LM13700MX Equivalent & Substitute Parts

Part Overview

The LM13700MX is a transconductance amplifier integrated circuit manufactured by Texas Instruments, featuring two independent circuits with push-pull output configuration in a 16-SOIC surface mount package. This device is classified as "Not For New Designs," indicating it has been superseded in the product lifecycle. The transconductance amplifier topology makes it suitable for applications requiring voltage-to-current conversion with high linearity and low distortion characteristics.

Due to its obsolescence status, identifying functionally equivalent substitute parts is essential for design continuity, maintenance, and legacy system support. The substitute identified maintains identical electrical specifications and mechanical compatibility, ensuring direct replacement capability.

Substitute Part Grouping Explanation

Substitution of the LM13700MX is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Equivalence Requirements:

• Identical amplifier type (Transconductance)
• Identical number of circuits (2)
• Identical output configuration (Push-Pull)
• Matching slew rate (50 V/µs)
• Matching gain bandwidth product (2 MHz)
• Matching input bias current (400 nA)
• Matching input offset voltage (300 µV)
• Matching supply current specifications (2.6 mA per channel)
• Matching output current per channel (500 µA)
• Matching supply voltage range (10 V to 36 V)
• Matching operating temperature range (0°C to 70°C)

Mechanical Equivalence Requirements:

• Identical package type (16-SOIC)
• Identical package dimensions (0.154", 3.90mm Width)
• Surface mount configuration

The LM13700MX/NOPB meets all substitution criteria as a direct equivalent. Both parts share the same base product number (LM13700) and are manufactured by Texas Instruments with identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The LM13700MX/NOPB is the direct substitute for the LM13700MX. Both parts are manufactured by Texas Instruments and provide identical electrical performance and mechanical compatibility.

Product Status Consideration: The LM13700MX carries a "Not For New Designs" status, while the LM13700MX/NOPB is classified as "Active." For ongoing production and new applications, the LM13700MX/NOPB is the appropriate selection, as it maintains active manufacturing support and availability.

Compliance Consideration: The LM13700MX/NOPB is ROHS3 compliant, whereas the LM13700MX is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the LM13700MX/NOPB is the required choice.

Packaging Consideration: The LM13700MX/NOPB is supplied in Cut Tape (CT) and Digi-Reel® packaging, providing flexibility for both small-quantity and high-volume procurement. The original LM13700MX packaging specification is not detailed in the provided data.

Inventory and Availability: The LM13700MX/NOPB has significantly higher inventory availability (85,200 pcs) compared to the LM13700MX (22,900 pcs), supporting supply chain continuity and reducing lead time risk.

Frequently Asked Questions (FAQ)

Q: Can the LM13700MX/NOPB be used as a direct replacement for the LM13700MX?

A: Yes. The LM13700MX/NOPB is a direct substitute.
