified 5 V nominal operation for optimal performance.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7805/ADS7815 family of 16-bit CMOS analog-to-digital converters. The family shares similar architectural characteristics but differs in sampling speeds and interface options. The ADS7815 represents the higher-speed variant within this specific series, designed for applications demanding faster throughput than the base ADS7805 model.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7815U/1K is a reel-packaged variant of the same functional device. Direct substitutes may include other 16-bit SAR ADCs with parallel interfaces, though pin compatibility and timing specifications must be verified against the original datasheet.
