ADS8515IBDBRG4

Analog To Digital Converters (ADC) Overview

The ADS8515IBDBRG4 is a 16-bit, 250-kSPS CMOS analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a successive approximation register (SAR) architecture with a single-ended input and SPI serial interface. The device operates on an analog supply of 4.75 V to 5.25 V and a digital supply of 1.65 V to 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) of 93 dB, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±1.5 LSB. It is housed in an SSOP-28 package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated internal oscillator eliminates the need for external clocking components.
• Daisy-chainable architecture allows multiple devices to be connected in series for system expansion.
• Supports both external and internal reference configurations for flexible voltage referencing.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition.
• Medical instrumentation such as ultrasound and patient monitoring equipment.
• Test and measurement instruments including oscilloscopes and analyzers.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RG4' against the manufacturer's current documentation to confirm RoHS compliance status and lead time requirements. Ensure the SSOP-28 package availability aligns with production schedules. Cross-reference the part number with official distributors to confirm authenticity and avoid counterfeit components during sourcing.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution at 250 kSPS is required with a serial interface. It is suitable for applications needing daisy-chaining capabilities and integrated oscillators. Consider the dual-supply requirement (analog vs. digital) and the specific SNR and linearity specifications relative to system noise floors before finalizing the design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS851x family of high-speed, high-resolution ADCs from Texas Instruments. It shares architectural similarities with the ADS8519 but differs in specific interface or pinout configurations. The family is designed for demanding applications where precision and speed are critical, offering a balance between performance and power consumption in a compact SSOP package.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8519IBDB is a functional substitute within the same family, offering similar 16-bit resolution and sampling rates. Verify pin compatibility and interface specifics before substitution. Other family members like the ADS8515 may serve as alternatives if interface differences are acceptable.
