Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADS8320EB/250G4 is determined by the following critical parameters:

• Resolution: 16-bit conversion capability
• Sampling Rate: 100 kSPS minimum performance
• Input Configuration: Single input with pseudo-differential or single-ended capability
• Data Interface: SPI protocol compatibility
• Architecture: SAR (Successive Approximation Register) topology
• Reference Type: External reference requirement
• Supply Voltage: 5V analog and digital supply compatibility
• Operating Temperature Range: -40°C to 85°C
• Package Compatibility: 8-pin surface mount (8-VSSOP, 8-TSSOP, or 8-MSOP)
• Compliance: ROHS3 compliance and EAR99 classification

Substitute parts are grouped into two categories:

MFR Recommended Substitute: ADS8320EB/250 maintains identical electrical specifications and is the direct packaging variant (Cut Tape & Digi-Reel) of the same base product.

Parametric Equivalent Substitutes: ADS8320E/2K5 and AD7683ARMZRL7 meet all critical electrical and functional parameters while offering extended availability and alternative packaging options.

Parameter Comparison

Engineering Selection Recommendations

ADS8320EB/250 is the primary recommended substitute. This part is the direct equivalent with identical electrical specifications and is currently in active production status. It differs only in packaging format (Cut Tape & Digi-Reel vs. Digi-Reel) and offers superior inventory availability (1492 units in stock).

ADS8320E/2K5 is a parametric equivalent within the same Texas Instruments microPOWER™ series. All critical electrical parameters match the original specification. This part maintains the highest inventory level (10204 units) and is actively produced, providing long-term supply security.

AD7683ARMZRL7 is a cross-manufacturer parametric equivalent from Analog Devices Inc., part of the PulSAR® series. This device meets all functional requirements with the following distinctions: it supports extended supply voltage range (2.7V to 5.5V vs. fixed 5V), includes DSP interface capability in addition to SPI, and features improved moisture sensitivity rating (MSL 1 vs. MSL 2). The 8-MSOP package variant requires PCB layout verification for pin compatibility. All parts maintain ROHS3 compliance and EAR99 classification.

Frequently Asked Questions (FAQ)

Q: Can ADS8320EB/250 be used as a direct replacement for ADS8320EB/250G4?

A: Yes. ADS8320EB/250 is electrically and functionally identical to the original part. The difference is packaging format (Cut Tape & Digi-Reel vs. Digi-Reel). Both use the 8-VSSOP package and are pin-compatible.

Q: What is the difference between ADS8320EB/250 and ADS8320E/2K5?

A: Both are Texas Instruments 16-bit, 100 kSPS SAR ADCs with identical electrical specifications. The difference is in packaging format and tape reel configuration. ADS8320E/2K5 offers higher inventory availability.

Q: Can AD7683ARMZRL7 replace the ADS8320EB/250G4 in a 5V-only system?

A: Yes. AD7683ARMZRL7 operates at 5V supply and meets all functional requirements. However, it uses an 8-MSOP package instead of 8-VSSOP. PCB layout and pin assignment must be verified for compatibility.

Q: What is the advantage of AD7683ARMZRL7 over the Texas Instruments alternatives?

A: AD7683ARMZRL7 provides extended supply voltage range (2.7V to 5.5V), enabling use in lower-voltage applications. It also includes DSP interface support and has a superior moisture sensitivity rating (MSL 1 vs. MSL 2).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitutes maintain ROHS3 compliance and are classified as EAR99 for export purposes.

Q: What is the operating temperature range for all substitutes?

A: All substitute parts operate across the -40°C to 85°C temperature range, matching the original specification.

Q: Do the substitute parts require different PCB layout considerations?

A: ADS8320EB/250 and ADS8320E/2K5 use identical 8-VSSOP packaging and require no layout changes. AD7683ARMZRL7 uses 8-MSOP packaging; pin assignments must be verified against the original design before implementation.
