ADS8321EB/2K5

Analog To Digital Converters (ADC) Overview

The ADS8321EB/2K5 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 supports single-channel input with differential, pseudo-differential, or single-ended configurations. The device operates on a 4.75 V to 5.25 V supply for both analog and digital domains, consuming 5.5 mW of power at a sampling rate of 100 kS/s. Key performance metrics include an SNR of 87 dB, DNL of +/- 2 LSB, and INL of +/- 0.012% FSR. It utilizes a 3-wire SPI interface and is housed in a VSSOP-8 package, operating within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'EB/2K5' against the manufacturer's current datasheet to confirm packaging details such as reel size or tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your region. 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 single-channel, 16-bit resolution is required with moderate speed up to 100 kS/s. It is appropriate for designs needing low power consumption while maintaining high accuracy. Consider the external reference requirement and the VSSOP-8 package constraints during PCB layout. Verify that the 5V supply voltage aligns with the system power architecture.

Analog To Digital Converters (ADC) Part Context

The ADS8321 belongs to the family of high-speed, micro-power sampling ADCs from Texas Instruments. It is designed for applications requiring precise data conversion with minimal power usage.
