ADS7864YB/2K

Analog To Digital Converters (ADC) Overview

The ADS7864YB/2K is a 12-bit simultaneous sampling analog-to-digital converter 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 with an internal reference. It supports parallel digital interfaces and functions within an analog and digital supply voltage range of 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 71 dB, differential nonlinearity of +/- 0.6 LSB, and integral nonlinearity 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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm packaging configuration and reel specifications. Ensure compatibility with system power supply rails operating between 4.75 V and 5.25 V. Confirm thermal management requirements for the TQFP-48 package under maximum ambient temperature conditions of +85°C. Validate that the parallel interface timing aligns with the host controller's capabilities.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of multiple signals is required rather than sequential multiplexing. The 12-bit resolution and 500 kS/s speed suit applications where moderate precision meets real-time processing needs. Consider the parallel interface complexity versus serial alternatives if pin count or board space is constrained. Verify that the SAR architecture latency fits the system's timing budget.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7864 series of simultaneous sampling ADCs from Texas Instruments. The series focuses on providing multiple independent conversion channels within a single integrated circuit. The YB/2K suffix indicates specific tape-and-reel packaging intended for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

Consult official substitution guides for equivalent parts within the same family or alternative manufacturers offering similar simultaneous sampling architectures. Verify pinout compatibility and electrical parameter alignment before implementation.
