Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8007AR is determined by alignment across critical electrical and mechanical parameters. The primary substitution criteria are:

Direct Substitutes (Identical Topology & Performance): Parts maintaining current feedback amplifier topology with matching slew rate (1000V/µs), bandwidth (650 MHz), and 8-SOIC package form factor qualify as direct substitutes. These parts preserve circuit behavior and require no design modification.

Similar Substitutes (Different Topology or Performance Trade-offs): Parts with different amplifier topologies (voltage feedback, J-FET, general purpose) or reduced performance specifications (lower slew rate, reduced bandwidth) are classified as similar substitutes. These parts may require circuit design evaluation and are suitable only when performance requirements permit trade-offs.

Package Compatibility: All substitute parts must maintain surface mount configuration. Package variants (SOT-23-5, 14-DIP) introduce mechanical incompatibility and require PCB redesign.

Supply Voltage Compatibility: Substitute parts must support the 5V to 12V supply span of the original design or operate within a compatible subset of this range.

Engineering Selection Recommendations

AD8007ARZ (Direct Substitute - Recommended for Pin-Compatible Replacement)

The AD8007ARZ is the primary substitute for the obsolete AD8007AR. Both parts are manufactured by Analog Devices Inc. and share identical electrical specifications: 1000V/µs slew rate, 650 MHz bandwidth, current feedback topology, and 8-SOIC package configuration. The AD8007ARZ maintains active product status with ROHS3 compliance and REACH unaffected certification. This part requires no circuit design modification and provides direct functional equivalence. Packaging differs only in format (tube versus unspecified for the original), which does not affect electrical performance.

LMH6642MA/NOPB (Similar Substitute - Voltage Feedback Alternative)

The LMH6642MA/NOPB from Texas Instruments operates as a voltage feedback amplifier with rail-to-rail output capability. This part maintains 8-SOIC package compatibility and operates within the 5V to 12V supply range. Performance trade-offs include reduced slew rate (135V/µs versus 1000V/µs) and reduced bandwidth (130 MHz versus 650 MHz). The LMH6642MA/NOPB is suitable for applications where current feedback topology is not required and lower slew rate performance is acceptable. ROHS3 compliance and REACH unaffected status are confirmed.

MAX4452EUK+T (Similar Substitute - Low-Power Rail-to-Rail Alternative)

The MAX4452EUK+T from Analog Devices/Maxim Integrated is a voltage feedback amplifier in SOT-23-5 package. This part introduces package incompatibility (SOT-23-5 versus 8-SOIC) requiring PCB redesign. Supply voltage range is restricted to 2.7V to 5.25V, limiting compatibility with designs requiring 12V operation. Slew rate (95V/µs) and bandwidth (200 MHz) are significantly reduced. This substitute is applicable only when package change is acceptable and supply voltage requirements permit the 5.25V maximum limit.

OPA827AID (Similar Substitute - J-FET High-Impedance Alternative)

The OPA827AID from Texas Instruments is a J-FET amplifier with 8-SOIC package compatibility. This part offers extended operating temperature range (-40°C to 125°C) and extremely low input bias current (15 pA). Slew rate (28V/µs) and bandwidth (22 MHz gain-bandwidth product) are substantially reduced compared to the AD8007AR. Supply voltage range extends to 36V maximum. This substitute is suitable for applications prioritizing input impedance and temperature performance over bandwidth and slew rate. ROHS3 compliance is confirmed.

TLE2027ID (Similar Substitute - General Purpose Low-Noise Alternative)

The TLE2027ID from Texas Instruments is a general purpose amplifier in 8-SOIC package with Excalibur™ series designation. This part provides extremely low input offset voltage (20 µV) and low input bias current (15 nA). Slew rate (2.8V/µs) and bandwidth (13 MHz gain-bandwidth product) are substantially reduced. Supply voltage range extends to 38V maximum. This substitute is applicable for low-noise, low-speed applications where the AD8007AR's high-speed performance is not required. ROHS3 compliance is confirmed.

Frequently Asked Questions (FAQ)

Q: Can AD8007ARZ be used as a direct replacement for AD8007AR without circuit modification?

A: Yes. The AD8007ARZ is electrically and functionally identical to the AD8007AR. Both parts share current feedback topology, 1000V/µs slew rate, 650 MHz bandwidth, and 8-SOIC package configuration. No circuit design changes are required for substitution.

Q: What is the primary difference between the AD8007AR and AD8007ARZ?

A: The AD8007ARZ is the active production variant of the AD8007AR. The original AD8007AR is classified as obsolete. Both parts maintain identical electrical specifications and package form factor. The AD8007ARZ includes ROHS3 compliance certification.

Q: Can voltage feedback amplifiers like the LMH6642MA/NOPB replace the current feedback AD8007AR?

A: Voltage feedback amplifiers can replace the AD8007AR only when application requirements permit reduced slew rate (135V/µs versus 1000V/µs) and reduced bandwidth (130 MHz versus 650 MHz). Current feedback topology provides superior closed-loop bandwidth characteristics; voltage feedback substitutes are suitable for lower-speed applications. Circuit design evaluation is required.

Q: Is the MAX4452EUK+T package compatible with AD8007AR PCB layouts?

A: No. The MAX4452EUK+T uses SOT-23-5 package while the AD8007AR uses 8-SOIC package. These packages have different pin counts, spacing, and footprints. PCB redesign is required for substitution. Additionally, the MAX4452EUK+T supply voltage maximum is limited to 5.25V, restricting compatibility with 12V supply designs.

Q: What are the key performance trade-offs when substituting with J-FET amplifiers like OPA827AID?

A: J-FET amplifiers offer extremely low input bias current (15 pA versus 4 µA) and extended temperature range. Trade-offs include significantly reduced slew rate (28V/µs versus 1000V/µs) and reduced bandwidth (22 MHz gain-bandwidth product versus 650 MHz). J-FET substitutes are suitable for high-impedance input applications where speed is not critical.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed (AD8007ARZ, LMH6642MA/NOPB, MAX4452EUK+T, OPA827AID, TLE2027ID) are confirmed ROHS3 compliant. The original AD8007AR does not specify RoHS status.

Q: What is the moisture sensitivity level (MSL) difference between AD8007AR and OPA827AID?

A: The AD8007AR and most substitutes (AD8007ARZ, LMH6642MA/NOPB, MAX4452EUK+T, TLE2027ID) have MSL 1 (Unlimited). The OPA827AID has MSL 2 (1 Year), requiring more stringent moisture control during storage and handling. MSL 2 components must be baked before reflow soldering if storage exceeds one year.

Q: Can the TLE2027ID replace the AD8007AR in high-speed signal conditioning applications?

A: No. The TLE2027ID is a general purpose amplifier with 2.8V/µs slew rate and 13 MHz gain-bandwidth product, substantially lower than the AD8007AR's 1000V/µs slew rate and 650 MHz bandwidth. The TLE2027ID is suitable only for low-speed, low-noise applications where high-speed performance is not required.

Q: What supply voltage range must be verified when selecting a substitute?

A: The AD8007AR operates with 5V to 12V supply span. Substitutes must support this range or a compatible subset. The MAX4452EUK+T is limited to 2.7V to 5.25V maximum, incompatible with 12V designs. The OPA827AID and TLE2027ID support extended ranges (8V to 36V and 8V to 38V respectively) and are compatible with the original supply requirements.
