LT6200CS8 Equivalent & Substitute Parts

Part Overview

The LT6200CS8 is an active buffer amplifier integrated circuit manufactured by Analog Devices Inc., designed for rail-to-rail signal conditioning applications. This single-circuit, 8-SO surface mount device operates across a 2.5 V to 12.6 V supply range and delivers 90 mA output current per channel. The device is classified as Active in product status and maintains full RoHS3 compliance with MSL Level 1 moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this buffer amplifier category. Substitution becomes necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives meeting identical or superior performance criteria.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LT6200CS8 are qualified based on the following substitution criteria:

Direct Substitutes maintain identical electrical specifications across all critical parameters: slew rate (50 V/µs), gain bandwidth product (165 MHz), input bias current (23 µA), input offset voltage (2.5 mV), supply current (20 mA), output current per channel (90 mA), supply voltage range (2.5 V to 12.6 V), and operating temperature range (0°C to 70°C). These parts share the same 8-SOIC package footprint and surface mount mounting type.

Similar Substitutes are qualified when they operate within the same package family (8-SOIC), maintain surface mount compatibility, and preserve rail-to-rail output capability. These parts may exhibit enhanced performance characteristics such as higher slew rates, increased gain bandwidth products, or extended operating temperature ranges, provided they do not introduce incompatibilities with the target application circuit topology.

All substitute relationships are constrained by the following mandatory parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Number of Circuits: 1
• RoHS3 Compliance
• MSL Level 1 Rating

Parameter Comparison

Engineering Selection Recommendations

LT6200CS8#PBF is a direct functional equivalent to the LT6200CS8, differing only in packaging format (Tube versus standard packaging). Both devices are manufactured by Analog Devices Inc., maintain identical electrical specifications, and carry Active product status with full RoHS3 compliance. Selection between these two part numbers is determined by procurement requirements and assembly process compatibility. The LT6200CS8#PBF offers higher inventory availability (1218 Pcs versus 955 Pcs) and may be preferred when tube packaging aligns with manufacturing workflows.

THS4504D is a qualified substitute from Texas Instruments that maintains 8-SOIC package compatibility and surface mount mounting type. This device exhibits enhanced performance characteristics including significantly higher slew rate (1800 V/µs versus 50 V/µs), increased gain bandwidth product (210 MHz versus 165 MHz), lower input bias current (4 µA versus 23 µA), and extended operating temperature range (-40°C to 85°C versus 0°C to 70°C). However, the THS4504D operates as a differential amplifier with differential output type, whereas the LT6200CS8 is configured as a buffer with rail-to-rail output. This functional difference requires circuit topology evaluation to confirm compatibility. The THS4504D requires minimum supply voltage of 4.5 V, which exceeds the LT6200CS8 minimum of 2.5 V. All three devices maintain RoHS3 compliance and MSL Level 1 ratings.

Frequently Asked Questions (FAQ)

Q: Can LT6200CS8#PBF be used as a direct replacement for LT6200CS8?

A: Yes. The LT6200CS8#PBF is electrically and functionally identical to the LT6200CS8. The only difference is packaging format: LT6200CS8#PBF is supplied in Tube packaging while LT6200CS8 uses standard packaging. Both devices share identical electrical specifications, pin configurations, and performance characteristics. Selection depends on assembly process requirements and packaging compatibility with your manufacturing equipment.

Q: Is THS4504D a direct substitute for LT6200CS8?

A: THS4504D is a qualified alternative that shares the same 8-SOIC package footprint and surface mount compatibility. However, it is not a direct functional equivalent. The THS4504D is configured as a differential amplifier with differential output, whereas the LT6200CS8 is a buffer amplifier with rail-to-rail output. Circuit topology and signal conditioning requirements must be evaluated to confirm compatibility. The THS4504D offers superior performance in slew rate (1800 V/µs), gain bandwidth product (210 MHz), and operating temperature range (-40°C to 85°C), but requires minimum supply voltage of 4.5 V compared to the LT6200CS8 minimum of 2.5 V.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: (1) Package / Case compatibility (8-SOIC 0.154" width), (2) Mounting Type (Surface Mount), (3) Number of Circuits (1), (4) RoHS3 Compliance status, and (5) MSL Level 1 rating. Electrical parameters including slew rate, gain bandwidth product, supply voltage range, and output type must be evaluated against application requirements to confirm functional compatibility.

Q: Can I use THS4504D in a circuit designed for LT6200CS8?

A: Circuit compatibility requires detailed evaluation of the application topology. While both devices share the 8-SOIC package and surface mount compatibility, the THS4504D differential output configuration differs from the LT6200CS8 rail-to-rail buffer output. Applications requiring rail-to-rail buffering may not be compatible with differential output architecture. Additionally, the THS4504D minimum supply voltage of 4.5 V may not be suitable for applications operating at the LT6200CS8 minimum of 2.5 V. Consult application schematics and signal conditioning requirements before substitution.

Q: What is the difference between the LT6200CS8 and LT6200CS8#PBF part numbers?

A: The LT6200CS8 and LT6200CS8#PBF are identical devices from Analog Devices Inc. The "#PBF" suffix indicates Tube packaging format, whereas the base part number uses standard packaging. Electrical specifications, pin configurations, performance characteristics, and compliance ratings are identical. The choice between these part numbers is determined by procurement preferences and assembly process compatibility with Tube or standard packaging formats.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (LT6200CS8#PBF and THS4504D) maintain ROHS3 Compliant status, matching the RoHS3 compliance of the primary LT6200CS8 device. All parts also carry MSL Level 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.
