ADS7862YB/2K

Analog To Digital Converters (ADC) Overview

The ADS7862YB/2K is a dual-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features simultaneous sampling capabilities with a maximum sampling rate of 500 kS/s per channel. The device utilizes a parallel interface for data output and supports differential input types. It operates 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 and a signal-to-noise and distortion ratio of 70 dB. The component is housed in a TQFP-32 package and includes an internal reference. It is designed for operation across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling architecture ensures precise phase alignment between channels
• Integrated internal reference reduces external component count
• Parallel interface facilitates high-speed data transfer

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition
• Medical instrumentation such as ECG and EEG monitoring devices
• Data acquisition modules for test and measurement equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '2K' indicates reel packaging when sourcing from distributors. Confirm RoHS compliance status through official manufacturer documentation or authorized supplier certificates. Ensure the TQFP-32 package variant matches the target PCB footprint design requirements before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is required at 12-bit resolution. Compare DNL specifications against application tolerance levels; note that the YB variant may differ slightly from the standard Y version. Ensure the system power supply remains stable within the 4.75 V to 5.25 V range to maintain specified SNR performance.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7862 series of high-speed, low-power ADCs. It shares architectural similarities with other members like the ADS7864 but differs in channel count. The YB suffix typically denotes a specific tape-and-reel packaging option compared to bulk or cut-tape variants found in other SKUs within the same family.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7862Y/2K is a related variant within the same product line. Verify if the DNL specification differences between the Y and YB suffixes impact the specific application requirements before substitution.
