TLV2432CD Equivalent & Substitute Parts

Part Overview

The TLV2432CD is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device features rail-to-rail output capability and operates across a 2.7V to 10V supply voltage range, making it suitable for low-power analog signal processing applications. The TLV2432CD is currently in Last Time Buy status, indicating discontinued production. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain reliability for ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV2432CD is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Number of Circuits: 2
• Output Type: Rail-to-Rail
• Amplifier Type: CMOS
• Operating Temperature Range: 0°C to 70°C
• Voltage - Supply Span: Minimum 2.7V, Maximum 10V

Substitute Parts Identified:

Group 1: Direct Packaging Equivalent

• TLV2432CDR (Texas Instruments) — Identical electrical specifications; differs only in packaging format (Cut Tape & Digi-Reel® versus Tube). Active product status provides long-term availability.

Group 2: Functional Equivalents with Enhanced Performance

• ALD2711ASAL (Advanced Linear Devices Inc.)
• ALD2711BSAL (Advanced Linear Devices Inc.)

Both ALD2711 variants meet all mandatory matching parameters. These devices exhibit superior electrical performance characteristics (higher slew rate, increased gain bandwidth product, lower input bias current) while maintaining compatibility with the 8-SOIC package footprint and supply voltage requirements.

Parameter Comparison

Engineering Selection Recommendations

TLV2432CDR Selection Rationale: The TLV2432CDR is the primary substitute for the TLV2432CD. Both devices are manufactured by Texas Instruments and share identical electrical specifications. The TLV2432CDR differs only in packaging format (Cut Tape & Digi-Reel® versus Tube). The TLV2432CDR maintains Active product status, ensuring continued availability and manufacturing support. This part is suitable for direct replacement in applications where the original TLV2432CD specifications are required without modification.

ALD2711ASAL and ALD2711BSAL Selection Rationale: The ALD2711 series (both ASAL and BSAL variants) are functional equivalents manufactured by Advanced Linear Devices Inc. These devices meet all mandatory compatibility parameters for 8-SOIC package footprint, dual-channel configuration, rail-to-rail output, and operating temperature range. Both variants maintain Active product status and ROHS3 compliance. The ALD2711 series exhibits enhanced performance characteristics including higher slew rate (1V/µs versus 0.25V/µs), increased gain bandwidth product (1MHz versus 550kHz), and lower input bias current (0.01pA versus 1pA). These devices are suitable for applications where improved dynamic performance is beneficial or required.

Compliance Considerations: All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status, ensuring regulatory alignment with the original TLV2432CD.

Frequently Asked Questions (FAQ)

Q: Can the TLV2432CDR be used as a direct replacement for the TLV2432CD?

A: Yes. The TLV2432CDR is electrically identical to the TLV2432CD. The only difference is packaging format: TLV2432CDR is supplied in Cut Tape & Digi-Reel® format, while TLV2432CD is supplied in Tube format. Both devices are pin-compatible, functionally equivalent, and suitable for direct PCB substitution.

Q: What are the key differences between the TLV2432CD and the ALD2711 series?

A: The ALD2711ASAL and ALD2711BSAL maintain identical package footprint (8-SOIC), pin count, and core functionality (dual-channel CMOS amplifier, rail-to-rail output). However, the ALD2711 series exhibits superior electrical performance: slew rate of 1V/µs (versus 0.25V/µs), gain bandwidth product of 1MHz (versus 550kHz), and input bias current of 0.01pA (versus 1pA). The ALD2711 series also features lower minimum supply voltage (2V versus 2.7V) and higher supply current consumption (200µA versus 100µA per channel).

Q: Are the ALD2711ASAL and ALD2711BSAL interchangeable with each other?

A: Both ALD2711ASAL and ALD2711BSAL share identical electrical specifications and package format. The distinction between ASAL and BSAL variants is not specified in the provided technical data. Consult Advanced Linear Devices Inc. documentation for variant-specific differences.

Q: What is the significance of the TLV2432CD being in Last Time Buy status?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of the TLV2432CD. Existing inventory will be depleted without replenishment. The TLV2432CDR (Active status) and ALD2711 series (Active status) provide long-term alternatives to ensure continued supply chain availability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The TLV2432CDR, ALD2711ASAL, and ALD2711BSAL are all ROHS3 compliant, matching the compliance status of the original TLV2432CD.

Q: Can the ALD2711 series be used in applications requiring the exact electrical specifications of the TLV2432CD?

A: The ALD2711 series meets all mandatory compatibility parameters (package, pin count, dual-channel configuration, rail-to-rail output, operating temperature range, supply voltage range). However, the ALD2711 series exhibits different electrical performance characteristics. Applications with strict requirements for slew rate (0.25V/µs), gain bandwidth product (550kHz), input bias current (1pA), or output current per channel (50mA) must evaluate whether the enhanced ALD2711 performance characteristics are acceptable or require design modification.

Q: What is the moisture sensitivity level for all substitute parts?

A: All substitute parts (TLV2432CDR, ALD2711ASAL, ALD2711BSAL) have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
