ADS8326IDGKR

Analog To Digital Converters (ADC) Overview

The ADS8326IDGKR is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with an analog and digital supply voltage range of 2.7 V to 5.5 V and supports sampling rates up to 250 kS/s. The device features a pseudo-differential or single-ended input structure and communicates via a standard SPI interface. Key performance metrics include a signal-to-noise ratio of 91 dB, differential nonlinearity of -1/2 LSB, and integral nonlinearity of +/- 3 LSB. It functions within a temperature range of -40°C to +85°C and is housed in an 8-pin VSSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed SAR ADC architecture for efficient data conversion without requiring external clocking circuitry.
• Supports flexible input configurations through pseudo-differential and single-ended modes to accommodate various sensor types.
• Utilizes a simple serial peripheral interface (SPI) compatible with standard microcontroller communication protocols.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring low power consumption
• Battery-powered data acquisition modules
• Industrial process control sensors

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'KR' indicates tape-and-reel packaging when sourcing components. Confirm that the operating environment remains within the specified -40°C to +85°C industrial temperature range. Ensure the external reference voltage matches the device's input requirements for optimal accuracy. Check for moisture sensitivity level compliance during storage and handling procedures.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of 16-bit resolution and moderate speed is required for single-channel applications. Consider the VSSOP-8 package constraints for PCB layout space. Evaluate the need for an external voltage reference, as the device does not include an internal one. Compare power dissipation specifications against thermal management capabilities in the target enclosure.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS832x family of micro-power ADCs from Texas Instruments. It shares architectural similarities with the ADS8325 but offers higher sampling rates. The IDGKR designation specifies the industrial temperature grade and surface-mount VSSOP-8 packaging format used for compact electronic designs.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8325IDGKR is a related variant within the same family, though it typically operates at lower sampling speeds. Verify pin compatibility and software register settings before substitution. Other members of the ADS832x series may offer different channel counts or power profiles.
