ADS7864Y/250

Analog To Digital Converters (ADC) Overview

The ADS7864Y/250 is a 12-bit, six-channel simultaneous sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes successive approximation register (SAR) architecture and features a parallel interface for data output. The device operates with both analog and digital supply voltages ranging from 4.75 V to 5.25 V. It supports a sampling rate of 500 kS/s per channel and accepts differential input signals. Key performance metrics include a signal-to-noise ratio (SNR) of 71 dB, a differential nonlinearity (DNL) of +/- 0.6 LSB, and an integral nonlinearity (INL) of 2 LSB. The component is housed in a TQFP-48 package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling across all six channels ensures precise phase alignment for multi-phase applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'Y/250' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure that the ordering information matches the required package type and temperature grade. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of multiple differential signals is required at 12-bit resolution. It is suitable for designs needing a 500 kS/s throughput with low power consumption of 50 mW. Consider the TQFP-48 package constraints and parallel interface requirements during PCB layout. Verify that the system voltage aligns with the 4.75 V to 5.25 V operating range.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS7864 series of simultaneous sampling ADCs. It shares architectural similarities with other members like the ADS7864Y/2K but differs in packaging and reel configuration. The series is designed for applications demanding high channel count and synchronized conversion without external multiplexing delays.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7864Y/2K is a functional equivalent within the same series, offering identical electrical characteristics but potentially differing in tape and reel packaging specifications. Verify package dimensions and pin assignments before substitution.
