ADS7828EB/250

Analog To Digital Converters (ADC) Overview

The ADS7828EB/250 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features an internal multiplexer supporting eight single-ended or four pseudo-differential input channels. The device operates with a sampling rate of 50 kSPS and communicates via an I2C serial interface. It supports analog and digital supply voltages ranging from 2.7 V to 5.25 V, enabling flexible power integration. Key performance metrics include a signal-to-noise ratio of 72 dB, differential nonlinearity of -1/2 LSB, and integral nonlinearity of +/- 1 LSB. Power consumption is specified at 675 uW during operation and 5 mW peak dissipation. The component is housed in a 16-pin TSSOP 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 current datasheet to confirm packaging details such as reel size or tape specifications. Ensure the ordering part number matches the required temperature grade and pin configuration. Cross-reference with official distributor catalogs to validate availability status and compliance certifications like RoHS before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate resolution and low power consumption is required for multi-channel sensing. The integrated I2C interface reduces microcontroller pin usage compared to parallel ADCs. Consider the 50 kSPS limit for application bandwidth requirements. Verify that the input voltage range aligns with the available reference voltage options, either internal or external, to ensure accurate signal conversion across the desired dynamic range.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS782x family of microPower 12-bit ADCs from Texas Instruments. It shares architectural similarities with models like the ADS7823 and ADS7824 but offers distinct channel counts and interface configurations. The EB/250 designation indicates a specific commercial-grade variant within the broader series, designed for cost-sensitive applications requiring reliable analog-to-digital conversion in compact form factors.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADS7828E/2K5, which shares identical electrical characteristics and pinout. Other compatible alternatives may include the ADS7823 or ADS7824 if channel count differences are acceptable. Verify pin compatibility and software register mappings when migrating between these variants to ensure seamless integration without hardware redesign.
