ADS7864Y/250G4

Analog To Digital Converters (ADC) Overview

The ADS7864Y/250G4 is a dual 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features six differential analog inputs and simultaneous sampling capabilities with an internal reference. The device operates on a single 5V supply, supporting both analog and digital voltages between 4.75 V and 5.25 V. It delivers a sampling rate of 500 kS/s per channel via a parallel interface. Key performance metrics include a signal-to-noise ratio of 71 dB, differential nonlinearity of +/- 0.6 LSB, and integral nonlinearity of 2 LSB. Power consumption is rated at 50 mW, and it functions within a temperature range of -40°C to +85°C in a TQFP-48 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS adherence when sourcing. Confirm the specific tape-and-reel quantity matches production requirements. Ensure ESD protection protocols are followed during handling due to moisture sensitivity classification. Cross-reference the distributor part number against the manufacturer datasheet to validate authenticity and revision level before integration into supply chains.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of multiple channels is critical rather than sequential scanning. The 12-bit resolution balances precision with speed for general-purpose applications. Consider the parallel interface complexity against available microcontroller GPIO resources. Evaluate the power dissipation limits relative to thermal management capabilities in the final enclosure design.

Analog To Digital Converters (ADC) Part Context

This model belongs to the ADS7864 series of high-speed ADCs from Texas Instruments. It shares architectural similarities with other devices in the family but is distinguished by its specific pinout, sampling rate, and channel configuration. The G4 suffix denotes environmental compliance modifications compared to earlier iterations of the same functional part.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7864Y/250 serves as the direct functional equivalent without the environmental suffix. Verify pin compatibility and electrical specifications match exactly before substitution.
