Key Parameters

Substitute Part Grouping Explanation

Substitution of the LT1722CS5#TRMPBF is determined by compatibility across the following critical parameters:

Package and Mounting Compatibility: Both the main part and substitute must support surface mount assembly in SOT-23-5 or equivalent thin-profile packages.

Supply Voltage Range: The substitute must operate within the 5 V to 10 V supply span of the LT1722CS5#TRMPBF, or provide a compatible range that encompasses this specification.

Output Current Capability: The substitute must deliver sufficient output current per channel to support the application requirements.

Amplifier Architecture: While the LT1722CS5#TRMPBF is a voltage feedback amplifier, current feedback amplifiers such as the AD8005ARTZ-REEL7 can serve as functional equivalents when bandwidth and slew rate requirements are met or exceeded.

Regulatory Compliance: Both parts must maintain ROHS3 compliance and REACH unaffected status for equivalent environmental qualification.

The AD8005ARTZ-REEL7 meets these substitution criteria through its SOT-23-5 package compatibility, extended supply voltage range (4 V to 12 V), and superior slew rate and bandwidth performance.

Engineering Selection Recommendations

Primary Substitute: AD8005ARTZ-REEL7

The AD8005ARTZ-REEL7 is the qualified substitute for the LT1722CS5#TRMPBF. Both devices are manufactured by Analog Devices Inc. and maintain active product status with ROHS3 compliance and unlimited moisture sensitivity rating.

The AD8005ARTZ-REEL7 provides enhanced performance characteristics including a slew rate of 280 V/µs (compared to 70 V/µs), a -3dB bandwidth of 270 MHz, and lower input offset voltage of 5 µV. The substitute operates across an extended supply voltage range of 4 V to 12 V, which encompasses the 5 V to 10 V requirement of the primary part.

The AD8005ARTZ-REEL7 is supplied in Cut Tape and Digi-Reel packaging with 3,400 units currently in stock, providing superior availability compared to the primary part.

Packaging Consideration: Both parts utilize SOT-23-5 surface mount packages with identical pinout compatibility, enabling direct board-level substitution without layout modification.

Compliance Status: Both parts maintain REACH unaffected status and EAR99 export classification, ensuring equivalent regulatory qualification for international applications.

Frequently Asked Questions (FAQ)

Q: Can the AD8005ARTZ-REEL7 directly replace the LT1722CS5#TRMPBF on existing PCB assemblies?

A: Yes. Both devices utilize identical SOT-23-5 surface mount packages with compatible pinout configurations, enabling direct substitution without PCB layout changes.

Q: What are the key electrical differences between these amplifiers?

A: The primary differences are amplifier architecture (voltage feedback versus current feedback) and performance metrics. The AD8005ARTZ-REEL7 provides 4× higher slew rate (280 V/µs versus 70 V/µs), 35× lower input offset voltage (5 µV versus 150 µV), and 9× lower supply current (400 µA versus 3.7 mA). The LT1722CS5#TRMPBF provides 5× higher output current per channel (50 mA versus 10 mA).

Q: Are both parts suitable for the same supply voltage range?

A: The AD8005ARTZ-REEL7 operates across 4 V to 12 V, which fully encompasses the 5 V to 10 V range of the LT1722CS5#TRMPBF. Applications designed for the primary part will operate within the substitute's specified supply range.

Q: What is the operating temperature difference between these parts?

A: The LT1722CS5#TRMPBF operates from 0°C to 70°C, while the AD8005ARTZ-REEL7 operates from -40°C to 85°C. The substitute provides extended temperature range coverage for applications requiring operation beyond the primary part's specification.

Q: Do both parts maintain equivalent regulatory compliance?

A: Yes. Both devices are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both parts.

Q: Which part should be selected for new designs?

A: Selection depends on specific application requirements. The AD8005ARTZ-REEL7 is preferred for applications requiring higher bandwidth, lower power consumption, or extended temperature operation. The LT1722CS5#TRMPBF is appropriate for applications requiring higher output current capability within the 0°C to 70°C operating range.

Q: What packaging options are available for each part?

A: The LT1722CS5#TRMPBF is supplied in Tape & Reel (TR) packaging. The AD8005ARTZ-REEL7 is supplied in Cut Tape (CT) and Digi-Reel packaging, providing flexibility in procurement quantities and handling methods.
