Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the XR8052ASO8 is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 8-SOIC surface mount package with 0.154" (3.90mm) width to ensure direct PCB footprint compatibility without layout modifications.

Functional Architecture: Substitute devices must feature voltage feedback amplifier topology with dual circuits (2 channels) and rail-to-rail output capability to maintain circuit behavior and signal path integrity.

Electrical Operating Range: Substitute parts must support the minimum supply voltage of 2.7V and accommodate the maximum supply voltage of 12.6V. The operating temperature range of -40°C to 125°C must be maintained.

Performance Envelope: While substitute parts may exhibit different slew rates, gain bandwidth products, and bandwidth characteristics, they must remain within acceptable ranges for typical voltage feedback amplifier applications. Input bias current, input offset voltage, supply current, and output current specifications define the electrical operating envelope.

The LMH6619QMAKE/NOPB and LMH6619QMAKX/NOPB from Texas Instruments satisfy these substitution criteria. Both devices maintain identical package, circuit count, output type, and operating temperature specifications. These parts are active products with automotive-grade qualification (AEC-Q100), providing enhanced lifecycle support compared to the obsolete XR8052ASO8.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The XR8052ASO8 carries obsolete status, indicating discontinued manufacturing and restricted availability. The LMH6619QMAKE/NOPB and LMH6619QMAKX/NOPB are active products from Texas Instruments, ensuring ongoing production, extended lead times, and manufacturer support.

Compliance and Qualification: Both Texas Instruments substitutes hold AEC-Q100 automotive qualification, providing enhanced reliability documentation and manufacturing process controls. The LMH6619 series maintains ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Packaging and Footprint: All three devices utilize identical 8-SOIC surface mount packaging, enabling direct PCB footprint compatibility without layout redesign or assembly process modifications.

Electrical Performance Trade-offs: The LMH6619 substitutes exhibit lower slew rate (57V/µs versus 190V/µs) and reduced gain bandwidth product (140 MHz versus 260 MHz). These differences require circuit-level evaluation for applications with stringent bandwidth or transient response requirements. Supply current is reduced by 50% (1.3mA versus 2.6mA), and output current per channel is reduced to 35mA versus 100mA.

Supply Voltage Range: The LMH6619 series supports minimum supply voltage of 2.7V, matching the XR8052ASO8. Maximum supply voltage is 11V for the LMH6619 devices, compared to 12.6V for the original part. Applications operating above 11V require design verification.

Selection Path: For new designs and production requiring extended lifecycle support, the LMH6619QMAKE/NOPB or LMH6619QMAKX/NOPB are the recommended substitutes. Both variants are functionally equivalent; packaging format (Tape & Reel) differs only in supply configuration.

Frequently Asked Questions (FAQ)

Q: Can the LMH6619QMAKE/NOPB and LMH6619QMAKX/NOPB be used interchangeably with the XR8052ASO8?

A: Both LMH6619 variants maintain identical electrical specifications and package footprint compatibility with the XR8052ASO8. Direct substitution is possible from a PCB assembly perspective. Circuit-level performance differences in slew rate and bandwidth require application-specific evaluation.

Q: What is the primary difference between LMH6619QMAKE/NOPB and LMH6619QMAKX/NOPB?

A: Both parts are functionally identical with matching electrical specifications. The difference lies in packaging format: QMAKE/NOPB is supplied in Tape & Reel format, while QMAKX/NOPB is also supplied in Tape & Reel format. Consult Texas Instruments documentation for specific packaging configuration details.

Q: Will the reduced slew rate of the LMH6619 (57V/µs) affect my circuit?

A: The LMH6619 slew rate of 57V/µs is lower than the XR8052ASO8 specification of 190V/µs. Applications requiring high-speed transient response or driving capacitive loads at maximum frequency may experience performance degradation. Circuit simulation or bench testing is necessary to confirm suitability for specific signal conditions.

Q: Are the LMH6619 devices suitable for automotive applications?

A: Yes. Both LMH6619QMAKE/NOPB and LMH6619QMAKX/NOPB carry AEC-Q100 automotive qualification, meeting automotive industry reliability and manufacturing standards.

Q: What is the maximum supply voltage for the LMH6619 substitutes?

A: The LMH6619 series supports maximum supply voltage of 11V. The XR8052ASO8 supports 12.6V. Applications requiring operation above 11V are not compatible with the LMH6619 substitutes without circuit redesign.

Q: Are the 8-SOIC packages identical between all three devices?

A: Yes. All three devices use 8-SOIC surface mount packages with 0.154" (3.90mm) width, ensuring identical PCB footprints and assembly compatibility without layout modifications.

Q: What is the moisture sensitivity level for these devices?

A: All three devices carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: How do the input offset voltage specifications compare?

A: The XR8052ASO8 specifies 500µV input offset voltage, while the LMH6619 devices specify 100µV. The LMH6619 substitutes provide superior input offset voltage performance, reducing DC error in precision applications.
