ADS8512IBDW

Analog To Digital Converters (ADC) Overview

The ADS8512IBDW is a 16-bit, low-power sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single-ended input configuration and utilizes an SPI serial interface for data communication. The device operates on a single 5-V supply with analog and digital voltage ranges of 4.75 V to 5.25 V. It supports a maximum sampling rate of 40 kSPS and includes an internal oscillator. Key performance metrics include a signal-to-noise ratio (SNR) of 89 dB and a power dissipation of 32.5 mW. The component is housed in a 16-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 16-bit successive approximation register (SAR) ADC core with a single-ended input structure.
• Incorporates an internal oscillator to simplify system clocking requirements.
• Supports standard SPI serial interface for digital data output and control.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IBDW' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure that the required operating temperature range aligns with the specified industrial limits. Confirm that the system power supply strictly adheres to the 4.75 V to 5.25 V specification to maintain accuracy. Check for moisture sensitivity levels if storage conditions are not controlled.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution is necessary for precision measurements at speeds up to 40 kSPS. It is suitable for designs constrained by a single 5-V supply rail. Consider alternatives if differential inputs or higher sampling rates are required. Evaluate the trade-off between the integrated oscillator and external clock jitter requirements for your specific application noise floor.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS85xx series of low-power sampling ADCs from Texas Instruments.
