ADS8321EB/2K5G4

Analog To Digital Converters (ADC) Overview

The ADS8321EB/2K5G4 is a 16-bit, high-speed, micro-power sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a successive approximation register (SAR) architecture and operates on a single 5V supply, with analog and digital power voltages ranging from 4.75 V to 5.25 V. The device supports a maximum sampling rate of 100 kS/s and offers flexible input configurations including differential, pseudo-differential, and single-ended modes. It utilizes a 3-wire serial interface compatible with standard SPI protocols. Key performance metrics include an SNR of 87 dB, DNL of +/- 2 LSB, and INL of +/- 0.012% FSR. Power consumption is specified at 5.5 mW typical and 8.5 mW maximum. It is housed in an 8-VSSOP package and operates within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'EB/2K5G4' against the manufacturer's current datasheet to confirm packaging details, such as reel quantity or tape-and-reel specifications, as these can vary. Ensure the component meets RoHS compliance requirements if mandated by your project standards. Cross-reference the ordering part number with authorized distributors to confirm availability and authenticity before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of 16-bit resolution and moderate speed (100 kS/s) is required alongside strict power constraints. It is suitable for designs needing a single 5V supply without external negative voltage generation. Consider the external reference requirement and the 8-VSSOP package size during PCB layout planning. Verify that the input signal range matches the device capabilities.

Analog To Digital Converters (ADC) Part Context

The ADS8321 belongs to Texas Instruments' family of high-speed, micro-power sampling ADCs. This series is designed for applications where power efficiency and accuracy are critical. The EB/2K5G4 variant specifically denotes the commercial grade version in a tape-and-reel packaging format, distinguishing it from bulk or evaluation module versions within the same functional family.

Analog To Digital Converters (ADC) Replacement Considerations
