ADS1672IPAGG4 Equivalent & Substitute Parts

Part Overview

The ADS1672IPAGG4 is a 24-bit Analog to Digital Converter (ADC) featuring sigma-delta architecture with a single differential input and 625 kSPS sampling rate. Manufactured by Texas Instruments, this device is packaged in a 64-TQFP (10x10) surface mount configuration and operates across -40°C to 85°C. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADS1672IPAGG4 is determined by strict equivalence across the following critical parameters:

• Resolution & Sampling Rate: 24-bit resolution at 625 kSPS
• Input Configuration: Single differential input
• Data Interface: LVDS-Serial and SPI compatibility
• Architecture: Sigma-Delta ADC topology
• Supply Voltages: 5V analog and 2.7V–3.3V digital rails
• Package & Pinout: 64-TQFP (10x10) surface mount form factor
• Environmental Compliance: ROHS3 compliance and MSL 4 rating

The ADS1672IPAG qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is packaging format (Tray vs. standard packaging) and product status (Active vs. Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The ADS1672IPAG is the direct equivalent substitute for the discontinued ADS1672IPAGG4. Both devices share identical electrical specifications, pinout, and package geometry. The ADS1672IPAG maintains active product status with established supply chain availability, ensuring long-term procurement viability.

The ADS1672IPAG offers an additional reference type option (Internal reference capability) compared to the main part, which provides design flexibility without compromising backward compatibility. Both parts maintain equivalent ROHS3 compliance and MSL 4 ratings, ensuring consistent handling and environmental performance.

Frequently Asked Questions (FAQ)

Q: Can the ADS1672IPAG directly replace the ADS1672IPAGG4 in existing designs?

A: Yes. Both parts are pin-compatible 64-TQFP devices with identical electrical specifications, sampling rates, resolution, and supply voltage requirements. No circuit modifications are required.

Q: What is the difference between ADS1672IPAGG4 and ADS1672IPAG?

A: The primary differences are packaging format (standard vs. Tray) and product status (Discontinued vs. Active). The ADS1672IPAG also supports both external and internal reference types, whereas the main part supports external reference only. All core ADC functionality remains identical.

Q: Are there any thermal or environmental considerations when substituting these parts?

A: Both parts operate across -40°C to 85°C and carry MSL 4 ratings with 72-hour moisture sensitivity windows. Handling and storage requirements are equivalent.

Q: Does the internal reference capability of the ADS1672IPAG affect compatibility?

A: No. The internal reference is an additional feature that does not impact designs using external reference configurations. Existing external reference circuits remain fully compatible.

Q: What is the base product number for these devices?

A: Both the ADS1672IPAGG4 and ADS1672IPAG share the base product number ADS1672, indicating they are variants within the same product family.
