ADS1606IPAPRG4 Equivalent & Substitute Parts

Part Overview

The ADS1606IPAPRG4 is a 16-bit Sigma-Delta analog-to-digital converter manufactured by Texas Instruments, designed for single-channel differential input data acquisition applications. This device operates with a 5M samples-per-second sampling rate and supports both external and internal voltage references. The ADS1606IPAPRG4 carries an obsolete product status, making identification of functionally equivalent alternatives essential for ongoing design support and procurement planning.

Substitute Part Grouping Explanation

Substitution of the ADS1606IPAPRG4 is determined by strict equivalence across the following critical parameters: 16-bit resolution, 5M samples-per-second sampling rate, single differential input configuration, Sigma-Delta architecture, parallel data interface, 5V analog supply, 2.7V–3.3V digital supply, -40°C to 85°C operating temperature range, and 64-PowerTQFP package format.

The substitute parts are grouped into two categories:

Direct Packaging Substitute: ADS1606IPAPT differs only in packaging format (Tape & Reel versus the original Plastic Tray packaging) while maintaining identical electrical specifications and active product status.

Parametric Equivalents: ADS1605IPAPR and ADS1605IPAPT represent alternative base product numbers within the ADS160x family that maintain all critical electrical parameters, input configuration, and package specifications. These parts carry active product status and are available in alternative packaging formats.

Engineering Selection Recommendations

The ADS1606IPAPRG4 is classified as obsolete. All listed substitute parts maintain identical electrical specifications and are manufactured by Texas Instruments under active product status, ensuring long-term availability and supply chain continuity.

ADS1606IPAPT provides direct substitution with identical base product number and electrical performance, differing only in packaging format (Tape & Reel). This part is recommended for applications requiring the ADS1606 product line specifically.

ADS1605IPAPR and ADS1605IPAPT represent parametric equivalents within the ADS160x family. Both maintain all critical electrical parameters and package specifications while offering active product status. These parts are available in alternative packaging configurations (Plastic Tray and Cut Tape & Digi-Reel respectively) and support equivalent design implementation.

All substitute parts carry ROHS3 compliance and identical moisture sensitivity ratings, ensuring compatibility with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can ADS1605IPAPR and ADS1605IPAPT be used interchangeably with ADS1606IPAPRG4?

A: Yes. Both ADS1605 variants maintain identical electrical specifications across resolution, sampling rate, input configuration, supply voltages, and operating temperature range. The primary difference is the base product number (ADS1605 versus ADS1606) and packaging format. Electrical performance and pinout compatibility are equivalent.

Q: What is the difference between ADS1606IPAPT and ADS1606IPAPRG4?

A: The parts are electrically identical. ADS1606IPAPT is supplied in Tape & Reel packaging, while ADS1606IPAPRG4 uses Plastic Tray packaging. ADS1606IPAPT carries active product status, whereas ADS1606IPAPRG4 is obsolete.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting current environmental and regulatory requirements.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Plastic Tray, Tape & Reel, or Cut Tape & Digi-Reel) does not affect electrical performance, specifications, or functionality. Selection should be based on assembly process requirements and supply chain availability.

Q: What is the moisture sensitivity level, and why does it matter?

A: All parts carry Moisture Sensitivity Level 3 (168 Hours), indicating the component can be exposed to moisture for up to 168 hours at specified conditions before baking is required. This specification is critical for storage, handling, and assembly planning.
