ADS8517IPWR

Analog To Digital Converters (ADC) Overview

The ADS8517IPWR is a 16-bit, 200-kSPS sampling analog-to-digital converter (ADC) from Texas Instruments. It utilizes a successive approximation register (SAR) architecture with an internal 2.5-V reference and sample-and-hold circuit. The device supports single-ended inputs with configurable ranges including ±10 V, 4 V, and 5 V, featuring high-impedance inputs that tolerate voltages up to ±25 V without damage. It offers flexible data interfaces via parallel or SPI-compatible serial outputs. Powered by a single 4.5-V to 5.5-V analog supply and a 1.65-V to 5.5-V digital interface supply, it operates within the industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'PWR' suffix indicates the TSSOP-28 package and tape-and-reel shipping quantity of 2000 units. Confirm the 'I' grade specifies ±3 LSB max INL and ±3 LSB max DNL performance. Ensure the order matches the specific temperature range and electrical characteristics defined for the ADS8517I variant in the official datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power consumption and high accuracy in a single-supply environment. The internal reference simplifies design by eliminating external precision resistors. Consider the parallel interface for high-speed data transfer needs or the serial interface for pin-count reduction. Verify that the input voltage requirements align with the supported ±10 V, 4 V, or 5 V ranges.

Analog To Digital Converters (ADC) Part Context

The ADS8517 belongs to the ADS8517 family of low-power, 16-bit SAR ADCs. It is pin-compatible with the 16-bit ADS7807 and ADS8507, as well as the 12-bit ADS7806 and ADS8506. This compatibility facilitates direct upgrades or replacements in existing designs utilizing these predecessor devices.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible substitutes include the ADS8507, ADS7807, ADS8506, and ADS7806. When replacing, verify that the required resolution and input voltage ranges match the target application specifications.
