ADS8515IBDBR

Analog To Digital Converters (ADC) Overview

The ADS8515IBDBR is a 16-bit, 250-kSPS CMOS analog-to-digital converter manufactured by Texas Instruments. It utilizes a successive approximation register (SAR) architecture and features a single-ended input configuration with an integrated internal oscillator. The device operates on a single 5-V supply, accepting analog input voltages from 0 V to VREF. Key electrical specifications include a signal-to-noise ratio (SNR) of 93 dB, a differential nonlinearity (DNL) of ±1 LSB, and an integral nonlinearity (INL) of ±1.5 LSB. It is housed in a 28-pin SSOP package and supports operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed 16-bit SAR ADC core with an internal clock oscillator for simplified system design.
• Provides low-power operation suitable for battery-powered or energy-constrained applications.
• Features a flexible reference input that accommodates both external and internal voltage references.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring precise analog signal acquisition.
• Portable medical instrumentation such as patient monitors and diagnostic devices.
• Data acquisition modules in automated testing equipment.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the exact pinout and thermal characteristics required for the target PCB layout. Cross-reference the datasheet revision date to guarantee access to the most current electrical parameters and application notes.

Analog To Digital Converters (ADC) Selection Notes

Select this component for designs requiring a balance between resolution and sampling speed without external clock circuitry. Compare against the ADS8505 if a parallel interface is preferred over the serial SPI connection used here. Evaluate power consumption requirements against the typical 155 mW dissipation at maximum sampling rates. Consider the SSOP-28 footprint constraints during mechanical design phases.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS85xx family of 16-bit sampling ADCs from Texas Instruments. It shares architectural similarities with the ADS8505 but differs in its serial communication interface. The IBDBR designation specifies the industrial temperature grade, SSOP-28 package, and tape-and-reel delivery method. It serves as a direct replacement for older Burr-Brown series converters in legacy designs.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8505IBDBR offers identical performance metrics but utilizes a parallel interface instead of SPI. Designers must verify logic level compatibility and pin assignment differences before swapping these parts. No other direct pin-compatible substitutes are documented in public sources.
