ADS1282IPWR Equivalent & Substitute Parts

Part Overview

The ADS1282IPWR is a 31-bit Sigma-Delta analog-to-digital converter manufactured by Texas Instruments, designed for precision data acquisition applications. This device features 2 differential inputs, external reference capability, and a programmable gain amplifier (PGA), operating across a wide temperature range of -40°C to 85°C. The part is currently in active production status with robust inventory availability. Alternative models become necessary when specific packaging formats, lead times, or supply chain constraints require substitution while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The ADS1282IPWR has one parametric equivalent substitute: ADS1282HIPWR. Both parts share identical electrical specifications across all critical parameters including resolution, sampling rate, input configuration, data interface, supply voltages, and operating temperature range. The substitution is valid based on the following key parameters that determine functional equivalence:

• 31-bit resolution
• 4k sampling rate per second
• 2 differential inputs
• SPI data interface
• Sigma-Delta architecture
• External reference type
• 5V analog supply and 1.65V ~ 3.6V digital supply
• PGA feature set
• 28-TSSOP package footprint
• Surface mount mounting type
• -40°C ~ 85°C operating temperature range

The primary difference between these parts lies in packaging format: ADS1282IPWR is supplied in Cut Tape (CT) & Digi-Reel® format, while ADS1282HIPWR is available in Tape & Reel (TR) packaging. Both maintain identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both ADS1282IPWR and ADS1282HIPWR are active production parts with full ROHS3 compliance and REACH unaffected status, making them suitable for current and future applications. Selection between these parts should be based on packaging and supply chain requirements rather than electrical performance, as they are functionally identical.

The ADS1282IPWR in Cut Tape format is appropriate for lower-volume applications, prototype development, and situations requiring flexible component quantities. The ADS1282HIPWR in Tape & Reel format is optimized for high-volume manufacturing and automated assembly processes. Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.

Frequently Asked Questions (FAQ)

Q: Are ADS1282IPWR and ADS1282HIPWR electrically interchangeable?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, including resolution, sampling rate, input configuration, supply voltages, and operating temperature range. They can be used interchangeably in circuit designs without modification.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging supplies components on individual tape segments, suitable for small quantities and manual handling. Tape & Reel (TR) packaging provides components on continuous reels optimized for automated pick-and-place assembly equipment used in high-volume manufacturing.

Q: Can I substitute ADS1282IPWR with ADS1282HIPWR in an existing design?

A: Yes, provided your assembly process can accommodate Tape & Reel packaging. The mechanical footprint, pin configuration, and electrical performance are identical. Verify that your manufacturing equipment supports the reel format.

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

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL rating 1 (Unlimited). They are equivalent from a regulatory and environmental standpoint.

Q: Which part should I select for new designs?

A: Selection depends on production volume and assembly capabilities. For prototype and low-volume applications, ADS1282IPWR in Cut Tape format provides flexibility. For production runs with automated assembly, ADS1282HIPWR in Tape & Reel format offers cost efficiency and process optimization.
