ADS8339IDGSR

Analog To Digital Converters (ADC) Overview

The ADS8339IDGSR is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a maximum sampling rate of 250 kSPS and features a single-ended input configuration. The device utilizes an external reference voltage ranging from 2.25 V to 5.5 V, while the analog supply voltage ranges from 4.5 V to 5.5 V and the digital supply voltage ranges from 2.375 V to 5.5 V. Key performance metrics include a signal-to-noise ratio (SNR) of 93.6 dB and a signal-to-noise and distortion ratio (SINAD) of 93.8 dB. It integrates a built-in oscillator and supports SPI communication. The component is housed in a 10-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 against official Texas Instruments documentation to confirm package type and temperature grade. Ensure the external reference voltage matches the specified operational range. Confirm moisture sensitivity level handling requirements during assembly. Cross-reference the ordering part number with current datasheets to validate availability status.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 250 kSPS throughput are required for single-ended signals. Consider the external reference requirement if internal references are not available in the target design. Evaluate the power consumption profile relative to the desired sampling rate. Ensure the PCB layout accommodates the 10-VSSOP package dimensions and thermal constraints.
