ADA4807-4ARUZ Equivalent & Substitute Parts

Part Overview

The ADA4807-4ARUZ is a quad-channel voltage feedback operational amplifier manufactured by Analog Devices Inc., designed for applications requiring high-speed signal conditioning and amplification. This surface-mount integrated circuit features rail-to-rail output capability, making it suitable for low-voltage supply applications. The device is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when original inventory is unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications permit operation within the electrical and mechanical parameters of equivalent devices.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADA4807-4ARUZ is determined by electrical and mechanical compatibility within the following criteria:

Electrical Compatibility Parameters:

• Number of circuits: Must be 4 channels
• Amplifier topology: Voltage feedback or J-FET input types acceptable
• Output configuration: Rail-to-rail or standard output types acceptable
• Supply voltage range: Substitute must operate within or encompass the 2.7V to 11V span
• Operating temperature: Substitute must support -40°C minimum; upper limit may vary
• Surface-mount packaging: Required for PCB assembly compatibility

Mechanical Compatibility Parameters:

• Package type: 14-pin configurations (TSSOP, SOIC, or equivalent 14-pin surface-mount packages)
• Pin count: 14 pins mandatory
• Package width: Acceptable within standard surface-mount footprint tolerances

Compliance Requirements:

• RoHS3 compliance required
• Moisture sensitivity level 1 acceptable
• Active product status preferred

The TL074IDR from Texas Instruments meets the core substitution criteria of quad-channel configuration, 14-pin surface-mount packaging, and RoHS3 compliance, though with differing electrical performance characteristics in slew rate, bandwidth, and supply voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

ADA4807-4ARUZ Selection Criteria:

• Applications requiring high slew rate performance (250V/µs) and wide bandwidth (180 MHz)
• Low-voltage supply designs operating between 2.7V and 11V
• Extended temperature operation to 125°C
• Rail-to-rail output requirements
• 14-TSSOP package footprint compatibility
• RoHS3 and unlimited MSL compliance mandatory

TL074IDR Selection Criteria:

• Applications where J-FET input characteristics are acceptable or preferred
• Designs with higher supply voltage requirements (10V to 30V range)
• Lower input bias current requirements (65 pA vs. 1.2 µA)
• Standard temperature operation to 85°C maximum
• 14-SOIC package footprint compatibility
• RoHS3 and unlimited MSL compliance mandatory

Substitution Feasibility: The TL074IDR functions as a substitute only in applications where the electrical performance differences do not impact circuit operation. The reduced slew rate (13V/µs vs. 250V/µs), lower bandwidth (5.25 MHz vs. 180 MHz), and narrower supply voltage range (10V to 30V vs. 2.7V to 11V) represent significant deviations. Package format differs (14-SOIC vs. 14-TSSOP), requiring PCB layout modification. Substitution is valid only when application specifications explicitly permit these parameter variations and when PCB footprint redesign is feasible.

Frequently Asked Questions (FAQ)

Q: Can the TL074IDR directly replace the ADA4807-4ARUZ in all applications?

A: No. While both devices are quad-channel, 14-pin surface-mount operational amplifiers with RoHS3 compliance, the TL074IDR exhibits significantly different electrical performance. The ADA4807-4ARUZ operates at 250V/µs slew rate with 180 MHz bandwidth, while the TL074IDR operates at 13V/µs with 5.25 MHz bandwidth. Supply voltage ranges differ (2.7V–11V vs. 10V–30V). Substitution is valid only when application specifications explicitly permit these performance reductions and when the circuit design does not depend on the higher speed characteristics of the ADA4807-4ARUZ.

Q: What are the package compatibility considerations?

A: The ADA4807-4ARUZ uses 14-TSSOP packaging (0.173" width, 4.40mm), while the TL074IDR uses 14-SOIC packaging (0.154" width, 3.90mm). Although both are 14-pin surface-mount packages, the footprints are not identical. PCB layout modification is required for substitution. Pin assignments must be verified against device datasheets to ensure correct signal routing.

Q: Are there temperature range limitations when substituting?

A: Yes. The ADA4807-4ARUZ operates from -40°C to 125°C, while the TL074IDR operates from -40°C to 85°C. If the application requires operation above 85°C, the TL074IDR is not suitable. Conversely, if the application operates only within the 0°C to 70°C range, both devices are acceptable.

Q: What is the significance of the input bias current difference?

A: The ADA4807-4ARUZ has 1.2 µA input bias current, while the TL074IDR has 65 pA input bias current. The TL074IDR's J-FET input stage provides significantly lower bias current. In high-impedance input circuits, this difference affects DC operating point and offset voltage performance. Applications with high-impedance sources may benefit from the TL074IDR's lower bias current, while applications with low-impedance sources are unaffected.

Q: Can the ADA4807-4ARUZ operate at the TL074IDR's supply voltage range?

A: The ADA4807-4ARUZ is specified for 2.7V to 11V supply operation. The TL074IDR requires minimum 10V supply. The ADA4807-4ARUZ can operate at 10V and 11V, overlapping with the TL074IDR's lower range. However, the ADA4807-4ARUZ cannot operate at the TL074IDR's maximum 30V supply. Substitution in the 10V–11V range is electrically feasible but requires verification of all other circuit parameters.

Q: What compliance certifications apply to both devices?

A: Both the ADA4807-4ARUZ and TL074IDR are RoHS3 compliant, carry moisture sensitivity level 1 (unlimited), and are classified as REACH unaffected. Both are assigned ECCN EAR99 and HTSUS 8542.33.0001 for export and tariff purposes. Compliance status is equivalent between the two devices.

Q: Is the ADA4807-4ARUZ available in alternative packages?

A: The provided data specifies the ADA4807-4ARUZ in 14-TSSOP packaging only. The base product number ADA4807 may be available in alternative package configurations from the manufacturer, but such variants are not included in this substitution reference.
