ADS7818EB/2K5

Analog To Digital Converters (ADC) Overview

The ADS7818EB/2K5 is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 500 kS/s and utilizes an SPI-compatible serial interface. The device requires both analog and digital power supplies within the range of 4.75 V to 5.25 V. It features differential input configuration and includes an internal voltage reference. Key performance metrics include a signal-to-noise ratio of 72 dB, differential nonlinearity of +/- 1 LSB, and integral nonlinearity of +/- 1 LSB. Power consumption is specified at 11 mW under typical operating conditions.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix EB/2K5 against the manufacturer's current datasheet to confirm package type and reel quantity specifications. Ensure that the required supply voltages match the system design constraints before integration. Check for any recent product change notifications regarding manufacturing site or material composition updates.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed ADC with an internal reference is required. The differential input option is suitable for noisy environments compared to single-ended alternatives. Consider the 5 V supply requirement if lower voltage operation is necessary, as other family members may support wider voltage ranges.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7818 series of high-speed, low-power SAR ADCs from Texas Instruments. The 'E' designation typically indicates an extended temperature range, while 'B' often refers to the specific package variant, such as VSSOP-8. The '/2K5' suffix denotes the standard tape and reel packaging quantity of 2500 units for automated assembly.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7818EVM evaluation module is available for testing. Direct pin-to-pin replacements within the same family should be verified for interface compatibility and power supply requirements. Consult the official cross-reference guide for alternative packages or updated revisions.
