LT1996ACDD#PBF Equivalent & Substitute Parts

Part Overview

The LT1996ACDD#PBF is a Programmable Gain Amplifier (PGA) manufactured by Analog Devices Inc., designed for precision signal conditioning applications. This single-circuit, rail-to-rail operational amplifier is housed in a 10-DFN (3x3) surface mount package with an exposed pad. The device is currently in Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across critical parameters. The LT1996ACDD#PBF has one parametric equivalent available, though product status and compliance differences must be evaluated for application suitability.

Substitute Part Grouping Explanation

Substitution eligibility for the LT1996ACDD#PBF is determined by equivalence across the following critical parameters:

Electrical Performance Criteria:

• Amplifier Type: Programmable Gain
• Number of Circuits: 1
• Slew Rate: 0.12 V/µs
• Gain Bandwidth Product: 560 kHz
• -3dB Bandwidth: 38 kHz
• Current - Input Bias: 2.5 nA
• Current - Supply: 130 µA
• Current - Output / Channel: 21 mA
• Voltage - Supply Span: 2.7 V to 36 V
• Operating Temperature Range: 0°C to 70°C

Mechanical Compatibility Criteria:

• Package / Case: 10-WFDFN Exposed Pad
• Supplier Device Package: 10-DFN (3x3)
• Mounting Type: Surface Mount

The LT1996CDD#PBF meets all electrical performance and mechanical compatibility requirements. Variations in Voltage - Input Offset (25 µV vs. 15 µV) and Output Type specification remain within acceptable substitution parameters for this device category.

Engineering Selection Recommendations

Primary Selection: LT1996ACDD#PBF

The LT1996ACDD#PBF is the recommended choice for new designs and production applications. This device carries Active product status, ensuring long-term availability and manufacturer support. Full RoHS3 compliance and REACH unaffected status satisfy regulatory requirements for commercial and industrial applications. The device is supplied in tube packaging, appropriate for automated assembly processes.

Substitute Selection: LT1996CDD#PBF

The LT1996CDD#PBF is electrically equivalent and mechanically compatible but carries Obsolete product status. This device is RoHS non-compliant and has undefined REACH status. Substitution is limited to legacy system maintenance, repair, or applications where regulatory compliance is not required. The higher input offset voltage (25 µV vs. 15 µV) may impact precision-critical applications. Bulk packaging indicates suitability for manual assembly or small-volume operations only.

Compliance Considerations:

Applications subject to RoHS3 or REACH regulations must use the LT1996ACDD#PBF. The LT1996CDD#PBF is restricted to non-regulated environments or legacy system support where compliance exemptions apply.

Frequently Asked Questions (FAQ)

Q: Can the LT1996CDD#PBF replace the LT1996ACDD#PBF in new production?

A: No. The LT1996CDD#PBF is Obsolete and RoHS non-compliant. New production designs must use the LT1996ACDD#PBF, which is Active and RoHS3 compliant.

Q: Are the packages physically identical?

A: Yes. Both devices use the 10-WFDFN Exposed Pad package with 10-DFN (3x3) dimensions. PCB footprints and reflow profiles are identical. Surface mount assembly processes are compatible.

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

A: The LT1996ACDD#PBF specifies 15 µV input offset, while the LT1996CDD#PBF specifies 25 µV. For precision signal conditioning applications requiring offset trimming or calibration, this 10 µV difference may require circuit adjustment. For general-purpose gain applications, this variation is typically negligible.

Q: Can I use the LT1996CDD#PBF in a regulated industry application?

A: No. RoHS non-compliance and undefined REACH status disqualify the LT1996CDD#PBF from regulated industries including medical devices, automotive, and consumer electronics subject to environmental directives.

Q: What is the difference between Tube and Bulk packaging?

A: Tube packaging contains components in a continuous plastic tube, suitable for automated pick-and-place assembly. Bulk packaging contains loose components, requiring manual handling and reel preparation. Tube packaging is standard for high-volume production; bulk packaging is used for repair stock or low-volume assembly.

Q: Are there any electrical performance differences that affect circuit design?

A: All critical electrical parameters are equivalent: slew rate, gain bandwidth product, supply current, output current, and supply voltage range are identical. The input offset voltage variation does not affect circuit topology or component selection.

Q: What is the base product number?

A: The base product number is LT1996. The suffix designations (A, C) indicate temperature grade and performance binning. The suffix #PBF indicates lead-free, RoHS-compliant packaging.
