AD8062ARMZ Equivalent & Substitute Parts

Part Overview

The AD8062ARMZ is a voltage feedback amplifier manufactured by Analog Devices Inc., configured as a dual-circuit (2-channel) rail-to-rail operational amplifier in an 8-MSOP surface mount package. This device is classified as Active product status and is RoHS3 compliant. The AD8062ARMZ is supplied in tube packaging and maintains full operational capability across the industrial temperature range of -40°C to 85°C.

Substitute parts are identified when equivalent functional performance can be achieved through alternative amplifier topologies or performance grades while maintaining mechanical and electrical compatibility within the 8-MSOP package form factor and surface mount mounting type.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AD8062ARMZ are identified from the LTC6244 family of CMOS amplifiers. Substitution is valid based on the following criteria:

Mechanical Compatibility:

• Identical package type: 8-MSOP (0.118", 3.00mm Width)
• Identical mounting type: Surface Mount
• Identical number of circuits: 2
• Identical output type: Rail-to-Rail

Electrical Compatibility:

• Voltage supply span overlap: LTC6244 series operates within 2.8V to 6V, which overlaps with the AD8062ARMZ supply range of 2.7V to 8V
• Both devices support dual-channel configuration
• Both devices are Active product status
• Both devices are RoHS3 compliant and REACH unaffected

Performance Trade-offs: The LTC6244 series represents a different amplifier topology (CMOS versus Voltage Feedback) with reduced slew rate (35V/µs versus 650V/µs) and reduced bandwidth (50 MHz gain-bandwidth product versus 320 MHz -3dB bandwidth). These substitutes are applicable in applications where the lower performance specifications are acceptable and the superior input bias current characteristics (1 pA versus 3.5 µA) provide system-level advantages.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and full RoHS3 compliance with REACH unaffected designation, ensuring regulatory alignment with the primary AD8062ARMZ device.

LTC6244CMS8#PBF is suitable for applications operating within the commercial temperature range (0°C to 70°C) where the reduced slew rate and bandwidth specifications are acceptable. This variant provides the lowest supply voltage maximum specification at 6V.

LTC6244HMS8#PBF and LTC6244HMS8#TRPBF extend the operating temperature range to -40°C to 125°C, accommodating extended industrial and military temperature specifications. The TRPBF variant is supplied in Tape & Reel packaging, while the PBF variant is supplied in tube packaging. Both maintain identical electrical specifications.

LTC6244IMS8#PBF operates across the -40°C to 85°C temperature range, matching the AD8062ARMZ operating temperature specification. This variant is supplied in tube packaging and represents the closest temperature-range equivalent to the primary device.

Selection between substitute parts should be based on required operating temperature range and packaging format (tube versus Tape & Reel) rather than electrical performance, as all LTC6244 variants share identical electrical characteristics within their respective temperature ratings.

Frequently Asked Questions (FAQ)

Q: Can the LTC6244 series directly replace the AD8062ARMZ in all applications?

A: Direct replacement is valid only in applications where the reduced slew rate (35V/µs versus 650V/µs) and reduced bandwidth (50 MHz gain-bandwidth product versus 320 MHz -3dB bandwidth) do not compromise system performance. The LTC6244 series offers superior input bias current characteristics (1 pA versus 3.5 µA), which may provide system-level advantages in high-impedance input circuits.

Q: What is the significance of the packaging designation differences (PBF, TRPBF)?

A: PBF indicates tube packaging, while TRPBF indicates Tape & Reel packaging. Both packaging formats contain identical electronic components. Selection depends on manufacturing process requirements and component handling equipment compatibility. Tape & Reel packaging is typically used for automated assembly processes, while tube packaging is used for manual assembly or lower-volume applications.

Q: Are there temperature range limitations when substituting the AD8062ARMZ?

A: The AD8062ARMZ operates from -40°C to 85°C. The LTC6244CMS8#PBF is limited to 0°C to 70°C and is not suitable for applications requiring the full -40°C to 85°C range. The LTC6244IMS8#PBF matches the AD8062ARMZ temperature range exactly. The LTC6244HMS8#PBF and LTC6244HMS8#TRPBF extend to -40°C to 125°C and are suitable for all temperature conditions required by the AD8062ARMZ.

Q: What are the supply voltage compatibility considerations?

A: The AD8062ARMZ operates from 2.7V to 8V. All LTC6244 substitutes operate from 2.8V to 6V. Applications requiring supply voltages above 6V or below 2.8V cannot use LTC6244 substitutes. Applications operating within the 2.8V to 6V window are compatible with both device families.

Q: How do the output current specifications compare?

A: The AD8062ARMZ provides 50 mA per channel output current, while all LTC6244 variants provide 35 mA per channel. Applications requiring output currents exceeding 35 mA per channel cannot use LTC6244 substitutes.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (LTC6244CMS8#PBF, LTC6244HMS8#PBF, LTC6244HMS8#TRPBF, and LTC6244IMS8#PBF) are RoHS3 compliant and REACH unaffected, matching the regulatory status of the AD8062ARMZ.
