ADS7835EB/2K5

Analog To Digital Converters (ADC) Overview

The ADS7835EB/2K5 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input and an SPI-compatible serial interface with a sampling rate of 500 kS/s. The device operates on a single 4.75 V to 5.25 V supply for both analog and digital domains, consuming 17.5 mW of power. Key performance metrics include a signal-to-noise ratio of 72 dB, differential nonlinearity of ±1 LSB, and integral nonlinearity of ±1 LSB. It is housed in an 8-pin VSSOP package measuring 3 mm x 3 mm x 0.97 mm.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' or '/2K5' against the manufacturer's current datasheet to confirm RoHS compliance and tape-and-reel packaging specifications. Ensure the ordering part number matches the exact package variant required for your PCB footprint, as suffixes may indicate minor manufacturing updates without functional changes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between moderate speed (500 kS/s) and low power dissipation is required. It is suitable for designs constrained by a single 5V supply rail. Compare against the ADS7836 if higher resolution or additional channels are needed, or consider the ADS7822 for lower power requirements at reduced sampling rates.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS783x family of 12-bit SAR ADCs from Texas Instruments. The family is characterized by its ability to operate from a single supply voltage while maintaining high accuracy. The ADS7835 specifically targets applications needing faster conversion speeds compared to other members like the ADS7822, fitting into the mid-range performance tier of the series.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes include the ADS7836E/250 for similar performance with potential pin compatibility variations. Verify electrical characteristics and package dimensions before substitution.
