ADS8326IDRBT

Analog To Digital Converters (ADC) Overview

The ADS8326IDRBT is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single pseudo-differential or single-ended input channel and operates on a supply voltage range of 2.7 V to 5.5 V for both analog and digital domains. The device supports a maximum sampling rate of 250 kS/s via a serial peripheral interface (SPI). Key performance metrics include a signal-to-noise ratio (SNR) of 91 dB, an integral nonlinearity (INL) of ±3 LSB, and a differential nonlinearity (DNL) of -1/2 LSB. Power consumption is rated at 10 mW under typical conditions. It is housed in an 8-lead SON package with dimensions of 3 mm x 3 mm.

Analog To Digital Converters (ADC) Feature Summary

• Ultra-low power consumption enables extended battery life in portable applications, with average power dropping below 0.2 mW at lower data rates such as 10 kHz.
• High precision conversion characteristics ensure excellent linearity and minimal noise, making it suitable for high-fidelity signal acquisition tasks.
• Flexible input configuration supports both pseudo-differential and single-ended modes, accommodating various sensor interface requirements.

Analog To Digital Converters (ADC) Applications

• Portable and battery-powered measurement systems requiring low energy usage
• Remote data acquisition modules for industrial monitoring
• Isolated data acquisition systems utilizing digital isolation barriers

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDRBT corresponds to the SON-8 package and tape-and-reel shipping format when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the external reference voltage source matches the required input range specifications for optimal accuracy.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution is necessary alongside low power constraints. Compare against the ADS8317 if bipolar input ranges are required instead of unipolar. Consider pin-compatible alternatives like the ADS7816 or ADS7822 only if legacy board compatibility is mandatory without upgrading resolution.

Analog To Digital Converters (ADC) Part Context

This part belongs to the microPOWER family of ADCs from Texas Instruments. It serves as a 16-bit upgrade to earlier 12-bit models such as the ADS7816 and ADS7822. The device maintains pin compatibility with these predecessors while offering improved resolution and performance metrics within a compact surface-mount footprint.

Analog To Digital Converters (ADC) Replacement Considerations

ADS8326IBDGKT: Alternative VSSOP-8 package version with identical electrical specifications. ADS8326IDGKR: MSOP-8 package variant offering the same functional performance in a different physical form factor.
