ADS8317IBDGKT

Analog To Digital Converters (ADC) Overview

The ADS8317IBDGKT is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with an analog supply voltage range of 2.7 V to 5.5 V and a digital supply voltage range of 2.7 V to 5.5 V. The device supports a maximum sampling rate of 250 kS/s and features a serial peripheral interface (SPI) compatible with 3-wire communication protocols. Key performance metrics include a signal-to-noise ratio (SNR) of 84.8 dB and a total harmonic distortion-based metric (SINAD) of 89.9 dB. Differential nonlinearity (DNL) is specified at -1/2 LSB, while integral nonlinearity (INL) is +/- 2 LSB. The component 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) Feature Summary

• Supports differential or single-ended input configurations for flexible signal interfacing.
• Integrates a track-and-hold amplifier to maintain signal integrity during conversion cycles.
• Features low power consumption suitable for battery-operated applications.
• Compatible with standard SPI interfaces for straightforward digital connectivity.

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation requiring high resolution and low power.
• Industrial process control systems utilizing isolated data acquisition.
• Battery-powered measurement devices needing extended operational life.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix DGKT corresponds to the VSSOP-8 package and tape-and-reel shipping configuration when sourcing. Confirm that the IB designation indicates the industrial temperature grade (-40°C to +85°C). Ensure compatibility with external reference voltage requirements as the device does not integrate an internal reference. Check for moisture sensitivity level compliance if storage conditions exceed specified limits prior to assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of 16-bit resolution and moderate speed (250 kS/s) is required. It is appropriate for designs where power efficiency is critical but higher speeds found in the ADS8319 series are unnecessary. Consider the VSSOP-8 footprint constraints against available PCB space. Verify that the system can accommodate the need for an external voltage reference to achieve optimal accuracy specifications.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments microPOWER ADC family, designed for precision applications. It shares architectural similarities with other SAR ADCs in the lineup but is distinguished by its specific 250 kS/s throughput and dual supply voltage flexibility. The device serves as a bridge between low-power sensor interfaces and high-resolution data processing units in embedded systems.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8317IDGKT is the commercial grade variant offering identical electrical specifications but with a limited operating temperature range of 0°C to +70°C. Other members of the ADS8317 series may offer different packaging options or slight variations in pinout, requiring schematic review before substitution.
