ADS7835EB/250G4

Analog To Digital Converters (ADC) Overview

The ADS7835EB/250G4 is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with an SPI-compatible serial interface and supports sampling rates up to 500 kS/s. The device functions on a single 5-V supply, accepting analog input voltages from ground to VCC. Key electrical specifications include a signal-to-noise ratio of 72 dB, differential nonlinearity of +/- 1 LSB, and integral nonlinearity of +/- 1 LSB. Power consumption is rated at 17.5 mW during operation, with a maximum power dissipation of 30 mW. It features an internal reference and is housed in an 8-pin VSSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix '250' corresponds to the required reel quantity and packaging configuration before finalizing procurement. Confirm that the VSSOP-8 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the intended deployment scenario.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is sufficient for the application. Consider the 500 kS/s sampling rate against the Nyquist requirement of the input signal bandwidth. Evaluate the need for an internal reference versus an external precision reference based on system accuracy requirements and cost constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7835 family of low-power, high-speed ADCs. It shares architectural similarities with other members like the ADS7822 and ADS7830 but offers specific resolution and speed characteristics tailored for general-purpose data acquisition tasks within the Texas Instruments portfolio.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative SAR ADCs from the same manufacturer only if datasheet parameters match exactly.
