ADS1610IPAPR Equivalent & Substitute Parts

Part Overview

The ADS1610IPAPR is a 16-bit Analog to Digital Converter featuring sigma-delta architecture with a single differential input and parallel data interface. Manufactured by Texas Instruments, this component is housed in a 64-HTQFP (10x10) surface mount package. The device operates with a 10 MHz sampling rate and supports both external and internal reference configurations.

The ADS1610IPAPR carries a "Not For New Designs" product status, indicating that Texas Instruments has discontinued active development and support for this component. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and access components with active manufacturer support and current inventory availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADS1610IPAPR is determined by the following critical parameters:

• Resolution: 16-bit conversion capability
• Input configuration: Single differential input
• Data interface: Parallel output
• Architecture: Sigma-delta modulation
• Reference options: External and internal reference support
• Analog supply voltage: 5V operation
• Digital supply voltage: 2.7V to 3.3V range
• Package: 64-HTQFP (10x10) surface mount form factor
• Temperature range: -40°C to 85°C industrial operating conditions

The ADS1605IPAPR qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is the sampling rate specification, which differs between the two components but does not preclude substitution in applications where the lower sampling rate is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The ADS1605IPAPR is the qualified substitute for the ADS1610IPAPR. Selection of the ADS1605IPAPR provides the following advantages:

• Active product status with ongoing manufacturer support from Texas Instruments
• Current inventory availability (3400 units in stock versus 928 units for the original part)
• Identical ROHS3 compliance and REACH unaffected status
• Matching MSL rating and thermal operating range
• Identical package footprint and pinout compatibility
• Full compatibility with existing PCB layouts and assembly processes

The ADS1605IPAPR operates at a 5 MHz sampling rate compared to the 10 MHz specification of the ADS1610IPAPR. This parameter difference must be evaluated against application-specific bandwidth and signal acquisition requirements to confirm suitability for the intended use case.

Frequently Asked Questions (FAQ)

Q: Can the ADS1605IPAPR be used as a direct replacement for the ADS1610IPAPR?

A: The ADS1605IPAPR is electrically and mechanically compatible with the ADS1610IPAPR. Both components share identical resolution, input configuration, reference options, supply voltage requirements, operating temperature range, and package specifications. The primary difference is the sampling rate. Substitution is valid when the application does not require the higher 10 MHz sampling rate of the original component.

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

A: The ADS1610IPAPR operates at a 10 MHz sampling rate, while the ADS1605IPAPR operates at 5 MHz. All other electrical and mechanical parameters are identical. The choice between these components depends on the maximum signal bandwidth that must be acquired in the application.

Q: Are the packages identical?

A: Yes. Both the ADS1610IPAPR and ADS1605IPAPR use the 64-HTQFP (10x10) surface mount package with identical pinout and footprint. No PCB layout modifications are required for substitution.

Q: What is the product status difference?

A: The ADS1610IPAPR is marked "Not For New Designs," indicating discontinued active development. The ADS1605IPAPR carries "Active" status, meaning Texas Instruments continues to manufacture and support this component. For new designs and long-term supply chain stability, the ADS1605IPAPR is the preferred choice.

Q: Are compliance certifications identical?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 3 (168 Hours). No compliance differences exist between the two parts.

Q: What supply voltages do these components require?

A: Both components require 5V for analog supply and 2.7V to 3.3V for digital supply. Power supply design remains unchanged when substituting between these parts.
