ADS7817E/2K5G4

Analog To Digital Converters (ADC) Overview

The ADS7817E/2K5G4 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a differential input architecture and operates with a sampling rate of 200 kS/s. The device requires external voltage references and supports serial communication via a 3-wire SPI interface. Power supply voltages for both analog and digital sections range from 4.75 V to 5.25 V. It is housed in an SOIC-8 surface-mount package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Differential input configuration for improved noise rejection
• Low power consumption suitable for battery-operated systems
• Flexible serial interface compatible with standard microcontrollers

Analog To Digital Converters (ADC) Applications

• Portable instrumentation requiring low power ADCs
• Industrial process control data acquisition
• Medical equipment signal conditioning

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the tape and reel quantity matches the required production volume. Ensure the SOIC-8 package dimensions align with the target PCB footprint design constraints.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-resolution conversion is needed with minimal power draw. The differential input is critical for applications involving noisy environments or small signal levels. Verify that the system can provide the necessary external reference voltage, as the device does not include an internal one.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7817 family of micro-power sampling ADCs. It shares architectural similarities with the ADS7816 but offers optimized performance characteristics for specific industrial and portable applications. The E/2K5G4 designation specifies the operating temperature grade, reel packaging format, and environmental compliance attributes defined by the manufacturer.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7817E/250 is a documented alternative variant within the same product family. Verify pin compatibility and electrical parameter equivalence before substitution. Other members of the ADS78xx series may require circuit modifications due to differing interface protocols or power requirements.
