ADS1610IPAPT Equivalent & Substitute Parts

Part Overview

The ADS1610IPAPT is a 16-bit Analog to Digital Converter featuring sigma-delta architecture with a single differential input and parallel data interface. Housed in a 64-HTQFP (10x10) surface mount package, this device operates with 5V analog supply and 2.7V to 3.6V digital supply, achieving a 10 MHz sampling rate. The ADS1610IPAPT carries a "Not For New Designs" product status, indicating it has been superseded in Texas Instruments' product portfolio. Identifying equivalent and substitute parts is essential for ongoing production support, legacy system maintenance, and design continuity where this component remains specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADS1610IPAPT is determined by strict alignment across the following critical parameters:

Core Functional Parameters:

• Resolution: 16-bit ADC architecture
• Input Configuration: Single differential input
• Data Interface: Parallel output
• Conversion Architecture: Sigma-Delta topology
• Package Type: 64-HTQFP (10x10) surface mount

Supply Voltage Compatibility:

• Analog Supply: 5V
• Digital Supply: 2.7V ~ 3.6V range (or compatible subset)

Environmental & Compliance:

• Operating Temperature Range: -40°C ~ 85°C
• RoHS3 Compliance
• MSL Rating: 3 (168 Hours)

The ADS1605IPAPT qualifies as a substitute based on matching these core parameters. While the ADS1605IPAPT operates at a reduced sampling rate of 5M (versus 10M for the ADS1610IPAPT) and offers both external and internal reference options, it maintains identical resolution, input configuration, data interface, package form factor, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

The ADS1605IPAPT is the designated substitute for the ADS1610IPAPT based on the following engineering criteria:

Product Status Alignment: The ADS1610IPAPT carries "Not For New Designs" status, while the ADS1605IPAPT maintains "Active" product status. This distinction makes the ADS1605IPAPT the appropriate choice for ongoing production and future applications requiring 16-bit sigma-delta ADC functionality.

Compliance & Certification: Both devices maintain identical RoHS3 compliance and MSL ratings, ensuring equivalent environmental and regulatory standing. No compliance degradation occurs with substitution.

Functional Compatibility: Identical resolution (16-bit), input configuration (single differential), data interface (parallel), and package form factor (64-HTQFP 10x10) ensure direct functional compatibility at the circuit board level.

Supply Voltage Consideration: The ADS1605IPAPT digital supply range (2.7V ~ 3.3V) is a subset of the ADS1610IPAPT range (2.7V ~ 3.6V). Applications operating at digital supply voltages above 3.3V require design verification before substitution.

Sampling Rate Trade-off: The ADS1605IPAPT operates at 5M sampling rate compared to the ADS1610IPAPT's 10M rate. Applications with sampling rate requirements exceeding 5M are not suitable for this substitution without system redesign.

Frequently Asked Questions (FAQ)

Q: Can the ADS1605IPAPT directly replace the ADS1610IPAPT in existing designs?

A: Direct replacement is possible only when the application's sampling rate requirement does not exceed 5M samples per second and the digital supply voltage remains within the 2.7V to 3.3V range. Pin-to-pin compatibility and identical package form factor enable mechanical and electrical interchangeability within these constraints.

Q: What is the primary difference between these two parts?

A: The ADS1605IPAPT operates at half the sampling rate (5M versus 10M) of the ADS1610IPAPT. Both devices share identical 16-bit resolution, differential input configuration, parallel data interface, and 64-HTQFP package specifications.

Q: Why is the ADS1610IPAPT marked "Not For New Designs"?

A: This designation indicates that Texas Instruments has transitioned this product to end-of-life status. The ADS1605IPAPT represents the active alternative within the same product family, offering continued manufacturing support and availability.

Q: Are there any reference voltage differences between these parts?

A: The ADS1610IPAPT supports external reference only, while the ADS1605IPAPT offers both external and internal reference options. Applications utilizing internal reference capability gain additional flexibility with the ADS1605IPAPT.

Q: What packaging options are available for the ADS1605IPAPT?

A: The ADS1605IPAPT is supplied in Cut Tape (CT) and Digi-Reel packaging, whereas the ADS1610IPAPT is supplied in Tape & Reel (TR) format. Both use the identical 64-HTQFP (10x10) component package.

Q: Are moisture sensitivity and RoHS compliance identical?

A: Yes. Both devices maintain MSL 3 (168 Hours) rating and ROHS3 compliance, ensuring equivalent handling requirements and regulatory standing.
