ADS8321E/250

Analog To Digital Converters (ADC) Overview

The ADS8321E/250 is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It supports a sampling rate of up to 100 kS/s and operates on a single supply voltage ranging from 2.7 V to 5.25 V for both analog and digital domains. The device features a serial interface compatible with standard SPI protocols and accepts differential, pseudo-differential, or single-ended input signals. Key performance metrics include a signal-to-noise ratio of 90 dB and a power consumption of approximately 5.5 mW at full speed. It is housed in an 8-pin VSSOP package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'E/250' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage levels and interface timing requirements before integration. Check for RoHS compliance status as indicated in official documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 16-bit resolution is required with a maximum sampling rate of 100 kS/s. It is appropriate for designs needing a wide supply voltage range from 2.7 V to 5.25 V. Consider the VSSOP-8 package size constraints and the need for an external voltage reference if higher precision than internal options allows.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS832x family of micro-power sampling ADCs from Texas Instruments. It shares architectural similarities with the ADS8320 but offers distinct input flexibility and performance characteristics tailored for general-purpose high-resolution data acquisition tasks in compact form factors.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8320 is a related device within the same family. Verify pinout compatibility and functional differences such as input configuration support before substitution. Consult the official interchangeability guidelines provided by Texas Instruments.
