LT1996ACMS#PBF Equivalent & Substitute Parts

Part Overview

The LT1996ACMS#PBF is a Programmable Gain Amplifier (PGA) integrated circuit manufactured by Analog Devices Inc. in a 10-MSOP surface mount package. This single-circuit, rail-to-rail operational amplifier is designed for applications requiring adjustable gain configurations with low input offset voltage and minimal input bias current. The device operates across a wide supply voltage range of 2.7 V to 36 V and maintains active product status with full RoHS3 compliance. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part number becomes unavailable or when alternative temperature grades or specifications are required.

Substitute Part Grouping Explanation

Substitution of the LT1996ACMS#PBF is determined by strict equivalence across all critical electrical and mechanical parameters. The primary substitution criterion is the base product number LT1996, which defines the core amplifier architecture and functional characteristics. Both the main part and substitute part share identical specifications for amplifier type (Programmable Gain), circuit count (1), output configuration (Rail-to-Rail), slew rate (0.12 V/µs), gain bandwidth product (560 kHz), -3dB bandwidth (38 kHz), input bias current (2.5 nA), supply current (130 µA), output current per channel (21 mA), and supply voltage range (2.7 V to 36 V).

The key differentiating parameter between the LT1996ACMS#PBF and its substitute is the voltage input offset specification. The main part (LT1996ACMS#PBF) specifies a maximum input offset voltage of 15 µV, while the substitute part (LT1996CMS#PBF) specifies 25 µV. This difference reflects a tighter offset voltage tolerance grade in the main part. Both parts operate within the identical temperature range (0°C to 70°C), utilize the same 10-MSOP surface mount package, and maintain equivalent packaging in tubes.

Substitution is valid when the application circuit can tolerate the relaxed input offset voltage specification of 25 µV. Both parts are manufactured by Analog Devices Inc., carry active product status, maintain ROHS3 compliance, and are classified as REACH Unaffected with identical ECCN and HTSUS codes.

Parameter Comparison

Engineering Selection Recommendations

Both the LT1996ACMS#PBF and LT1996CMS#PBF are active products manufactured by Analog Devices Inc. with full ROHS3 compliance and REACH Unaffected status. Selection between these parts is based on input offset voltage tolerance requirements and application-specific accuracy specifications.

The LT1996ACMS#PBF, with a 15 µV maximum input offset voltage, is suitable for applications requiring tighter DC accuracy and lower offset drift characteristics. This part number represents the higher-precision grade within the LT1996 family.

The LT1996CMS#PBF, with a 25 µV maximum input offset voltage, is suitable for applications where relaxed offset voltage tolerance is acceptable. This part offers equivalent electrical performance across all other parameters and identical mechanical compatibility.

Both parts maintain identical supply voltage ranges (2.7 V to 36 V), operating temperature ranges (0°C to 70°C), and package specifications (10-MSOP surface mount). Direct substitution is valid when circuit design margins accommodate the 10 µV difference in input offset voltage specification. Both parts carry MSL Level 1 (Unlimited) moisture sensitivity classification, indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the LT1996CMS#PBF be used as a direct replacement for the LT1996ACMS#PBF?

A: The LT1996CMS#PBF is electrically and mechanically compatible with the LT1996ACMS#PBF across all parameters except input offset voltage. The substitute part specifies 25 µV maximum offset versus 15 µV for the main part. Direct substitution is valid when the application circuit design tolerates this 10 µV difference in DC offset specification.

Q: What is the significance of the input offset voltage difference between these parts?

A: Input offset voltage determines the DC accuracy of the amplifier output when no signal is applied. The LT1996ACMS#PBF offers tighter offset voltage control (15 µV maximum), making it suitable for precision instrumentation and high-accuracy signal conditioning. The LT1996CMS#PBF (25 µV maximum) is suitable for general-purpose programmable gain applications where offset voltage is less critical to overall system performance.

Q: Are both parts available in the same package?

A: Yes. Both the LT1996ACMS#PBF and LT1996CMS#PBF are supplied in the 10-MSOP surface mount package with identical pin configuration, footprint, and mechanical dimensions (0.118" width, 3.00 mm). No PCB layout modifications are required for substitution.

Q: Do these parts have different supply voltage requirements?

A: No. Both parts operate across the identical supply voltage range of 2.7 V to 36 V. Supply voltage specifications, current consumption (130 µA), and output current capability (21 mA per channel) are identical between the main part and substitute.

Q: What is the operating temperature range for both parts?

A: Both the LT1996ACMS#PBF and LT1996CMS#PBF operate across the identical temperature range of 0°C to 70°C. No temperature-related performance differences exist between these parts.

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

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, MSL Level 1 (Unlimited), and identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications. Both parts maintain active product status with Analog Devices Inc.

Q: What are the key electrical parameters that remain identical between these parts?

A: The following parameters are identical: Slew Rate (0.12 V/µs), Gain Bandwidth Product (560 kHz), -3dB Bandwidth (38 kHz), Input Bias Current (2.5 nA), Supply Current (130 µA), Output Current per Channel (21 mA), and all supply voltage specifications. Only the input offset voltage specification differs.

Q: Can I use the LT1996ACMS#PBF in applications designed for the LT1996CMS#PBF?

A: Yes. The LT1996ACMS#PBF can be used in place of the LT1996CMS#PBF. The tighter input offset voltage specification (15 µV versus 25 µV) of the main part provides improved DC accuracy and is fully compatible with any circuit designed for the substitute part.
