ADS7250IRTER Equivalent & Substitute Parts

Part Overview

The ADS7250IRTER is a 12-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for data acquisition applications requiring simultaneous sampling of multiple analog inputs. This SAR (Successive Approximation Register) architecture device features 2 pseudo-differential inputs with 2 independent SAR converters and SPI digital interface. The part is currently in active production status with ROHS3 compliance and is supplied in Tape & Reel (TR) packaging format. Identifying equivalent substitute parts is necessary when the primary packaging format is unavailable or when alternative sourcing options are required while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The ADS7250IRTER has one parametric equivalent substitute: ADS7250IRTET. Both parts share identical electrical specifications across all critical parameters that determine functional compatibility:

• 12-bit resolution with 750 kSPS sampling rate
• 2 pseudo-differential inputs with 2 independent SAR converters
• SPI digital interface with simultaneous sampling capability
• Identical supply voltage requirements (5V analog, 1.65V ~ 5.5V digital)
• Same operating temperature range (-40°C ~ 125°C)
• Identical package footprint (16-WQFN 3x3 with exposed pad)
• Equivalent compliance certifications (ROHS3, REACH Unaffected, EAR99)

The substitution is valid based on packaging format differences only. The ADS7250IRTER is supplied in Tape & Reel (TR) format, while the ADS7250IRTET is available in Cut Tape (CT) & Digi-Reel® format. Both derive from the same base product number (ADS7250) and maintain full electrical and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the ADS7250IRTER and ADS7250IRTET are active production parts from Texas Instruments with full ROHS3 compliance and REACH Unaffected status. Selection between these parts should be based on packaging and supply chain requirements:

The ADS7250IRTER in Tape & Reel format is suitable for high-volume automated assembly operations where continuous reel feeding is required. The ADS7250IRTET in Cut Tape & Digi-Reel® format provides flexibility for lower-volume applications or mixed component sourcing scenarios. Both parts maintain identical electrical performance and thermal characteristics across the full operating temperature range. Compliance certifications (EAR99 ECCN classification) are equivalent for both variants.

Frequently Asked Questions (FAQ)

Q: Are the ADS7250IRTER and ADS7250IRTET electrically identical?

A: Yes. Both parts have identical electrical specifications including 12-bit resolution, 750 kSPS sampling rate, 2 pseudo-differential inputs, SPI interface, and supply voltage requirements. They are functionally interchangeable at the circuit level.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The ADS7250IRTER is supplied in Tape & Reel (TR) format for automated high-volume assembly. The ADS7250IRTET is supplied in Cut Tape (CT) & Digi-Reel® format for flexible sourcing and lower-volume applications.

Q: Can I substitute one part for the other on a PCB?

A: Yes. Both parts use the identical 16-WQFN (3x3) package with exposed pad and surface mount configuration. No PCB layout modifications are required for substitution.

Q: Do both parts have the same compliance certifications?

A: Yes. Both parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes. MSL rating is identical at Level 2 (1 Year) for both variants.

Q: Which part should I select for my application?

A: Selection depends on your assembly process and supply chain. Use ADS7250IRTER for automated reel-fed assembly lines. Use ADS7250IRTET for manual assembly, prototyping, or when sourcing from cut tape suppliers.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate across the identical temperature range (-40°C ~ 125°C) with identical thermal characteristics and performance specifications.
