ADS801UG4 Equivalent & Substitute Parts

Part Overview

The ADS801UG4 is a 12-bit pipelined analog-to-digital converter manufactured by Texas Instruments, housed in a 28-SOIC surface mount package. This device features a single differential or single-ended input with a 25 MHz sampling rate and operates on 5V analog and digital supply voltages across an industrial temperature range of -40°C to 85°C.

The ADS801UG4 is classified as obsolete. Locating equivalent or substitute components is necessary for new designs, production continuity, or system upgrades where this part is no longer readily available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ADS801UG4 is determined by strict equivalence across the following critical parameters:

• 12-bit resolution
• 25 MHz sampling rate
• Single input channel
• Differential and single-ended input capability
• Pipelined architecture
• Parallel data interface
• 28-SOIC package footprint
• Surface mount configuration
• Industrial temperature range (-40°C to 85°C)
• RoHS3 compliance

Two substitute parts meet these criteria:

AD9225ARZ (Analog Devices Inc.) – MFR Recommended substitute with active product status and superior digital supply voltage flexibility (2.85V to 5.25V).

ADS801U (Texas Instruments) – Parametric equivalent from the same manufacturer with last-time-buy status.

Parameter Comparison

Engineering Selection Recommendations

AD9225ARZ is the primary substitute for new designs and production continuity. This part carries active product status, ensuring long-term availability and supply chain stability. The digital supply voltage range of 2.85V to 5.25V provides greater design flexibility compared to the fixed 5V requirement of the ADS801UG4. Moisture sensitivity level 1 with unlimited shelf life offers superior storage and handling characteristics. All electrical and mechanical parameters align with the original specification.

ADS801U serves as a secondary parametric equivalent from Texas Instruments. This part maintains identical electrical specifications and package configuration but carries last-time-buy status, indicating limited future availability. Selection of this part is appropriate only when supply chain continuity from a single manufacturer is required and existing inventory can be secured.

Both substitutes maintain full RoHS3 compliance and industrial temperature range operation, ensuring regulatory and environmental compatibility with the original ADS801UG4 specification.

Frequently Asked Questions (FAQ)

Q: Can AD9225ARZ be used as a direct replacement for ADS801UG4 in existing designs?

A: Yes. The AD9225ARZ matches all critical electrical parameters: 12-bit resolution, 25 MHz sampling rate, single input channel, differential and single-ended input capability, pipelined architecture, and parallel data interface. The 28-SOIC package footprint is identical, enabling direct PCB compatibility. The digital supply voltage range of 2.85V to 5.25V encompasses the original 5V specification, ensuring functional equivalence.

Q: What is the difference between AD9225ARZ and ADS801U?

A: Both parts are parametrically equivalent to the ADS801UG4. The primary distinction is product status and supply voltage specification. AD9225ARZ (Analog Devices) is active and offers digital supply flexibility (2.85V to 5.25V). ADS801U (Texas Instruments) is last-time-buy with fixed 5V digital supply. AD9225ARZ also provides superior moisture sensitivity characteristics (MSL 1 vs. MSL 2).

Q: Are there any package or pinout differences between these parts?

A: No. All three parts use the 28-SOIC (0.295", 7.50mm Width) surface mount package. Pinout compatibility is maintained across ADS801UG4, AD9225ARZ, and ADS801U.

Q: What does "last-time-buy" status mean for ADS801U?

A: Last-time-buy indicates that Texas Instruments has announced the end of production for this part. Existing inventory may be available through authorized distributors, but future availability is not guaranteed. This status makes ADS801U suitable only for applications where immediate supply can be secured and long-term production continuity is not required.

Q: Is AD9225ARZ suitable for long-term production use?

A: Yes. AD9225ARZ carries active product status, indicating ongoing manufacturing and distribution support. This part is appropriate for new designs and applications requiring extended production runs and supply chain stability.

Q: Do all three parts meet the same compliance standards?

A: Yes. ADS801UG4, AD9225ARZ, and ADS801U are all ROHS3 compliant and REACH unaffected. All parts operate across the industrial temperature range of -40°C to 85°C and carry the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications.
