ADS8326IBDGKR

Analog To Digital Converters (ADC) Overview

The ADS8326IBDGKR is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with sampling rates up to 250 kSPS and supports pseudo-differential or single-ended input configurations. The device functions within an analog and digital supply voltage range of 2.7 V to 5.5 V, consuming approximately 10 mW of power. It features an SPI-compatible serial interface and requires an external voltage reference. Key performance metrics include a signal-to-noise ratio of 91 dB, differential nonlinearity of ±1/2 LSB, and integral nonlinearity of ±3 LSB. The component is housed in an 8-lead MSOP package and operates across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed 16-bit SAR ADC core optimized for low-power consumption applications.
• Supports flexible input configurations including pseudo-differential and single-ended modes.
• Utilizes a standard three-wire serial interface compatible with SPI protocols for data output.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring high resolution and low power.
• Battery-powered data acquisition modules.
• Industrial process control signal conditioning.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix DGKR corresponds to the tape-and-reel packaging format when ordering. Confirm that the required external reference voltage matches the device's input specifications. Ensure PCB layout guidelines for the MSOP-8 package are followed to maintain signal integrity at 250 kSPS speeds. Check RoHS compliance status for environmental regulations relevant to the target market.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between 16-bit resolution and moderate speed is required. Compare against the ADS8325 if higher channel counts are needed, or the ADS8320 if lower cost is prioritized over the extended voltage range. Ensure the system can accommodate an external reference source as the device lacks an internal one. Validate that the MSOP-8 footprint fits the mechanical constraints of the design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the microPOWER family of data converters from Texas Instruments. It shares architectural similarities with the ADS8325 and ADS8320 but offers specific pinout and performance characteristics tailored for space-constrained designs. The IB designation indicates the industrial temperature grade variant within the broader ADS8326 product line.

Analog To Digital Converters (ADC) Replacement Considerations

ADS8325IDGKR: Offers similar performance but may differ in pin configuration or channel count. ADS8320IBDGKR: Provides comparable functionality with a slightly different voltage range specification. Verify electrical compatibility and mechanical fit before substitution.
