ADS8325IDRBRG4

Analog To Digital Converters (ADC) Overview

The ADS8325IDRBRG4 is a high-speed, low-power, 16-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a sampling rate of 100 ksps and operates on a single supply voltage ranging from 2.7 V to 5.5 V. The device integrates a fast successive approximation register (SAR) architecture with an internal 2.5 V reference and a track-and-hold amplifier. It communicates via a standard synchronous serial interface compatible with SPI, QSPI, and MICROWIRE protocols. The component is housed in an 8-pin VSSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 16-bit SAR ADC core with a built-in 2.5 V reference for simplified system design.
• Supports flexible digital interfaces including SPI, QSPI, and MICROWIRE modes.
• Features a high-impedance input stage with an integrated track-and-hold circuit.

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation
• Industrial process control systems
• Battery-powered data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RG4' indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the package type matches the required PCB footprint. Ensure the operating temperature range aligns with the target application environment before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between resolution and speed is required for battery-operated devices. The 100 ksps rate suits moderate-speed applications where power consumption must be minimized. Verify that the serial interface timing requirements match the host microcontroller capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS832x family of 16-bit ADCs. It shares architectural similarities with the ADS8325 but differs in packaging and environmental ratings compared to other variants like the IDGKR. The IDRBRG4 designation specifies the tape and reel packaging format suitable for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8325IDRBR is a non-RoHS compliant alternative within the same series. Check datasheet revisions for pin compatibility and electrical parameter equivalence before substituting.
