ADS7279IPWG4 Equivalent & Substitute Parts

Part Overview

The ADS7279IPWG4 is a 14-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for single-channel data acquisition applications. It features a Successive Approximation Register (SAR) architecture with a 1 MHz sampling rate and supports both pseudo-differential and single-ended input configurations. The device operates with a 5V analog supply and digital supply range of 1.65V to 5.5V, packaged in a 16-TSSOP surface mount configuration.

The ADS7279IPWG4 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and replacement applications.

Substitute Part Grouping Explanation

Substitution of the ADS7279IPWG4 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following key areas:

Resolution and Sampling Performance: 14-bit resolution with 1 MHz sampling rate Input Configuration: Single input channel supporting pseudo-differential and single-ended modes Data Interface: SPI and DSP protocol support Power Supply Requirements: 5V analog supply and 1.65V to 5.5V digital supply range Package and Mounting: 16-TSSOP surface mount package with identical physical dimensions Environmental Compliance: ROHS3 compliance and MSL 2 rating Operating Temperature: -40°C to 85°C range

The ADS7279IPW qualifies as a direct substitute based on complete parameter alignment across all specified criteria.

Parameter Comparison

Engineering Selection Recommendations

The ADS7279IPW is the qualified substitute for the discontinued ADS7279IPWG4. Both parts share identical electrical specifications, package configuration, and compliance certifications. The primary distinction is product status: the ADS7279IPWG4 is discontinued, while the ADS7279IPW maintains active production status with confirmed inventory availability.

Selection of the ADS7279IPW ensures continued access to equivalent functionality without design modification. Both parts maintain ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for industrial and commercial applications. The active production status of the ADS7279IPW provides supply chain continuity for new designs and replacement components.

Frequently Asked Questions (FAQ)

Q: Can the ADS7279IPW directly replace the ADS7279IPWG4 without PCB modifications?

A: Yes. Both parts are identical in electrical performance, pin configuration, and package dimensions (16-TSSOP). No PCB layout changes are required for substitution.

Q: What is the difference between the ADS7279IPWG4 and ADS7279IPW part numbers?

A: Both parts are based on the ADS7279 base product number. The suffix variations indicate different packaging or distribution channels. The electrical and functional specifications are equivalent.

Q: Is the ADS7279IPW available in the same packaging format?

A: The ADS7279IPW is supplied in Tube packaging, while the ADS7279IPWG4 packaging format was not specified. Both use the identical 16-TSSOP surface mount package for PCB assembly.

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

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 2, 1 Year). Regulatory requirements are equivalent.

Q: What is the inventory status for the substitute part?

A: The ADS7279IPW has 2057 units in stock with active product status, ensuring availability for immediate procurement and production use.
