ADS7823E/2K5

Analog To Digital Converters (ADC) Overview

The ADS7823E/2K5 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-channel input and operates with an I2C serial interface at sampling rates up to 50 kS/s. The device supports differential or single-ended inputs and functions within an analog supply voltage range of 2.7 V to 5.25 V, while the digital supply requires 4.75 V to 5.25 V. It is housed in an 8-pin VSSOP package and is rated for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed SAR ADC architecture optimized for low power consumption
• Supports flexible I2C serial communication interface for simplified system integration
• Accepts both differential and single-ended analog input configurations

Analog To Digital Converters (ADC) Applications

• Portable battery-powered instrumentation systems
• Industrial process control data acquisition
• Medical equipment signal conditioning

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'E/2K5' against official manufacturer documentation to confirm the reel quantity and tape specifications. Ensure that the required digital supply voltage range aligns with your system design, as it differs from the analog supply requirements. Confirm RoHS compliance status through current datasheets before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is sufficient for the application. Consider the I2C interface compatibility with the host microcontroller. Evaluate the power dissipation requirements against the thermal constraints of the VSSOP-8 package. Verify that the input signal range matches the available supply voltages.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS782x family of micro-power ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS7822 and ADS7828 but differs in channel count and interface type. The E/2K5 designation indicates a specific packaging and reel configuration within the broader product line.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7822EC/2K5 offers similar performance but utilizes a 3-wire interface instead of I2C. The ADS7828E/2K5 provides eight channels and I2C support but requires different supply voltage handling. Verify pinout compatibility and software driver adjustments when substituting these alternatives.
