LT1190CS8#PBF Equivalent & Substitute Parts

Part Overview

The LT1190CS8#PBF is a general-purpose video amplifier integrated circuit manufactured by Analog Devices Inc. in an 8-SOIC surface mount package. This device is classified as a Last Time Buy product, indicating that it is no longer in active production and existing inventory represents the final availability from the manufacturer. The LT1190CS8#PBF is designed for general-purpose amplification applications requiring high slew rate performance in a compact form factor.

Due to the Last Time Buy status of the LT1190CS8#PBF, identification of functionally equivalent substitute components is necessary for design continuity and long-term supply chain planning. Substitute parts must maintain compatibility with existing circuit designs while meeting the electrical and mechanical requirements of the application.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LT1190CS8#PBF is determined by the following critical parameters:

Package Compatibility: The substitute part must utilize the same 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure mechanical and electrical compatibility with existing printed circuit board layouts and assembly processes.

Electrical Performance: The substitute must support the required voltage supply range and deliver equivalent or superior output current capability. The slew rate specification defines the maximum rate of voltage change and is a primary performance criterion for video amplifier applications.

Supply Current: The substitute should not exceed the supply current requirements of the original design to maintain power budget constraints.

Regulatory Compliance: The substitute must maintain ROHS3 compliance and REACH Unaffected status to satisfy environmental and regulatory requirements.

Circuit Count: The substitute must provide a single-circuit configuration to match the original device topology.

The LT1360CS8#PBF meets these substitution criteria through identical packaging, superior slew rate performance, compatible voltage supply specifications, and equivalent regulatory compliance status.

Engineering Selection Recommendations

The LT1360CS8#PBF is a direct substitute for the LT1190CS8#PBF based on the following engineering criteria:

Package Compatibility: Both devices are housed in the identical 8-SOIC surface mount package, ensuring pin-for-pin compatibility and direct replacement capability on existing circuit boards without layout modifications.

Regulatory and Compliance Status: The LT1360CS8#PBF maintains ROHS3 compliance and REACH Unaffected status, satisfying the same environmental and regulatory requirements as the original device. Both components carry Moisture Sensitivity Level 1 (Unlimited), indicating equivalent handling and storage requirements.

Production Status: The LT1360CS8#PBF is classified as an Active product with current manufacturing availability, providing long-term supply security compared to the Last Time Buy status of the LT1190CS8#PBF. This substitution addresses supply continuity concerns for ongoing production and future design iterations.

Electrical Performance: The LT1360CS8#PBF delivers enhanced electrical performance characteristics, including higher slew rate (800V/µs versus 450V/µs) and lower supply current consumption (4 mA versus 32 mA). These improvements provide design margin and reduced power dissipation in applications where the original device specifications are met or exceeded.

Application Compatibility: For applications requiring the general-purpose amplification capabilities of the LT1190CS8#PBF, the LT1360CS8#PBF provides equivalent or superior functionality within the same physical and electrical constraints.

Frequently Asked Questions (FAQ)

Q: Can the LT1360CS8#PBF be used as a direct replacement for the LT1190CS8#PBF in existing designs?

A: Yes. Both devices utilize the identical 8-SOIC surface mount package with the same pinout and electrical interface. The LT1360CS8#PBF can be substituted directly without circuit board layout modifications or design changes.

Q: What are the key differences between the LT1190CS8#PBF and LT1360CS8#PBF?

A: The primary differences are slew rate (800V/µs for LT1360 versus 450V/µs for LT1190), supply current (4 mA for LT1360 versus 32 mA for LT1190), and product status (Active for LT1360 versus Last Time Buy for LT1190). The LT1360CS8#PBF also supports a wider voltage supply range (5V ~ 30V versus 4.75V ~ 16V, ±2.38V ~ 8V).

Q: Does the lower output current of the LT1360CS8#PBF (34 mA versus 50 mA) affect substitution suitability?

A: Output current capability must be evaluated against specific application requirements. If the original design requires output current exceeding 34 mA, the LT1360CS8#PBF may not be suitable. Applications requiring 34 mA or less output current are compatible with the substitute device.

Q: Are there any compliance or regulatory differences between these devices?

A: No. Both the LT1190CS8#PBF and LT1360CS8#PBF maintain identical ROHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited) ratings. No additional compliance considerations are introduced by substitution.

Q: Why is the LT1190CS8#PBF designated as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has discontinued active production of this device. Existing inventory represents the final availability. The LT1360CS8#PBF, classified as Active, ensures continued supply availability for new designs and production requirements.

Q: What is the voltage supply range compatibility between these devices?

A: The LT1190CS8#PBF operates at 4.75V ~ 16V (single supply) or ±2.38V ~ 8V (dual supply). The LT1360CS8#PBF operates at 5V ~ 30V. Designs operating within the LT1190 voltage range are fully compatible with the LT1360. Designs utilizing the extended voltage range of the LT1360 (above 16V single supply or ±8V dual supply) require verification that the original design does not depend on voltage-specific performance characteristics.

Q: Is the higher slew rate of the LT1360CS8#PBF (800V/µs) a concern for existing designs?

A: Higher slew rate is generally beneficial for signal fidelity and transient response. Existing designs specified for 450V/µs slew rate will operate correctly with the higher slew rate of the LT1360CS8#PBF. No design modifications are required to accommodate this performance improvement.
