ADS7864Y/2K

Analog To Digital Converters (ADC) Overview

The ADS7864Y/2K is a 12-bit simultaneous sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It features six differential input channels and operates at a sampling rate of 500 kS/s per channel. The device utilizes a Successive Approximation Register (SAR) architecture and supports both internal and external reference configurations. It functions within an analog and digital supply voltage range of 4.75 V to 5.25 V, with a typical power dissipation of 50 mW. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 71 dB, Differential Nonlinearity (DNL) of +/- 0.6 LSB, and Integral Nonlinearity (INL) of 2 LSB. The component is housed in a TQFP-48 package and operates between -40°C and +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling across all six channels ensures precise phase alignment for multi-phase applications.
• Integrated internal voltage reference simplifies board design while supporting external reference options for flexibility.
• Parallel interface enables high-speed data transfer compatible with standard microcontrollers and DSPs.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring synchronized multi-channel data acquisition
• Motor control applications involving three-phase current and voltage monitoring
• Power quality analysis equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status through official datasheets or certification documents prior to integration. Ensure that the procurement source provides valid traceability records for quality assurance purposes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of multiple differential signals is required without external synchronization circuitry. Consider the 500 kS/s throughput and 12-bit resolution limits relative to system bandwidth requirements. Evaluate the TQFP-48 thermal characteristics and pin count against available PCB real estate and routing complexity constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7864 series of simultaneous sampling ADCs from Texas Instruments. It shares architectural similarities with other SAR-based converters but is distinct due to its six-channel parallel output capability. The 'Y' designation indicates the TQFP-48 package type, while '/2K' specifies the reel quantity packaging format.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements are not explicitly confirmed in public documentation. Verify functional equivalence regarding sampling architecture and interface timing if substituting with similar SAR ADCs from other manufacturers.
