ADS8517IBDWR

Analog To Digital Converters (ADC) Overview

The ADS8517IBDWR is a low-power, single-supply, 16-bit sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a successive approximation register (SAR) architecture with an integrated sample-and-hold circuit and internal reference. The device supports a minimum sampling rate of 200 kSPS and operates over an industrial temperature range of -40°C to +85°C. It features a flexible data interface compatible with both parallel and serial (SPI) modes. Electrical specifications include a maximum integral nonlinearity (INL) of ±1.5 LSB and a signal-to-noise ratio (SNR) of 89 dB at the high-grade IB variant.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with 200-kSPS throughput rate
• Integrated 2.5-V internal reference or external reference capability
• Flexible parallel and SPI-compatible serial output interfaces
• Single 5-V analog supply with 1.65-V to 5.5-V digital interface supply

Analog To Digital Converters (ADC) Applications

• Portable test equipment
• USB data acquisition modules
• Medical equipment
• Industrial process control
• Digital signal processing systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific grade suffix 'IB' for ±1.5 LSB INL performance against standard 'I' grade specifications. Confirm the 'DWR' suffix indicates the SOIC-28 package in tape and reel format with a quantity of 1000 units. Ensure compatibility with the required input voltage ranges and power-down mode requirements for the target application design.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS8517IBDWR when a 16-bit SAR ADC with simultaneous parallel and serial interface options is required. The device supports input ranges of ±10 V, 4 V, and 5 V without external precision resistors. Consider the power dissipation of 60 mW max at 200 kSPS and the 50-μW max power-down mode for battery-operated constraints.

Analog To Digital Converters (ADC) Part Context

The ADS8517 belongs to the ADS8517 family of 16-bit sampling ADCs. It is pin-compatible with the 16-bit ADS7807 and ADS8507, as well as the 12-bit ADS7806 and ADS8506. This compatibility allows for direct upgrades or pin-swaps in existing designs requiring different resolution or speed characteristics within the same package footprint.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements include the ADS7807, ADS8507, ADS7806, and ADS8506. Verify that the substitute part meets the specific INL, SNR, and sampling rate requirements of the original design before implementation.
