ADS8320E/2K5

Analog To Digital Converters (ADC) Overview

The ADS8320E/2K5 is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.25 V for both analog and digital domains. The device supports a maximum sampling rate of 100 kS/s with a serial interface compatible with standard SPI protocols. Key performance metrics include a signal-to-noise ratio (SNR) of 90 dB, a signal-to-noise and distortion ratio (SINAD) of 84 dB, differential nonlinearity (DNL) of ±2 LSB, and integral nonlinearity (INL) of ±0.018% FSR. Power consumption is specified at 4.5 mW, with a maximum power dissipation of 8.5 mW. It is housed in an 8-lead VSSOP package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging format. Confirm that the component meets RoHS compliance requirements for your region. Check humidity sensitivity levels and recommended reflow soldering profiles prior to assembly. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single channel with 16-bit resolution is required alongside strict power constraints. Compare SNR and INL specifications against system noise floors to ensure adequate dynamic range. Verify that the external reference voltage matches the desired input span. Consider the VSSOP-8 package size relative to available PCB real estate.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8320 family of high-speed, micropower ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS8321 and ADS8325 but differs in channel count and specific pinout configurations. The E/2K5 designation indicates a specific tape-and-reel packaging variant intended for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADS8321 and ADS8325, though pinouts and channel counts may differ. Cross-family replacements such as the ADS8341 offer multiple channels but require interface adjustments. Always verify electrical compatibility and mechanical footprint before swapping components.
