ADS7864YB/250G4

Analog To Digital Converters (ADC) Overview

The ADS7864YB/250G4 is a dual, simultaneous-sampling analog-to-digital converter (ADC) featuring 12-bit resolution and a sampling rate of 500 kS/s per channel. It utilizes successive approximation register (SAR) architecture and accepts differential inputs across six channels. The device operates on a single 5 V supply with voltage ranges from 4.75 V to 5.25 V for both analog and digital domains. It integrates an internal reference and supports external references. The component is housed in a 48-lead TQFP package with dimensions of 7x7 mm and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling capability ensures precise phase alignment between input channels without skew errors.
• Dual SAR ADC architecture provides high-speed conversion with low power consumption.
• Integrated internal voltage reference reduces system complexity and board space requirements.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition
• Medical instrumentation such as ECG and EEG signal processing
• Vibration monitoring and acoustic analysis equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS standards when sourcing. Confirm the /250 designation corresponds to the standard reel packaging format. Ensure the TQFP-48 footprint matches the target PCB layout. Cross-reference the manufacturer part number against current datasheets to confirm active status and pinout compatibility before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of multiple differential signals is required at 500 kS/s. The 12-bit resolution suits applications needing moderate precision with low latency. Consider the 48-pin TQFP package for surface-mount assembly constraints. Evaluate power dissipation limits relative to ambient operating temperatures within the specified industrial range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments ADS7864 family of simultaneous-sampling ADCs. It shares architectural similarities with the ADS7864Y but includes specific manufacturing and compliance suffixes. The series is designed for applications demanding synchronized multi-channel acquisition without external timing synchronization circuits.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7864YB/250 serves as a direct functional equivalent with identical electrical specifications and pinout. Verify that any substitute maintains the same 48-TQFP package dimensions and thermal characteristics to ensure mechanical compatibility.
