LT1192CS8#PBF Equivalent & Substitute Parts

Part Overview

The LT1192CS8#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 LT1192CS8#PBF delivers a slew rate of 450V/µs with a maximum output current of 50 mA per channel and operates across a dual supply voltage range of ±2.38V to ±8V or single supply of 4.75V to 16V. Due to its Last Time Buy status, identifying functionally compatible substitute components is essential for design continuity and long-term product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LT1192CS8#PBF is determined by compatibility across the following critical parameters:

Package and Mounting Compatibility: The substitute part must utilize the same 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure direct PCB footprint compatibility without layout modifications.

Electrical Performance Envelope: The substitute must operate within the voltage supply range requirements and deliver equivalent or superior output current capability. The LT1192CS8#PBF operates at 4.75V to 16V (single supply) or ±2.38V to ±8V (dual supply) with 50 mA maximum output current per channel.

Regulatory and Compliance Alignment: The substitute part must maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating to ensure compatibility with manufacturing processes and environmental regulations.

Circuit Configuration: The substitute must provide a single-circuit amplifier configuration matching the original device topology.

The LT1818CS8#PBF meets these substitution criteria while offering enhanced performance characteristics including higher slew rate (2500V/µs), increased gain bandwidth product (400 MHz), and lower supply current (9 mA), making it suitable for applications requiring improved dynamic performance within the same package footprint.

Parameter Comparison

Engineering Selection Recommendations

The LT1818CS8#PBF is the manufacturer-recommended substitute for the LT1192CS8#PBF. Both devices share identical package specifications (8-SOIC surface mount) and maintain full regulatory compliance with ROHS3 and REACH requirements. The LT1818CS8#PBF carries Active product status, ensuring continued availability and long-term supply security compared to the Last Time Buy status of the LT1192CS8#PBF.

The LT1818CS8#PBF provides enhanced electrical performance with a slew rate of 2500V/µs (compared to 450V/µs) and increased output current capability of 70 mA per channel (compared to 50 mA). The substitute operates at a lower supply current of 9 mA versus 32 mA, reducing power consumption in battery-powered or thermally constrained applications. The minimum supply voltage requirement of 2.5V for the LT1818CS8#PBF extends operational flexibility in low-voltage applications.

Both devices maintain MSL 1 (Unlimited) moisture sensitivity ratings, eliminating concerns regarding moisture-related reliability differences during manufacturing and storage.

Frequently Asked Questions (FAQ)

Q: Can the LT1818CS8#PBF be used as a direct replacement for the LT1192CS8#PBF without PCB modifications?

A: Yes. Both devices utilize the identical 8-SOIC (0.154", 3.90mm Width) surface mount package, enabling direct footprint compatibility. No PCB layout changes are required for physical placement.

Q: What are the key electrical differences between these two amplifiers?

A: The LT1818CS8#PBF offers superior dynamic performance with a slew rate of 2500V/µs compared to the LT1192CS8#PBF at 450V/µs. The LT1818CS8#PBF also provides higher output current (70 mA versus 50 mA) and operates at lower supply current (9 mA versus 32 mA). The LT1818CS8#PBF includes a gain bandwidth product specification of 400 MHz and input offset voltage specification of 200 µV.

Q: Are there supply voltage compatibility concerns when substituting the LT1818CS8#PBF?

A: The LT1818CS8#PBF operates across a supply voltage range of 2.5V to 12.6V, which encompasses the LT1192CS8#PBF operating range of 4.75V to 16V (single supply) or ±2.38V to ±8V (dual supply). The LT1818CS8#PBF minimum voltage of 2.5V is lower than the LT1192CS8#PBF minimum of 4.75V, providing extended low-voltage operation capability. Circuit designs operating within the LT1192CS8#PBF voltage specifications will function with the LT1818CS8#PBF.

Q: Do both devices maintain equivalent regulatory compliance?

A: Yes. Both the LT1192CS8#PBF and LT1818CS8#PBF are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. No compliance-related design changes are necessary when substituting between these devices.

Q: Why is the LT1192CS8#PBF designated as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has discontinued production of the LT1192CS8#PBF and existing inventory represents the final availability. The LT1818CS8#PBF, with Active product status, ensures continued supply and manufacturing support for new designs and production requirements.

Q: What is the operating temperature range for the LT1818CS8#PBF?

A: The LT1818CS8#PBF operates across a temperature range of 0°C to 70°C.
