Substitute Part Grouping Explanation

Substitution of the AD8519ARTZ-REEL is determined by electrical and mechanical compatibility across the following critical parameters:

Package Compatibility: All substitute parts maintain the SOT-23-5 surface mount package format, ensuring mechanical and thermal compatibility with existing PCB layouts.

Functional Parameters: Substitute parts must support single-circuit amplification with rail-to-rail output capability and operate within the 2.7 V to 12 V supply voltage range.

Electrical Characteristics: Substitutes are grouped based on slew rate, gain bandwidth product, input bias current, and output current capacity. The AD8519ARTZ-REEL operates at 2.9 V/µs slew rate with 8 MHz gain bandwidth product. Substitute parts from the LT1797 series operate at 2.5 V/µs slew rate with 11 MHz gain bandwidth product, representing comparable performance within general purpose amplifier specifications. The TSH80IYLT from STMicroelectronics operates at significantly higher performance levels (118 V/µs slew rate, 65 MHz gain bandwidth product) and is suitable for applications requiring enhanced bandwidth and slew rate performance.

Temperature Range: Operating temperature ranges vary among substitutes. The LT1797 series variants support either 0°C to 70°C or -40°C to 85°C ranges. The TSH80IYLT supports -40°C to 85°C operation. Selection depends on application temperature requirements.

Product Status: All substitute parts listed are active products with ongoing manufacturer support, contrasting with the obsolete status of the AD8519ARTZ-REEL.

Engineering Selection Recommendations

LT1797 Series (LT1797CS5#TRMPBF, LT1797CS5#TRPBF, LT1797IS5#TRMPBF, LT1797IS5#TRPBF):

The LT1797 series from Analog Devices Inc. represents the primary substitute family for the AD8519ARTZ-REEL. All variants are active products with ROHS3 compliance and REACH unaffected status. The LT1797 series maintains functional equivalence through single-circuit rail-to-rail amplification within the 2.7 V to 12 V supply range. Performance characteristics are comparable, with 11 MHz gain bandwidth product and 2.5 V/µs slew rate. Selection among LT1797 variants depends on operating temperature requirements and packaging specifications. The CS5 variants support 0°C to 70°C operation, while IS5 variants extend to -40°C to 85°C. The TRMPBF and TRPBF suffixes indicate tape and reel packaging with lead-free plating.

TSH80IYLT:

The TSH80IYLT from STMicroelectronics is an active general purpose amplifier suitable for applications requiring enhanced performance. This device operates at 118 V/µs slew rate and 65 MHz gain bandwidth product, providing significantly higher bandwidth and slew rate performance than the AD8519ARTZ-REEL. The TSH80IYLT maintains rail-to-rail output and single-circuit configuration. This part is qualified to AEC-Q100 automotive standards and supports -40°C to 85°C operation. The TSH80IYLT requires minimum supply voltage of 4.5 V, which differs from the 2.7 V minimum of the AD8519ARTZ-REEL. Selection of the TSH80IYLT is appropriate for applications where higher bandwidth and slew rate performance are required and supply voltage constraints permit 4.5 V minimum operation. All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity classification and SOT-23-5 package compatibility.

Frequently Asked Questions (FAQ)

Q: Can the LT1797 series directly replace the AD8519ARTZ-REEL in existing designs?

A: The LT1797 series maintains mechanical and electrical compatibility through identical SOT-23-5 package format and rail-to-rail single-circuit amplification within the 2.7 V to 12 V supply range. Pin configuration and functional operation are compatible. Differences in slew rate (2.5 V/µs versus 2.9 V/µs) and gain bandwidth product (11 MHz versus 8 MHz) represent performance improvements. Operating temperature range varies by LT1797 variant; CS5 variants support 0°C to 70°C while IS5 variants support -40°C to 85°C. Selection of the appropriate LT1797 variant depends on application temperature requirements.

Q: What is the difference between LT1797CS5 and LT1797IS5 variants?

A: The primary difference is operating temperature range. LT1797CS5 variants operate from 0°C to 70°C, suitable for commercial temperature applications. LT1797IS5 variants operate from -40°C to 85°C, suitable for industrial and extended temperature applications. All other electrical and mechanical parameters are identical between these variants.

Q: What does the TRMPBF and TRPBF suffix indicate?

A: The TR suffix indicates tape and reel packaging format. The MPBF suffix indicates lead-free plating with matte finish, while PBF indicates lead-free plating with bright finish. Both are ROHS3 compliant. Selection between these packaging variants depends on assembly equipment compatibility and handling requirements.

Q: When should the TSH80IYLT be selected over LT1797 variants?

A: The TSH80IYLT is selected when applications require higher bandwidth (65 MHz gain bandwidth product versus 11 MHz) and faster slew rate (118 V/µs versus 2.5 V/µs). The TSH80IYLT is qualified to AEC-Q100 automotive standards, making it suitable for automotive applications. The TSH80IYLT requires minimum supply voltage of 4.5 V, which differs from the 2.7 V minimum of the AD8519ARTZ-REEL and LT1797 series. Applications with supply voltages below 4.5 V cannot use the TSH80IYLT.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed (LT1797 series and TSH80IYLT) are ROHS3 compliant. The original AD8519ARTZ-REEL does not specify RoHS status. All substitute parts are REACH unaffected.

Q: What is the moisture sensitivity level for these parts?

A: All parts, including the AD8519ARTZ-REEL and all substitute parts, maintain MSL 1 (Unlimited) moisture sensitivity classification. This indicates unlimited shelf life without moisture control requirements.

Q: Can the TSH80IYLT be used in applications designed for 2.7 V supply voltage?

A: No. The TSH80IYLT requires minimum supply voltage of 4.5 V and cannot operate at the 2.7 V minimum specified for the AD8519ARTZ-REEL. Applications with 2.7 V to 4.4 V supply voltage must use the AD8519ARTZ-REEL or LT1797 series substitutes.

Q: What inventory levels are available for substitute parts?

A: Inventory availability varies by part number. LT1797CS5#TRMPBF has 6021 pieces in stock, LT1797CS5#TRPBF has 6900 pieces, LT1797IS5#TRMPBF has 2100 pieces, LT1797IS5#TRPBF has 2436 pieces, and TSH80IYLT has 65100 pieces in stock. The original AD8519ARTZ-REEL has 34853 pieces in stock but is obsolete.
