ADS8339IDGST

Analog To Digital Converters (ADC) Overview

The ADS8339IDGST is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input and operates with an analog supply voltage range of 4.5 V to 5.5 V and a digital supply voltage range of 2.375 V to 5.5 V. The device supports a sampling rate of 250 kSPS and utilizes an SPI-compatible serial interface. 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 is housed in a 10-VSSOP package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a SAR ADC architecture with a built-in sample-and-hold circuit for efficient data conversion.
• Supports daisy-chainable operation via the SPI interface to facilitate multi-device systems.
• Includes a busy indicator pin to simplify synchronization with digital host processors.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring low power consumption.
• Battery-powered measurement devices utilizing external reference voltages.
• Industrial process control applications needing high-resolution single-channel acquisition.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IDGST' corresponds to the MSOP-10/VSSOP-10 package variant and industrial temperature grade (-40°C to +85°C). Confirm that the external reference voltage requirements align with the specified 2.25 V to 5.5 V range. Ensure compatibility with the 2.375 V to 5.5 V digital logic levels before integration into the design.

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. It is suitable for designs prioritizing low power dissipation, which scales directly with speed. Consider the need for an external voltage reference, as the device does not integrate one internally. Verify that the system can accommodate the 10-pin surface-mount packaging constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the microPOWER™ series of precision ADCs from Texas Instruments. It is functionally similar to the ADS8319 but offers higher sampling rates. The 'I' designation indicates industrial temperature rating, while 'DGST' specifies the tape and reel packaging format for the 10-VSSOP body.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8339IDGSR is a compatible alternative offering identical electrical specifications and functionality, differing only in the bulk tape and reel packaging quantity rather than the component itself.
