Substitute Part Grouping Explanation

Substitute parts for the AD8063ARTZ-REEL are grouped into two categories based on substitution compatibility:

Direct Substitutes (Identical Electrical Performance): Parts that maintain the same amplifier type (voltage feedback), circuit count (1), output configuration (rail-to-rail), slew rate (650V/µs), bandwidth (320 MHz), and package (SOT-23-6). These parts are pin-compatible and functionally equivalent for direct replacement.

Functional Equivalents (Similar Performance, Different Characteristics): Parts that provide rail-to-rail output in SOT-23-6 packaging with comparable or superior electrical performance but differ in amplifier type (J-FET, CMOS, or general purpose), slew rate, bandwidth, or supply voltage specifications. These require circuit evaluation for compatibility.

Key Parameters Determining Substitution:

Package type (SOT-23-6 or TSOT-23-6)
Output type (rail-to-rail)
Number of circuits (1)
Supply voltage range compatibility
Operating temperature range
Slew rate and bandwidth requirements
Input bias current and offset voltage specifications

Engineering Selection Recommendations

Primary Recommendation: AD8063ARTZ-REEL7

The AD8063ARTZ-REEL7 is the direct active equivalent of the obsolete AD8063ARTZ-REEL. Both parts share identical electrical specifications including voltage feedback amplifier type, 650V/µs slew rate, 320 MHz bandwidth, and SOT-23-6 packaging. The AD8063ARTZ-REEL7 is classified as active with ROHS3 compliance and REACH unaffected status, making it suitable for new designs and production continuity.

Secondary Recommendations: OPA355NA Series (OPA355NA/3K, OPA355NA/250)

The OPA355NA series from Texas Instruments provides CMOS amplifier technology in SOT-23-6 packaging with superior slew rate (360V/µs) and bandwidth (450 MHz) compared to the original part. Supply voltage range (2.7V to 5.5V) overlaps with the AD8063ARTZ-REEL specification. Both variants are active with ROHS3 compliance. The OPA355NA/3K variant has higher inventory availability (35,300 units).

Alternative Consideration: LTC6268 Series (LTC6268IS6#TRMPBF, LTC6268HS6#TRMPBF)

The LTC6268 J-FET amplifiers from Analog Devices provide rail-to-rail output in TSOT-23-6 packaging with extended operating temperature range (-40°C to 125°C). These parts feature significantly lower input bias current (0.9 pA to 4 pA) and higher bandwidth (350 MHz) but operate at reduced slew rate (400V/µs) and narrower supply voltage range (3.1V to 5.25V). Selection requires verification of supply voltage compatibility and slew rate requirements.

Not Recommended: LMV824M/NOPB, MCP6043T Series

The LMV824M/NOPB is a 4-circuit amplifier in 14-SOIC packaging, incompatible with single-circuit SOT-23-6 requirements. The MCP6043T series exhibits extremely low slew rate (0.003V/µs) and bandwidth specifications unsuitable for high-speed applications requiring 320 MHz or greater performance.

Frequently Asked Questions (FAQ)

Q: Can AD8063ARTZ-REEL7 be used as a direct replacement for AD8063ARTZ-REEL?

A: Yes. The AD8063ARTZ-REEL7 is electrically and mechanically identical to the obsolete AD8063ARTZ-REEL. Both parts feature voltage feedback amplifier topology, 650V/µs slew rate, 320 MHz bandwidth, and SOT-23-6 packaging. The primary difference is product status (active vs. obsolete) and packaging format (Digi-Reel vs. standard reel).

Q: What are the key differences between OPA355NA and AD8063ARTZ-REEL?

A: The OPA355NA uses CMOS amplifier technology versus the voltage feedback design of the AD8063ARTZ-REEL. The OPA355NA provides higher slew rate (360V/µs vs. 650V/µs) and bandwidth (450 MHz vs. 320 MHz), lower input bias current (3 pA vs. 3.5 µA), and narrower maximum supply voltage (5.5V vs. 8V). Both are SOT-23-6 packaged and rail-to-rail output.

Q: Are LTC6268 parts compatible with AD8063ARTZ-REEL applications?

A: LTC6268 parts provide functional equivalence in SOT-23-6 packaging with rail-to-rail output but differ significantly in amplifier type (J-FET), slew rate (400V/µs), and supply voltage range (3.1V to 5.25V). Applications requiring the full 8V maximum supply or 650V/µs slew rate performance must evaluate circuit-level compatibility before substitution.

Q: What is the difference between LTC6268IS6#TRMPBF and LTC6268HS6#TRMPBF?

A: Both parts are J-FET amplifiers in TSOT-23-6 packaging with identical slew rate (400V/µs) and bandwidth (350 MHz). The primary difference is input bias current: LTC6268IS6#TRMPBF specifies 0.9 pA while LTC6268HS6#TRMPBF specifies 4 pA. The LTC6268IS6#TRMPBF variant has higher inventory availability (100,400 units).

Q: Why is package type important for substitution?

A: Package type determines physical compatibility with printed circuit board layouts and assembly processes. The AD8063ARTZ-REEL uses SOT-23-6 packaging. Substitute parts must use SOT-23-6 or TSOT-23-6 (thin variant) to maintain footprint compatibility. Parts in alternative packages (14-SOIC) require board redesign and are not direct substitutes.

Q: What supply voltage range should be considered when selecting a substitute?

A: The AD8063ARTZ-REEL operates from 2.7V to 8V. Substitute parts must support the supply voltage range of the target application. OPA355NA parts support 2.7V to 5.5V, which covers most applications but cannot reach the 8V maximum of the original part. LTC6268 parts support 3.1V to 5.25V, requiring verification for applications using 2.7V minimum supply.

Q: Are there RoHS and REACH compliance considerations for substitution?

A: All recommended active substitute parts (AD8063ARTZ-REEL7, OPA355NA series, LTC6268 series) are ROHS3 compliant and REACH unaffected. The obsolete AD8063ARTZ-REEL does not specify these certifications. New designs should utilize active parts with current compliance documentation.

Q: What is the significance of operating temperature range differences?

A: The AD8063ARTZ-REEL operates from -40°C to 85°C. Some substitutes (OPA355NA, LTC6268HS6#TRPBF) extend to -40°C to 125°C, providing wider temperature coverage. Applications limited to -40°C to 85°C can use any substitute; applications requiring extended temperature range should select parts with -40°C to 125°C specification.
