ADS7815UE4

Analog To Digital Converters (ADC) Overview

The ADS7815UE4 is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates on dual supplies of +5V and -5V, providing a ±2.5V input range. The device features an integrated sample-and-hold circuit, precision reference, and internal clock, achieving a throughput rate of 250kHz. Key performance metrics include a minimum spurious-free dynamic range (SFDR) of 96dB at a 100kHz input frequency and a signal-to-noise plus distortion ratio (SINAD) of 84dB. It is housed in a 28-lead SOIC package and specified for operation within the industrial temperature range of –25°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix 'E4' corresponds to the required RoHS-compliant packaging and material specifications. Ensure the supply chain documentation matches the active status defined in the official datasheet to avoid obsolete stock.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-speed, 16-bit SAR ADC with a bipolar input range is required. The dual ±5V supply requirement must be accommodated in the system design. Verify that the host microprocessor interface can handle the parallel data bus and timing constraints defined by the CS and R/C signals. Consider external buffering if driving long digital traces.

Analog To Digital Converters (ADC) Part Context

The ADS7815 belongs to the ADS78xx family of CMOS analog-to-digital converters. The 'U' designation indicates the 28-lead SOIC package variant. The 'E4' suffix typically denotes lead finish and environmental compliance attributes according to Texas Instruments naming conventions. This part represents a complete conversion solution integrating the SAR core, S/H amplifier, and reference buffer.

Analog To Digital Converters (ADC) Replacement Considerations

Check for updated revisions within the ADS7815 series. Evaluate other 16-bit SAR ADCs from Texas Instruments or Analog Devices if pin compatibility or supply voltage requirements differ. Ensure any substitute maintains the 250kHz throughput and ±2.5V input range specifications.
