ADS7823EB/250

Analog To Digital Converters (ADC) Overview

The ADS7823EB/250 is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single-ended input and an I2C serial interface, supporting sampling rates up to 50 kS/s. The device operates with an analog supply voltage ranging from 2.7 V to 5.25 V and a digital supply voltage between 4.75 V and 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) of 72 dB, differential nonlinearity (DNL) of -1/3 LSB, and integral nonlinearity (INL) of +/- 1 LSB. Power consumption is specified at 1.2 mW typical and 5 mW maximum. It is housed in an 8-pin VSSOP package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'EB/250' against the manufacturer's official datasheet to confirm packaging details and reel specifications. Ensure compatibility with I2C bus voltage levels and check for moisture sensitivity classification requirements during storage and handling. Confirm that the external reference voltage source meets the stability requirements for optimal linearity performance.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is required with I2C communication. Consider the 50 kS/s sampling rate limit and the specific supply voltage constraints. Evaluate the need for an external reference voltage versus internal options if available in other variants. Ensure the VSSOP-8 package fits the PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7823 series of low-power, 12-bit ADCs. It shares architectural similarities with other members of the family but differs in packaging and specific electrical characteristics defined by the EB/250 designation. It serves as a cost-effective solution for applications needing moderate speed and resolution without complex parallel interfaces.

Analog To Digital Converters (ADC) Replacement Considerations

Consult the Texas Instruments product selection guide for direct pin-compatible or functionally equivalent alternatives within the ADS782x family. Verify that any substitute maintains the same I2C interface protocol and voltage supply requirements.
