ADS8317IDRBR Equivalent & Substitute Parts

Part Overview

The ADS8317IDRBR is a 16-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for data acquisition applications requiring single-channel differential input conversion. This microPOWER™ series component operates as a successive approximation register (SAR) ADC with external reference capability and SPI digital interface. The part is currently in active production status with full RoHS3 compliance and REACH unaffected classification. Substitute parts are identified when equivalent electrical performance, package compatibility, and supply voltage specifications align with the original component requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ADS8317IDRBR are identified based on strict parametric equivalence within the ADS8317 base product family. The substitution criteria are limited to the following parameters:

• 16-bit resolution
• 250k samples per second sampling rate
• Single differential input channel
• SPI digital interface
• SAR architecture with external reference
• Dual supply voltage support (2.7V ~ 3.6V and 5V for both analog and digital rails)
• Operating temperature range of -40°C ~ 85°C
• 8-VDFN exposed pad package (8-SON 3x3 form factor)
• Surface mount configuration
• Active product status
• RoHS3 compliance and REACH unaffected status

The identified substitutes differ only in packaging designation (tape and reel suffix variations), which does not affect electrical performance or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ADS8317IDRBR, ADS8317IBDRBR, and ADS8317IBDRBT—are functionally equivalent for data acquisition applications requiring 16-bit single-channel differential ADC conversion. Selection between these parts is based on supply chain availability and packaging designation rather than electrical performance differences.

All substitute parts maintain active product status with Texas Instruments, ensuring continued manufacturing support and availability. RoHS3 compliance and REACH unaffected status are consistent across all variants, meeting regulatory requirements for industrial and commercial applications.

Moisture sensitivity level (MSL 2, 1 Year) is identical across all parts, establishing equivalent handling and storage requirements during component procurement and assembly operations.

Frequently Asked Questions (FAQ)

Q: Are ADS8317IBDRBR and ADS8317IBDRBT direct substitutes for ADS8317IDRBR?

A: Yes. All three parts share identical electrical specifications, including 16-bit resolution, 250k samples per second sampling rate, single differential input, SPI interface, and dual supply voltage support (2.7V ~ 3.6V and 5V). The suffix variations indicate packaging designation only and do not affect functional compatibility or performance.

Q: What is the difference between the part number suffixes?

A: The suffix variations (IDRBR, IBDRBR, IBDRBT) denote different tape and reel packaging configurations used during component distribution. These designations do not alter the integrated circuit's electrical characteristics or pin configuration.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All three parts use the identical 8-VDFN exposed pad package (8-SON 3x3 form factor) with surface mount configuration. PCB footprints, solder pad layouts, and thermal management characteristics are equivalent across all variants.

Q: Are there any supply voltage compatibility considerations?

A: No. All parts support identical analog and digital supply voltage ranges (2.7V ~ 3.6V and 5V), allowing operation in both low-power and standard voltage applications without design modification.

Q: What is the operating temperature range for these components?

A: All parts operate across -40°C to 85°C, suitable for industrial and commercial temperature environments.

Q: Are there any compliance or regulatory differences between these parts?

A: No. All three parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 2, 1 Year), ensuring equivalent regulatory and environmental qualification.
