ADS7828EB/2K5

Analog To Digital Converters (ADC) Overview

The ADS7828EB/2K5 is a 12-bit, 8-channel successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features an I2C serial interface and operates with a sampling rate of 50 kSPS. The device supports pseudo-differential or single-ended inputs and includes an internal reference. Power supply voltages for both analog and digital sections range from 2.7 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 72 dB, differential nonlinearity of -1/2 LSB, and integral nonlinearity of +/- 1 LSB. It consumes 675 uW during operation and 5 mW power dissipation, functioning within a temperature range of -40°C to +85°C in a 16-TSSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel multiplexer with sample-and-hold functionality for efficient multi-point data acquisition.
• Supports standard and fast-mode I2C communication protocols for simplified system integration.
• Offers flexible reference configuration options with both internal and external voltage reference capabilities.

Analog To Digital Converters (ADC) Applications

• Battery-powered portable instrumentation systems requiring low power consumption.
• Industrial process control loops involving multiple sensor inputs.
• Data acquisition modules in embedded monitoring applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'EB/2K5' against the manufacturer's current datasheet to confirm packaging type and reel specifications. Ensure compatibility with I2C bus voltage levels and check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-channel input count is required alongside a serial interface to minimize microcontroller GPIO usage. Consider the 50 kSPS sampling limit and 12-bit resolution for bandwidth requirements. Evaluate the need for the internal reference versus an external precision reference based on system accuracy needs and board space constraints.

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 the ADS7823 and ADS7824 but provides eight channels instead of four. The EB/2K5 designation indicates a specific tape and reel packaging variant suitable for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7828E is the standard commercial grade equivalent without the specific EB/2K5 packaging suffix. ADS7828-Q1 is available for automotive applications requiring AEC-Q100 qualification. Verify pin compatibility and software register maps when substituting with other members of the ADS782x series.
