ADS7861E

Analog To Digital Converters (ADC) Overview

The ADS7861E is a dual-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It supports simultaneous sampling at a rate of 500 kSPS per channel. The device operates with an analog supply voltage range of 2.7 V to 5.25 V and a digital I/O supply range of 1.65 V to 5.5 V. It features a serial interface compatible with standard SPI protocols. The input configuration supports differential or pseudo-differential signals. The component is available in a 24-pin SSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling architecture ensures precise phase alignment between two independent channels without skew.

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 specific suffix against official documentation to confirm packaging and reel specifications. Ensure compatibility with system voltage levels for both analog and digital domains. Confirm pinout alignment with existing PCB layouts before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is required at 12-bit resolution. Compare against the ADS7863 if higher throughput is needed. Evaluate power consumption requirements against the specified supply voltage ranges.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS786x family of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with the ADS7862 and ADS7863 but differs in resolution and sampling speed specifications within the series.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7863 offers 1.5 MSPS sampling rate with identical 12-bit resolution. ADS7862 provides single-channel operation at 500 kSPS. Verify interface compatibility and pinout differences before substitution.
