ADS7823E/250

Analog To Digital Converters (ADC) Overview

The ADS7823E/250 is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single-ended input channel and communicates via an I2C serial interface. The device supports sampling rates up to 50 kS/s with a signal-to-noise ratio of 72 dB. It operates on 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 linearity specifications include a differential nonlinearity (DNL) of -1/3 LSB and integral nonlinearity (INL) of +/- 2 LSB. Power consumption is rated at 1.2 mW, with a maximum power dissipation of 5 mW. It functions within a temperature range of -40°C to +85°C and is housed in a VSSOP-8 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '250' against the manufacturer's official datasheet to confirm packaging configuration, such as reel or cut tape specifications. Ensure that the required operating voltage levels align with the specified analog and digital supply ranges before integration into the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is sufficient for the application. The I2C interface reduces pin count compared to parallel ADCs. Consider the external reference requirement if higher precision than internal references allows. Verify that the 50 kS/s sampling rate meets the bandwidth needs of the input signals.
