AD549JHZ Equivalent & Substitute Parts

Part Overview

The AD549JHZ is a general purpose operational amplifier manufactured by Analog Devices Inc., housed in a TO-99-8 metal can package for through-hole mounting. This device is classified as a linear amplifier with a single circuit configuration and is currently in active product status. The AD549JHZ serves applications requiring low input bias current and precision amplification in environments where through-hole mounting and metal can packaging are specified requirements. Substitute parts become necessary when design constraints change regarding package type, mounting technology, operating temperature range, or supply voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD549JHZ is determined by compatibility across the following critical parameters: amplifier type classification, number of circuits, supply voltage range, operating temperature range, output current capability, and compliance certifications. The AD549JHZ operates within a 10 V to 36 V supply range and a 0°C to 70°C temperature window.

The substitute parts identified are:

ADA4530-1ARZ (Analog Devices Inc.): This general purpose amplifier shares the same manufacturer and single-circuit configuration. It operates within a 4.5 V to 16 V supply range and an extended -40°C to 125°C temperature range. The ADA4530-1ARZ features rail-to-rail output capability and surface mount 8-SOIC packaging, representing a modern alternative with improved specifications in gain bandwidth product (2 MHz versus 1 MHz) and input offset voltage (8 µV versus 500 µV).

INA828ID (Texas Instruments): This instrumentation amplifier from Texas Instruments operates within a 4.5 V to 36 V supply range and an extended -40°C to 125°C temperature range. The INA828ID is housed in surface mount 8-SOIC packaging. While classified as an instrumentation amplifier rather than general purpose, it shares compatible supply voltage specifications with the AD549JHZ and maintains the same supply current (600 µA).

Parameter Comparison

Engineering Selection Recommendations

ADA4530-1ARZ Selection Criteria: The ADA4530-1ARZ is suitable for applications transitioning from through-hole to surface mount assembly. Both devices are manufactured by Analog Devices Inc. and maintain ROHS3 compliance. The ADA4530-1ARZ operates within a reduced maximum supply voltage of 16 V, which limits its use to designs not requiring the full 36 V capability of the AD549JHZ. The extended operating temperature range (-40°C to 125°C) accommodates industrial and automotive environments beyond the AD549JHZ specification. The ADA4530-1ARZ features rail-to-rail output capability and superior input offset voltage performance (8 µV versus 500 µV).

INA828ID Selection Criteria: The INA828ID is suitable for applications requiring instrumentation amplifier functionality with extended operating temperature range. The INA828ID maintains compatibility with the full 4.5 V to 36 V supply voltage range of the AD549JHZ and operates across -40°C to 125°C. This device is appropriate for precision measurement and signal conditioning applications. The INA828ID carries a Moisture Sensitivity Level of 2 (1 Year), which differs from the AD549JHZ MSL of 1 (Unlimited), requiring consideration in storage and handling protocols.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the AD549JHZ regulatory classification.

Frequently Asked Questions (FAQ)

Q: Can the ADA4530-1ARZ directly replace the AD549JHZ in existing through-hole PCB designs?

A: No. The ADA4530-1ARZ uses surface mount 8-SOIC packaging, while the AD549JHZ uses through-hole TO-99-8 metal can packaging. PCB layout and assembly process modifications are required. Additionally, the ADA4530-1ARZ maximum supply voltage is 16 V, which may not accommodate designs requiring the full 36 V capability of the AD549JHZ.

Q: What are the key differences between the AD549JHZ and INA828ID?

A: The AD549JHZ is a general purpose amplifier, while the INA828ID is an instrumentation amplifier. The INA828ID has significantly higher input bias current (150 pA versus 0.15 pA). The INA828ID operates across an extended temperature range (-40°C to 125°C) compared to the AD549JHZ (0°C to 70°C). Both devices support the full 4.5 V to 36 V supply range and maintain 600 µA supply current.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The AD549JHZ, ADA4530-1ARZ, and INA828ID are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the impact of the ADA4530-1ARZ rail-to-rail output specification?

A: Rail-to-rail output capability allows the ADA4530-1ARZ output to swing closer to the positive and negative supply rails compared to the AD549JHZ. This specification is relevant for low-voltage applications and designs requiring maximum output voltage swing within constrained supply voltages.

Q: How does the Moisture Sensitivity Level differ between these devices?

A: The AD549JHZ and ADA4530-1ARZ both carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The INA828ID carries MSL 2 (1 Year), requiring storage in controlled humidity environments and limiting shelf life to one year from the date of manufacture if not stored in dry conditions.

Q: Which substitute part is appropriate for industrial temperature range applications?

A: Both the ADA4530-1ARZ and INA828ID operate across -40°C to 125°C, extending beyond the AD549JHZ range of 0°C to 70°C. Selection between these two depends on whether general purpose or instrumentation amplifier functionality is required for the specific application.
