ADS8326IBDGKTG4

Analog To Digital Converters (ADC) Overview

The ADS8326IBDGKTG4 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 kSPS. The device features a pseudo-differential or single-ended input architecture and communicates via a standard SPI interface. Key performance metrics include a signal-to-noise ratio of 91.5 dB, differential nonlinearity of ±1 LSB, and integral nonlinearity of ±2.5 LSB. It consumes 10 mW of power and functions within a temperature range of -40°C to +85°C. The component is housed in an 8-VSSOP package.

• Industrial process control systems utilizing serial communication interfaces
• Medical equipment needing precise analog signal acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and lead-free manufacturing status as per Texas Instruments documentation. Confirm the package type matches the required 8-VSSOP footprint for PCB layout compatibility. Ensure the operating voltage requirements align with the system's 2.7 V to 5.5 V supply rails. Check for any specific moisture sensitivity level handling requirements during assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 16-bit resolution is required with moderate speed capabilities. It is appropriate for designs where power efficiency is critical but higher speeds are not necessary. Consider the external reference requirement if high accuracy is needed, as the device does not integrate an internal reference. Evaluate the thermal performance within the specified industrial temperature range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the microPOWER™ series of data converters from Texas Instruments. It shares architectural similarities with other ADS832x variants but differs in packaging and specific electrical tolerances. The I grade denotes the industrial temperature range operation. The DGKT suffix specifies the tape and reel packaging format for automated assembly.

Analog To Digital Converters (ADC) Replacement Considerations

ADS8326IBDGKT is the non-G4 variant with identical electrical specifications but potentially different packaging or environmental compliance details. ADS8326IDGKR is a related variant with slightly different linearity specifications and potentially discontinued status. Verify pinout compatibility before substitution.
